Description

The invention relates to a compact and efficient millimeter transmitter and / or receiver 5 (EHF) for a Point-to-Multipoint or "PmP" communication system making it possible to achieve a coverage. ground or "footprint" optimized according to the distribution of system customers. It finds its applications in the field of very high-speed point-to-multipoint communications for the backhaul access point of mobile radio stations or WiMAX standard stations or Wi-Fi hotspot terminals or even businesses or buildings. . PmP systems consist of a central station distributing information flows to terminals connected to mobile radio base stations, hot-spot terminals, buildings, businesses, etc. The central station distributes these bidirectional flows to its customers by sector from three to six, for example. In a given sector, the flow of information is sent to all the subscribers there and this flow covers the entire sector. As a result, the spectrum is misused, the energy sent to customers is not optimized, and therefore the capacity and range of the system is limited. Indeed, the area covered by the radiation of the antenna being wide, the gain of the antenna is lower, which is unfavorable for the link budget. This limits in scope the use of high order modulations (16QAM and more) at the edge of the cell and results in a fall in the capacity of the telecommunications system. In addition, since the radiating aperture of the antenna is wide, it is necessary to change the frequency from one sector to another to avoid interference with the intersections of the sectors. In order to increase their capacity these systems generally use millimeter carrier waves (EHF) because the available frequency bandwidths are wider. But propagation losses are higher and are very sensitive to atmospheric conditions especially in the presence of rain, which will limit the coverage for a given system capacity or symmetrically the capacity of the system for a fixed coverage area. However, even if the broad spectrum in EHF makes it possible to obtain much higher capacities than those of the other bands of the spectrum, the demand for debiting continues to grow as the need for coverage. The growth of capacity therefore depends on the good reuse of this spectrum, especially from one sector to another, and the range depends on the gain of the radiating system. We could increase the number of sectors with antennas more directive, but the disadvantage would be to significantly increase the prices and in particular the rent of the sites on the pylons or buildings which constitutes the principal post of the cost of operation (OPEX). On the other hand, by increasing the number of sectors, the place would be lacking to install the many antennas on buildings and small pylons. In summary, the reach and capacity of the headend must be increased without increasing the number and size of equipment. In order to better understand the problem in order to improve the millimeter PmP systems, we first define what the radio footprint should be in relation to the current footprint.

The current footprint is shown in FIGS. 1A and 1B for a four sector headend, 11, 12, 13, 14. A headend 15 illuminates the ground 16 with a lobe. Two alternating frequency sub-ranges F1 and F2 are used for these four sectors, the four corresponding lobes are made by four transmitters / receivers each associated with a sectoral antenna of 90 °. The width of the spectrum of these sub-ranges is proportional to the capacity to deliver one or more information flows in each sector. All the terminals in each sector receive the energy of the spectrum F1 or that of the spectrum F2. It is therefore limited in capacity by the use of the spectrum, and in range by the low gain of sectorial antennas.

One of the objectives of the invention is to verify one or more of the following five properties in a given sector: a geometric cover adapted to the customers' request, a reduction of the diffuse lobes of radiation to prevent the cover from overflowing on a neighboring sector 5, a capacity adapted to the needs of customers in each of the covers made in the sector, a significant increase in scope and a realization to compactness equal to that of the prior art. The product according to the invention is an EHF transmitter and / or receiver which distributes, in a given sector, at least two groups or multiplexes of 10 very high capacity telecommunications channels, these two groups of channels are distributed in at least two zones. corresponding to the distribution of two groups of target customers, both groups of customers being allocated a capacity corresponding to their needs; the link budget, the reuse of the spectrum in the neighboring sector and the use of the cross polarization are respectively improved and concomitantly by a factor of at least two compared to the state of the art while maintaining the same spatial volume or bulk. The term "product" in the description refers in particular to the transmitter and / or receiver with its antennas according to the invention.

The terms SHF and EHF denote frequency ranges according to the IUT, with SHF: especially high frequency corresponding to centimetric waves, EHF: extremely high frequency corresponding to millimeter waves. The invention relates to a compact and efficient multi-layer transmitter and / or receiver device (EHF) of a communication system that makes it possible to provide ground cover or "footprint" optimized according to the topography of the customers by the distribution of at least two very high-speed streams and allowing the reuse of frequencies in neighboring sectors, the use of cross-polarization, the doubling of the range, characterized in that it comprises at least two multilayer blocks stacked and connected in EHF A first multilayer block called "active" adapted to provide transposition and amplification functions as well as the distribution of at least two intermediate frequency input / output streams f'1 and f'2 in SHF, to at least two inputs or outputs "T1" and "T2" in 5 EHF coupled to a second radiating multilayer block realizing at least two directions of radiation or lobes whose gold It is provided by said first active multilayer block, the second "radiating" block is superimposed on the first "active" block by the input-outputs and adapted to realize several directions or lobes F'1 and F'2 in EHF thus distributing in the free space at least two input / output streams independent of at least two groups of customers, the structure of the second block being defined in order to obtain the desired deposit imprint, a gain, a yield, a decoupling of the cross polarization, a level of user-defined secondary lobes. According to one embodiment, the first active multilayer block comprises: at least two inputs output on the intermediate frequencies carrying the different streams intended for one or more groups of users, the flows being introduced into a 90 ° hybrid coupler, of which the outputs are directed to at least two digital phase shifters, each receiving a control band C, in order to position the lobes of the radiating multilayer block and cover the desired surfaces where said users are located, the outputs of each of these phase-shifters then being filtered by at least one band filter in order to limit in transmission as in reception the intermodulation phenomena generated by the transpositions in the transmitters or receivers, each signal after filtering being introduced on a component adapted to transpose, amplify the signal, the inputs or outputs of these MMIC components being directed on "T1" transitions e These "EHF" guides connect the radiating elements of the "radiating" multilayer block, the MMIC components receiving a local oscillator in SHF. The second "radiating" multilayer block comprises, for example, at least the following elements: a first metal plate supporting the assembly and ensuring the connection of the "T1" and "T2" transitions of the active multilayer block by means of minus two connectors, - a dielectric layer transparent to the waves holding in place, - a conductive metal layer forming the supply lines of the radiating elements, - a dielectric layer substrate supply lines for performing a micro-circuit ribbon, 15 - a layer consisting of a dielectric glue, - a layer consisting of a metal sheet pierced with two rows of etched slots, - a layer constituting the dielectric substrate of the set of etched slots, 20 - a metal layer comprising patch networks, the slot-dielectric-patch assembly constituting the radiating element fed by the lines of the layer which are connected to the connectors. According to one embodiment, the footprint on the ground consists of at least two lobes whose position in the bearing and the width are adaptable in position (bearing) by the active multilayer and in width by the radiating and focusing multilayer. . The first active block is, for example, made in SHF, especially high frequency corresponding to centimetric waves. Other characteristics and advantages of the system and the method according to the invention will appear better on reading the detailed description which follows, given by way of illustration and in no way as limiting, of the figures which represent: FIG. 1A is an example of imprint according to the prior art, made by a transmitter or a receiver and a column antenna or row of 5 patches or by a horn performing a standard sector of 90 °, and Figure 1B schematizes the diagram in site for the cover in FIG. 2A is the imprint obtained by a radiation pattern having at least two lobes in the field and of adaptable width (aperture) distributing different information streams, and FIG. 2B shows the site diagram with a cosecanted antenna making the coverage more homogeneous distance, - Figure 3 represents the general diagram of the final product with two inputs or outputs frequency intermediate SHF, F'1 and F'2, its EHF antenna radiation lobes in the plane of the deposit and its constitution in two multilayer blocks one active and the other radiating, - Figure 4, the standard diagram for the realization of the active part 20 (emission or reception) and the formation of at least two adaptable lobes, - Figures 5A and 5B, the principles of the basic and improved radiating elements, - Figure 6 presents the multilayer arrangement of the radiating portion, and - Figure 7, several examples of possible diagrams of the focuser according to the selected parameters, - Figures 8A, 8B and 8C, an illustration of the patch columns and feed lines.

The invention is based in particular on the following idea: instead of an almost uniform coverage and a global distribution, in each given sector, distributed, differentiated and adaptable capacity will be distributed to predefined zones in a given sector. The radiation pattern of the antenna associated with a transmitter and / or receiver must have at least two lobes of radiation and weak secondary lobes. In addition, the antenna must have good radiation efficiency and good cross polarization decoupling. This coverage or footprint provided by the radiation of the antenna must be reduced in size and equivalent to existing equipment, prior, (square of 10cm side, for example) because the cost of renting on pylons and buildings is 10 the post Main Operating Costs (OPEX). The typical footprint to be produced is shown in FIGS. 2A and 2B. It consists of at least two lobes L1, L2, using sub-ranges of frequencies F'1 and F'2 within each sector 20, 21, 22, 23. These lobes L1, L2 are positioned to at least two groups of clients R1, R2 which will each receive a different and diversified capacity corresponding to their needs defined by the widths of the sub-bands F'1 and F'2. The radiation pattern should include limited diffuse lobes not to "drool" in neighboring areas (spectrum reuse) as well as minimal cross-polarization to double the capacity by carrying different information on the other polarization of the spectrum. millimeter wave. The structure of the transmitter and / or receiver 25 according to the invention makes it possible to obtain such a result. There are then two groups of at least one communication channel using the same frequency sub-band.

In order to take account of the cost-limiting congestion constraint, a solution of the same compactness as that of the prior art requires an original architecture and technological assembly that provides the above-stated properties while reducing costs. This implies, in particular, compared to the prior art, to design radiating elements other than with simple plates better known by the Anglo-Saxon name "patches" (to ensure compactness), for example on the figure 3034268 5A. Indeed, several rows or columns of patches, can not be brought closer than 0.7 * to (with the wavelength of the radiation) because of their supply lines which will create diffuse lobes. On the other hand, the patch columns provide a bias decoupling of at best 12dB (in the direction perpendicular to the S and G axes in FIG. 3) which makes it difficult to separate the communication channels on the two crossed polarizations from one another. beyond the QPSK modulation order. The information provided or received by the transmitter and / or receiver according to the invention consists of two information flows coming from at least two broadband modems (401, 402, FIG. 4), these flows are transported on two intermediate frequencies f'1 and f'2 and according to principles well known to a person skilled in the art. These intermediate frequencies transporting the streams will be transposed by the EHF product at frequencies F'1 and F'2 and radiated by the antenna on the lobes covering the predefined surfaces associated with one or more groups of users. The transmitter / receiver has the following radiation pattern properties: doubled gain, adaptable position and aperture, low side lobes, strong cross polarization decoupling.

An exemplary product produced in a first "active" multilayer block and a second "radiating" multilayer block that provides the desired radiation pattern and in particular the desired deposit pattern, the two blocks being stacked and interconnected, are described below. . The very compact transmitter and / or receiver according to the invention (FIG. 3) is designed in multilayer technology comprising different dielectric substrates and metal layers in order firstly to obtain the properties mentioned above and secondly to obtain a reduced realization cost. FIG. 3 illustrates an exemplary architecture of the transmitter and / or receiver according to the invention. The radiation is oriented along two axes: an axis in S (vertical) and a G (horizontal) axis. It is known that in order to make flat and compact antennas, antennas are produced by discrete radiating elements which are coupled and connected together. Thus along the axis S one will combine in column, ten to twenty radiating elements so as to create a diagram in site of a few degrees 12 ° to 6 °, for example, in order to ensure coverage on the desired distance as it 5 is shown in Figure 1B (footprint site), the holes of diagrams will be filled by the arrangement along the axis S of the radiating elements (cosecantée antenna principle) Figure 2B (footprint site). In order to make lobes in the G axis (FIGS. 2A and 3), at least two ranks or columns of radiating elements (FIGS. 8A, 8B, 8C) will be used.

The lobes and their positioning are respectively obtained by the coupler C and the digital phase shifters (Pi and 02 of the active circuit described in FIG. 4). This product, emitter and / or receiver, which is very compact in multilayers, comprises, according to FIGS. 4, at least two multilayer blocks stacked and connected in EHF: the first multilayer block 31, called "active", provides the functions of transposition and amplification of a signal as well as the distribution of at least two input streams / output 33, 34, 41, 42 (FIG. 4) at intermediate frequencies f'1 and f'2 in SHF, to at least two inputs or outputs T1 and T2 (471, 472, FIG. 4) in EHF coupled to a second radiating multilayer block 32 producing at least two radiation directions or lobes whose orientation of these directions or lobes is provided by this first active multilayer block, the second multilayer block called "radiating", 32 superimposed on the first block " active "by the entrances T1 and T2 microwave outputs and realizing directions or lobes F'1 and F'2 in EHF thus distributing in the free space the flows on the inputs / outputs of the modems 41, 42, independent of at least two groups of clients . This second radiating multilayer block provides the properties required by the PmP system, i.e., the desired deposit pattern, as well as gain G, yield n, decoupling D of the cross polarization as well. 10 that a level A of secondary lobes. All these properties make it possible to at least double the capacity and the range obtained by a radio head having only a transmitter or receiver sectorial antenna to the state of the art. The inputs / outputs 5 are hyper at the same point as the transitions that form the device for moving from a microstrip track to the connector of the antenna. A detailed example of an active part (active block 31 FIG. 3) is shown in FIG. 4. The multilayer circuit referenced 25 FR and known to those skilled in the art makes it possible, at low cost, to produce the active multilayer sub-assembly, the The use of the 25FR (or equivalent) is made possible by the fact that the operations are essentially performed at intermediate frequencies SHF: the signals of the broadband streams (typically several hundred MHz) are injected on the frequencies f'1 and f'2 ( typically in the C band around 4 or 6GHz) on the connectors 41 and 42 (standard connectors of the MCX or SMA type marketed by the company Rosenberg) and introduced into a hybrid coupler 90 °, 43, of the Micro Xinger type (model1 M803 marketed by Anaren). The outputs of the coupler 43 are directed towards two digital phase shifters 441, 442, (Pi and 20 (P2, band C known to those skilled in the radar art, for example, which will allow, by a "P" command of a few bits for example, to position the lobes of the radiating block on demand and thus cover the desired surfaces as a function of one or more user groups The outputs of these phase shifters <: P1 "and" 02 "are filtered by filters band "BPF", 461, 462, their role is to limit, in transmission as in reception, some intermodulation products generated by the transpositions in the transmitters or receivers, the signals after filtering are introduced on the components M1 and M2 in MMIC technology (Microwave Monolithic Integrated Circuits on AsGa) performing the functions of transposition and amplification (mixing and amplification of power in transmission, low noise amplification and mixing in reception). oduits exist at AsGa's EHF founders 3034268 11 for these functions: United Monolithic Semiconductors or UMS, OMMIC, AVAGO. MMICs must be matched in gain. These MMICs are plotted on microstrip lines and the inputs or outputs are made by micro-ribbon transitions to the guides T1 and T2 for connection to the radiating elements. The MMICs receive a frequency of the local oscillator 480 by lines of the same length. It should be noted that the MMICs generally have a local oscillator frequency multiplier so that the oscillator 480 operates in SHF, thus allowing the use of multilayers of the 25FR type. Finally, the 10 active elements MMIC and the phase shifters are powered by the power supply unit 490 creating the necessary DC voltages. The multilayer circuit 25FR on which the elements are implanted and connected is, for example, electrically and thermally bonded to a thick metal layer or "platinum" which provides both the mass, the heat conduction and the receptacle of the radiating system. The radiating system using multilayer technology is presented in FIG. 6. In order to understand the operation thereof, the principles which make it possible to obtain a compact antenna system having the desired properties are first described. The width of the desired main lobes and parasitic secondary lobes are defined by the radiating elements and by the focusing device, an exemplary architecture of which is shown in FIGS. 5A and 5B. It is indeed necessary to design radiating elements whose main properties will be the yield, the limited cross polarization, and the compactness of association (it would be impossible to associate several rows of patches relatively closely because of the congestion of their power lines, the inter-column distance would then be greater than 0.7A and create network lobes thus parasitic). To obtain all the functionalities of the product and in particular the announced radiating properties, the core of the radiating element is a "feed-slot-patch" combination according to the diagram of FIG. 5A, it is supplemented 3034268 12 at the base by a reflector and "interface-air" by a focusser according to Figure 5B. Figure 5A illustrates the principles of the core of the "feed-slot-patch" radiating element. It is composed, for example, of a first metallization circuit 51 on which is disposed a first dielectric substrate 52, on which there is a ground plane 53 provided with a slot 53f whose dimensions are chosen to allow the radiation , then a second dielectric substrate 54 covered with a second metallization circuit 55.

FIG. 5B schematizes a variant in which the core of the radiating element also comprises a focusser and a reflector. The references used in FIG. 5A have been used to designate the same elements. In this example, a metal reflector 56 is disposed below the first metallization circuit 51 of FIG. 5A and a third dielectric substrate is disposed above the metallization circuit of FIG. 5A. According to these principles, there is then described according to FIG. 6, an example of the layer organization of the sub-assembly or "radiating" block, the values indicated in this figure are given for illustrative purposes, they will be chosen according to the materials and applications. The block comprises, in this example, ten layers of dielectric, metal or glue in order to obtain the described properties. At the base, a first metal plate 600 and a second metal plate 601 (layer 1) support the assembly and connect the T1 and T2 transitions of the active multilayer (FIG. 4) by means of at least two connectors of "mini" type. SMP "not shown in the figure, the role of this plate is also to ensure reflection phase addition of the back radiation of the waves from the feed lines 603 placed on the layer 604 and slots etched on the layer 606 A layer 602 which is a dielectric transparent to the waves and quite rigid (ex: Rohacell 31 HF) ensures the maintenance in place. The thickness of the foam layer 30 should be λ / 4 equal to 1.7 mm if the operating frequency is 13 GHz, for example (λ 0 being the wavelength in vacuum) in order to obtain a phase addition of the waves. Above the foam layer 602 is a conductive metal layer 603 (etched copper) of thickness 0.017 mm, for example. It realizes the supply lines of the radiating elements. For this we have at least two parallel rows of radiating elements in the vertical plane and separated by a maximum of 0.7A0, the number of supply lines in the vertical plane depends on the radiation pattern and the desired gain in site (typically from 12 to 20) e.g. 18 lines (801 Fig. 8A) will provide about 17dBi. Above is a layer 604 which is the dielectric substrate of the supply lines for producing a micro-ribbon circuit (Example RT Duroid 5880), for example c = 2-3. Above layer 604, in order to connect the microstrip power supply circuit to the slot radiating circuits, a layer 605 is made of a dielectric glue (eg Alron Cuclad 6700), the glue having a value c close to those of the layers 604 and 607. On the glue layer 605 is disposed a layer 606 constituted, for example, of a metal sheet pierced with two rows of etched slots (810 figure 8C), of thickness varying between 0, 04 and 0.05 mm. These slots will allow the coupling between the supply lines 603 and the patch antennas 608. Above the layer 606 constituting the ground plane and the slot for the radiation, a layer 607 constitutes the dielectric substrate of the set of engraved slots, the same dielectric is used for the supply lines (example RT 5880), for example a permittivity c = 2-3. On the same dielectric 607 and aligned on the slots a metal layer 608 comprises the patches (etched copper), the thickness of this layer is for example equal to 0.017 mm. The slit-dielectric-patch assembly constitutes the radiating element fed by the lines of the layer 603. In order to fix the values of all the vertical and horizontal dimensions of the multilayer and the choice of the materials, a simulation software will be executed in order to to determine according to measurements the parameters, characteristics of the various elements constituting the block. This will adapt the antenna to the desired frequency range. For this purpose it is advisable to use a software type CST Microwave and for measurements a network analyzer (VNA) of the market.

It remains to better focus these radiating elements (in particular to specify the bearing diagram and to reduce the secondary lobes), for this purpose, a dielectric with a thickness dl close to λg / 4 is placed above the last layer 608, distance d2 close to λ0 / 2 (λg is the wavelength in the dielectric and λ0 the wavelength in vacuum or in a transparent dielectric). For this, in the example is used a first layer 609 made by a dielectric transparent to the waves and rigid (example: Rohacell 31 HF), for example À0 / 2 +/- 30% and a thickness d2, and a second layer 610 made by a dielectric RT 6006 or 6010 with a thickness d1, for example À0 / 2 +/- 30% depending on the desired effect and a substrate c = 6-10. The desired modification of the final diagram depends on the thicknesses and the epsilon (permittivity c) of the dielectric, different options for modifying the diagram according to the adjustment of the three parameters c (dielectric), d1, d2 of the focusser are possible depending on the effect desired: wide lobes may be preferred to cover clients with weak side lobes for frequency reuse in the area or narrower lobes (if the client groups are more concentrated with more gain. the needs can be obtained as shown in FIG. 7 by playing on the parameters d1 and d2 according to the permittivity As in the previous paragraph on the core of the radiating elements, the simulations are carried out by CST Microwave and the measurements with a VNA for design the desired effect and also generically for adaptation to the frequency range.The dimensions of the different necks The nature of the materials used to make the device and the adaptation of the gain and frequency set are determined by implementing a simulation iteration methodology to obtain or converge to the specifications. established by the user specifications. Figure 8A illustrates two parallel columns 802, 803 of radiating elements 801.

FIG. 8B is an illustration of two feed columns 806, 807 connected to two connectors using the cavities 808, 809. FIG. 8C illustrates a ground plane having two rows of slots 810, 811. The device and produced according to FIG. the invention offers the following advantages in particular: the solution makes it possible to distribute differentiated flows in a sector to at least two groups of users that are geographically neighbors but angularly separated; the solution makes it possible to focus the energy on the only areas where there are customers, - the solution makes it possible to reuse the spectrum easily in a neighboring sector, - the solution makes it possible to distribute fluxes on the crossed polarization beyond the QPSK modulation order, 20 - by the two advantages previous, the capacity of the PmP system can be multiplied by 2, - the link budget is multiplied by at least 4 (case of two lobes) so the range by 2 in the absence of rain, - The multilayer construction facilitates manufacturing, reduces its cost and provides a compact product (10cm side), therefore the rental cost on sites (a significant part of the cost of OPEX PmP systems) is limited.
