Definitions
- the present invention relates to a radiating element, such as those present in particular in multi-band telecommunication antennas. These are in particular multi-band antennas, so-called panel antennas, intended more particularly for cell phone applications.
- GSM Global System for Mobile Communications
- UMTS Universal Mobile Telephone Service
- Operators of telecommunication networks must therefore have a network of antennas transmitting according to the various frequency bands used. For this, some operators set up complementary networks of antennas, each of these networks operating according to a telecommunication system. Thus, operators use a GSM antenna network and a DCS antenna network while they install a UMTS antenna network. However, as part of the deployment of their network, operators have difficulty getting permission to install new antennas. Current sites are already very crowded in terms of their visual impact. In addition, the proliferation of antenna networks entails increasing costs for operators - purchases of antennas, site rentals, facilities - as well as a deterioration of the environment.
- two-band or tri-band antennas are known in which the radiating elements assigned to each frequency are aligned either in parallel along a longitudinal periodic structure, or for example staggered, so as to ensure a radioelectric environment similar to all items radiating corresponding to the same frequency.
- These configurations lead to a significant increase in the width of the antenna, which degrades the radiation performance, at least for the highest frequency.
- a strabismus effect of the azimuthal pattern is caused by the asymmetry in the azimuth plane of the alignment of the radiating elements at high frequency.
- a dual polarization radiating element is formed of two independent dipoles each comprising two collinear conducting arms of a given polarization, positive or negative, for transmitting / receiving radiofrequency signals.
- the length of each arm is substantially equal to one quarter of the wavelength of the working signal.
- the radiating elements are mounted longitudinally aligned above a reflector, which makes it possible, by reflection of the rear radiation of the dipoles, to refine the directivity of the radiation pattern of the assembly thus formed.
- Each dipole of a radiating element is connected by a power line to an external source of energy. These radiating elements are dedicated to remission / reception of a single frequency.
- Radiating elements comprising four substantially triangular conducting arms which are orthogonally arranged with respect to one another in a horizontal plane, called cross-linked dipolar assemblies (or "cross-bow ties").
- radiating elements known as "butterfly" (or
- Butterfly formed of four conducting arms bent axially V and arranged orthogonally with respect to each other.
- Printed elements are also known, also called “patch” elements, comprising four conducting arms drawn by a conductive layer deposited on a dielectric substrate.
- the present invention therefore aims to provide a radiating element for a multi-band antenna that reduces its bulk.
- the object of the present invention is a multi-band antenna radiating element comprising a first pair of crossed double polarization dipoles each comprising two collinear conducting arms, the four conducting arms defining a first radiating plane corresponding to a low frequency band.
- the element radiating circuit further comprises at least a second pair of cross-polarized dipoles each comprising two collinear conducting arms, the four conducting arms defining a second radiating plane corresponding to a band of higher frequency.
- the first radiating plane and the second radiating plane are parallel, the second radiating plane being placed above the first radiating plane from which it is electrically isolated, and the surface of the first radiating plane covering the conducting arms of the first pair of dipoles is greater than on the surface of the second radiating plane covering the conducting arms of the second pair of dipoles.
- the lower radiating plane of lower frequency, is designed so as to provide sufficient surface area for the higher radiating plane, of higher frequency, so that it can be likened to a ground plane vis-à-vis the upper radiating plane. This is obtained with a surface covered by the dipoles of the lower radiating plane as large as possible.
- the first radiating plane is defined by a pair of printed dipoles and the second radiating plane is defined by a pair of dipoles chosen from cross dipoles, dipole dipoles and printed dipoles.
- the first radiating plane is defined by a pair of cross dipoles and the second radiating plane is defined by a pair of dipoles chosen from dipoles in cross of the dipole dipoles and printed dipoles.
- the cross dipoles comprise triangular arms.
- the cross dipoles comprise square-shaped arms.
- the cross dipoles comprise arms consisting of a volume fractal pattern.
- the cross dipoles comprise arms consisting of separate strands.
- the strands are separated by a distance less than or equal to ⁇ HF / 10 where ⁇ HF is the wavelength of the RF high frequency signal.
- the radiating element comprises three radiating planes superimposed in parallel: a first lower radiating plane, a second plane intermediate radiating plate placed above the first radiating plane from which it is electrically isolated, and a third upper radiating plane placed above the second radiating plane from which it is electrically isolated.
- the invention also relates to a multi-band telecommunications antenna comprising radiating elements as described above.
- the present invention has the advantage of reducing the width of the antenna, so its surface, which reduces its manufacturing cost and gives it a lower wind.
- the characteristics of the antenna comprising elements according to the invention are better than in the configurations of the prior art for two reasons.
- the radiating elements of a frequency band will be less disturbed by the radiating elements of the other frequency bands, because these become "invisible" to them because of the position of the dipoles one above the other.
- all the dipoles have a symmetrical environment.
