Definitions

  • the present invention relates to an antenna for mobile communications, particularly to a multi band antenna.
  • the antenna comprises at least one Low Band (LB) array and a plurality of High Band (HB) arrays, specifically one LB array and an even number of HB arrays.
  • the antenna may have a 1L2H, 1L4H, 1L6H etc. configuration (the letter“L” stands for Low Band, and the letter“H” stands for High Band).
  • the LB radiating elements of the at least one LB array are distributed over at least two HB arrays in all embodiments of the antenna.
  • LTE Long-Term Evolution
  • the new architectures should support 4x4 and 8x8 Multi-input Multi-output (MIMO) (which is necessary in higher frequency bands, but is also wished for in lower frequency bands, so as to be ready for future deployments). This means that the number of ports/antenna arrays needs to be duplicated at least in the higher frequency bands.
  • MIMO Multi-input Multi-output
  • any new antenna should be equivalent to legacy products, in order to maintain (or even improve) the coverage area and throughput.
  • the development of multiband antennas that can support LB plus a large number of HBs, i.e. 4 or 6 HB arrays, is being strongly demanded by the market. More specifically, in order to support 8T8R in the HB or 2 x 4T4R without duplexers, it is necessary to move from a“classical” configuration like 1 x 690-960 MHz + 2 or 3 x 1.7-2.7 GHz (1L2H or 1L3H) to more advanced architectures like 1L4H.
  • HB radiating elements Due to width limitations and the“high-density” of HB radiating elements in HB arrays, a key point of design for any new antenna is in particular the shape and arrangement of LB radiating elements for forming a LB array coexisting with a large number of HB arrays.
  • An example arrangement of LB radiating elements is the so-called side-by-side configuration, in which the LB radiating elements are of the cross-dipole type and arranged in the center of the antenna.
  • Such an arrangement is schematically illustrated in FIG. 14 for a 1LH4 configuration (wherein the number of LB arrays is denoted with“L” and of High Band arrays with“H”).
  • the HB arrays are arranged on both sides of the LB array and at the sides of the antenna, respectively.
  • the two outer HB columns would be omitted.
  • the shape of the LB radiating elements has a strong impact on the HB performance, and it is difficult to find suitable shapes that can overcome this problem and at the same time maintain the LB performance.
  • the distance between the HB arrays has to be relatively large, in order to avoid shadowing by the LB radiating elements.
  • FIG. 13 illustrates another example arrangement of LB radiating elements. All the LB radiating elements are here aligned and placed in a column that extends along the vertical antenna axis, and inserted in only one of the HB arrays. Thereby, the LB radiating elements are co-located/embedded with the HB radiating elements of that HB array. The other HB arrays are free from LB radiating elements.
  • the LB array cannot be placed in the center of the antenna, i.e. the radiation patterns are not symmetric.
  • an objective is to provide an antenna with a better arrangement of LB radiating elements for forming an LB array in an antenna that includes multiple HB arrays.
  • an arrangement of the LB radiating elements is desired, which is as transparent as possible for the HB arrays, and that can at the same time maintain the LB performance (Gain, HBW) of the legacy products (1L2H, 1L3H, etc.). This should still be achievable when increasing the number of HB arrays.
  • the LB array should be optimized with respect to both shape and arrangement of the LB radiating elements.
  • the LB radiating elements are distributed over at least two columns of HB radiating elements.
  • at least one LB radiating element is arranged in one of the at least two columns, while at least one other LB radiating element is arranged in the other one of the at least two columns. That means that at least two LB radiating elements are displaced relative to another in a direction transverse to the at least two columns of HB radiating elements.
  • a first aspect of the invention provides an antenna, comprising: a plurality of HB radiating elements configured to radiate in a first frequency band, and a plurality of LB radiating elements configured to radiate in a second frequency band which is lower than the first frequency band, wherein the HB radiating elements are arranged in multiple parallel columns and the LB radiating elements are distributed over two or more columns from the multiple parallel columns, wherein each LB radiating element is co-located with one of the HB radiating elements.
  • the expressions“high band” (HB) and“low band” (LB) refer to two different frequency ranges, namely a first frequency band (the high band) and a second frequency band (the low band), wherein it is understood that the HB is higher in frequency than the LB.
  • a lower range of the HB may overlap with an upper range of the LB.
  • the expressions HB and LB may also be used as attributes of nouns to indicate that the matter described by the respective noun is associated with a HB or with a LB, respectively.
  • a HB element is an element associated with a HB
  • a LB element is an element associated with a LB.
  • Each column of HB radiating elements may form a separate HB array, and the plurality of LB radiating elements may form a LB array.
  • the LB radiating elements are distributed over the two or more columns from the multiple parallel columns in the sense that each of the two or more columns comprises one or more of the LB radiating elements.
  • the arrangement of the LB radiating elements in the antenna of the first aspect leads to a (more) symmetric LB radiation pattern, and also to a (more) even performance of the different HB arrays or columns.
  • Square-dipoles can be used for the LB radiating elements, thus the LB gain can be improved. Shadowing of the HB radiating elements by the LB radiating elements can further be reduced.
  • the arrangement of the LB radiating elements is thus better than in the arrangements shown in FIG. 13 or FIG. 14.
  • the antenna comprises a LB feeding network connected to the plurality of LB radiating elements, for operating the plurality of LB radiating elements as a LB antenna array.
  • the antenna comprises for each of the multiple columns a HB feeding network connected to the HB radiating elements of the respective column, for operating the HB radiating elements of the respective column as a HB antenna array.
  • each HB radiating element column forms one HB array
  • the LB radiating elements form one LB array.
  • the antenna may e.g., be in a 1L2H, 1L4H or 1L6H configuration.
  • the two or more columns over which the LB radiating elements are distributed each comprise the same number of LB radiating elements.
  • the plurality of LB radiating elements is arranged along the columns in a zigzag pattern.
  • the LB radiating elements are arranged along the columns in accordance with cyclic permutations of the columns.
  • the multiple parallel columns are adjacent to another.
  • each of the LB radiating elements is located at least partly above or below the HB radiating element with which the LB radiating element is co-located.
  • the plurality of HB radiating elements is arranged in four parallel columns, which include two inner columns, and the plurality of LB radiating elements is arranged in the two inner columns.
  • the plurality of HB radiating elements is arranged in four parallel columns, which include two outer columns, and the plurality of LB radiating elements is arranged in the two outer columns.
  • the plurality of HB radiating elements is arranged in four parallel columns, which include an outer column and an inner column, and the plurality of LB radiating elements is arranged along the columns altematingly in the outer column and in the inner column.
  • the HB radiating elements and/or the LB radiating elements are arranged along the columns with non-uniform spacing.
  • each of the HB radiating elements and/or each of the LB radiating elements is dual-polarized.
  • the antenna further comprises one or more third radiating elements configured to radiate in a frequency band which is not the first frequency band and not the second frequency band.
  • a second aspect of the invention provides a base station comprising an antenna according to the first aspect or any of its implementation forms, and a radio transmitter connected to the antenna.
  • a base station may also be referred to in the art as a network access node, a radio client device, an access client device, an access point, e.g., a Radio Base Station (RBS), which in some networks may be referred to as transmitter,“gNB”,“gNodeB”,“eNB”,“eNodeB”,“NodeB” or “B node”, depending on the technology and terminology used.
  • RBS Radio Base Station
  • the radio client devices may be of different classes such as macro eNodeB, home eNodeB or pico base station, based on transmission power and thereby also cell size.
  • the radio client device can, for example, be a Station (STA), which is any device that contains an IEEE 802.11 -conformant Media Access Control (MAC) and Physical Layer (PHY) interface to the Wireless Medium (WM).

  • the antenna 100 is a multi-band antenna, as it combines a plurality of HB radiating elements 101 and a plurality of LB radiating elements 102.
  • the HB radiating elements 101 are configured to radiate in a first frequency band
  • the plurality of LB radiating elements 102 are configured to radiate in a second frequency band.
  • the second frequency band is thereby lower than the first frequency band.
  • the HB radiating elements 101 are arranged in two parallel columns, i.e. the antenna 100 is in a 1L2H configuration.
  • the LB radiating elements 102 are distributed over these two HB columns. Thereby, each LB radiating element 102 is co-located with one of the HB radiating elements 101.
  • the LB radiating elements 102 may be arranged in a zigzag configuration along the columns of the HB radiating elements 101.
  • the LB radiating elements 102 are altematingly displaced, along the HB columns (i.e. along a vertical axis of the antenna 100), in a direction perpendicular to the columns of the HB radiating elements 101.
  • each column of HB radiating elements 101 is referred to as a HB array
  • the plurality of LB radiating elements 102 is referred to as a LB array.
  • the radiation pattern of the LB array is made more symmetric by distributing the LB radiating elements 102, particularly totally symmetric if the LB radiating elements 102 are altematingly placed in one column and then the other column of the two columns of HB radiating elements 101. Further, the combined radiation pattern of the LB and HB arrays is made more or even totally symmetric.
  • the performance of the HB arrays (two HB arrays for the 1L2H configuration case) can be equalized.
  • the performance at array level of the two HB arrays may be much more balanced than if all the LB radiating elements 102 were arranged in only one HB array (as e.g., shown in FIG. 13). This leads to a better MIMO performance.
  • the arrangement of the LB radiating elements 102 in the antenna 100 described with respect to FIG. 1 is particularly advantageous, when a LB array is combined with an even number of HB arrays, i.e. 1L2H (as in FIG. 1), 1L4H (e.g., FIG. 2), 1L6H (e.g., FIG. 3), which are actually also the most valuable architectures from a market perspective, since the MIMO order always duplicates, i.e. goes from 2x2 to 4x4 to 8x8 and so on.
  • the arrangement of the LB radiating elements 102 can, however, be used also with other numbers of HB arrays.
  • the LB radiating elements 102 may be distributed over more than two HB arrays.
  • the performance of HB arrays located at the sides of the antenna 100 and of HB arrays placed in the center of the antenna 100 may be different, but still the overall performance between all the HB arrays will be more balanced than when placing all the LB radiating 101 elements aligned in one HB array.
  • FIG. 2 shows an antenna 100 according to an embodiment of the invention, which builds on the antenna 100 shown in FIG. 1.
  • FIG. 2 shows an antenna 100 in a 1L4H configuration, exemplarily when with LB radiating elements 102 distributed in a zigzag pattern over two of the four columns of the HB radiating elements 101.
  • the antenna 100 of FIG. 2 may this includes two different types of HB arrays, i.e. the two HB arrays located at the sides of the antenna 100 and the two HB arrays located in the center of the antenna 100. Notably, in the situation of the antenna shown in FIG. 13, the environment and therefore the performance of all four HB arrays is different. Thus, the antenna of FIG. 2 shows better performance.
  • a 1L4H antenna 100 which is based on the antenna 100 shown in FIG. 2, there may be six LB radiating elements 102 (not four as schematically illustrated in FIG. 2) placed alternatively in one of the two center columns of the HB radiating elements 101, i.e. co-located with HB radiating elements 101 from the second and third HB columns (counted from either side of the antenna).
  • the first and fourth column i.e. the columns located at the sides of the antenna 100, have similar performance, and also the second and third columns in the center of the antenna 100 have a similar performance. This is an advantage not only for the system performance (e.g., better MIMO performance), but also from a development and production point of view (only two different types of tuning and set of parts).
  • FIG. 3 shows an antenna 100 according to an embodiment of the invention, which builds on the antenna 100 shown in FIG. 1.
  • FIG. 3 shows an antenna 100 in a 1L6H configuration, exemplarily when distributing the LB radiating elements 102 in a zigzag pattern over two of the six columns of HB radiating elements 101. That is, like in the antenna 100 of FIG. 1 and FIG. 2, the plurality of LB radiating elements 102 is arranged along the columns in a zigzag pattern.
  • the antennas 100 shown in FIG. 1 (1L2H configuration), FIG. 2 (1L4H configuration) and FIG. 3 (1L6H configuration) have distinct advantages over the antenna types shown in FIG. 13 and 14 (exemplarily for the 1L4H configuration).
  • FIG. 12 depicts an example of an antenna in a 1L4H configuration not covered by the invention, in which all the LB radiating elements are arranged in one line.
  • the disadvantages of this type of antenna have been already mentioned above and are: • The LB radiation pattern is not symmetric.
  • FIG. 13 depicts another example of an antenna in a 1L4H configuration not covered by the invention, in which cross-dipole LB radiating elements arranged in the center of the antenna are used.
  • the radiation pattern of the LB array is more symmetric than in the antenna of FIG. 12, but the configuration has the following disadvantages:
  • the LB gain when using the cross-dipoles is typically 0.5 dB lower that when using square dipoles.
  • the LB radiating elements introduce strong shadowing in the array of the HB radiating elements, which makes it difficult to control the HB radiation pattern.
  • the distance between the two HB columns would have to be made relatively large, i.e. forcing to increase the width of the antenna and/or have non-uniform horizontal spacing between the HB columns and limiting the beamforming capabilities (due to large horizontal spacing, grating lobes appears, limiting the maximum scanning angle).
  • the embodiments of the invention are not limited to specific frequency bands, and therefore are not limited to any ratio of placing HB radiating elements 101 to LB radiating elements 102 along the columns (i.e. along vertical axis of the antenna 100).
  • the HB to LB ratio is determined by the positions along the vertical axis of the antenna 100, at which LB radiating elements 102 are arranged in parallel HB arrays with aligned HB radiating element positions. For instance, if a LB radiating element 102 is placed at every second position in either one of parallel HB arrays (one free position between LB radiating elements 102), the HB to LB ratio is 2: 1.
  • the HB to LB ratio is 3 : 1. If a LB radiating element 102 is placed at every fourth position in either one of parallel HB arrays (three free positions between LB radiating elements 102), the HB to LB ratio is 4: 1, and so on.
  • the embodiment of the antenna 100 shown in FIG. 1 is optimal for a combination of frequencies of 900/2000 MHz. Therefore, the HB to LB ratio is 2: 1 along the vertical axis of the antenna 100, i.e.
  • a LB radiating element 102 is co-located with a HB radiating element 101 at every second position along the two parallel HB radiating element columns (while at the same time being distributed over the two HB columns).
  • the HB to LB ratio may be different, and there may even be cases, in which the optimal HB to LB ratio is non-uniform along the vertical axis of the antenna 100, i.e. a spacing of LB radiating elements 102 along the vertical axis may be non-uniform.
  • the embodiment of the antenna 100 shown in FIG. 3 has LB radiating elements 102 co-located with HB radiating elements 101 in the central HB columns, i.e. the second and third column, at every second position along the vertical axis of the antenna 100.
  • This configuration is optimal for the frequency band combination 900/2000 MHz, but may not be optimal for different frequency bands.
  • the optimal solution is to arrange the LB radiating elements 102 co-located with the HB radiating elements 101 with a different HB to LB ratio, or in the side columns, or even alternatively co-located with HB radiating elements 101 in the side columns and central columns.

Abstract

La présente invention concerne une antenne pour communications mobiles comprenant une pluralité d'éléments rayonnants à bande basse (LB) et une pluralité d'éléments rayonnants à bande haute (HB). Les éléments rayonnants LB peuvent fonctionner comme un réseau LB tandis que les éléments rayonnants HB peuvent fonctionner comme un nombre pair de réseaux HB. Par exemple, l'antenne peut avoir une configuration 1L2H, 1L4H, 1L6H, etc. Les éléments rayonnants HB sont agencés dans de multiples colonnes parallèles et les éléments rayonnants LB sont répartis sur deux colonnes ou plus à partir des multiples colonnes parallèles, chaque élément rayonnant LB étant co-localisé avec l'un des éléments rayonnants HB. L'antenne présente une bonne performance de rayonnement.
