Definitions

  • the present invention relates to a radio frequency (RF) module, intended to form the passive part of a direct radiating antenna (DRA, Direct Radiating Array).
  • RF radio frequency
  • Antennas are elements that are used to emit electromagnetic signals into free space, or to receive such signals.
  • Simple antennas such as dipoles, have limited performance in terms of gain and directivity.
  • Parabolic antennas allow higher directivity, but are bulky and heavy, which makes their use unsuitable in applications such as satellites for example, where weight and volume must be reduced.
  • DRA antenna arrays are also known which bring together several radiating elements (antenna elements) out of phase in order to improve gain and directivity.
  • the signals received on the different radiant elements, or emitted by these elements, are amplified and phase shifted between them so as to control the shape of the reception and transmission lobes of the network.
  • the different radiating elements are all connected via a waveguide network to a port making it possible to connect the antenna to an electronic circuit comprising for example an RF electronic circuit and an amplifier .
  • dual polarization antennas capable of simultaneously transmitting or receiving signals with two polarizations.
  • the signals transmitted or received by each antenna element are combined, respectively separated, according to their polarization by means of a polarizer.
  • the polarizer can also be integrated into the antenna element.
  • a dual polarization antenna has two ports for connecting each of the two polarizations separately to the electronic circuit respectively.
  • Such antennas intended to transmit high frequencies, particularly for microwave frequencies, are difficult to design. It is in particular often desired to bring the different elementary antennas of the network as close as possible in order to reduce the amplitude of the secondary transmission or reception lobes, in directions other than the direction of transmission or reception which must be favored. . This reduction in the pitch between the different elementary antennas of the network is however incompatible with the bulk of the waveguide network necessary in order to combine the signals received by the different elementary antennas, respectively to divide the signals to be transmitted.
  • Another goal when designing such an antenna is also to reduce its weight, particularly in applications for space or aeronautics.
  • One goal is to provide an antenna adapted to the Ka frequency band, in particular for satellite communications with LHCP and RHCP polarization.
  • antennas with a new modular design which makes it possible to vary the number of elementary antennas according to needs, without having to review the entire design of the antenna.
  • the design is said to be modular when different types of antennas can easily be designed by adding or removing standardized antenna elements during the design of the antenna, without having to revise the entire design of the antenna or array. waveguides. It is particularly desirable to be able to design an antenna in a modular manner by adding units with several antennas while guaranteeing spatial filtering.
  • the antenna must also of course have very high efficiency, gain and radiation pattern characteristics that are compatible with the application specifications.
  • the antenna must be able to be manufactured industrially and without falling within the scope of existing patent protection.
  • This structure makes it possible to produce a network of elementary antennas, subsequently simply called an antenna, in a modular manner by juxtaposing antenna units each formed from four superimposed elementary antennas.
  • Each antenna unit has two junctions 1-to-4 and thus makes it possible to receive and respectively transmit signals according to two distinct polarizations.
  • Each antenna unit thus comprises four antenna elements superimposed but offset in pairs.
  • the arrangement of the antenna elements of each unit in two planes offset from each other in a perpendicular direction at the plane of the blade at a distance less than the width of an antenna element makes it possible to carry out beamforming, or spatial filtering, of signals received or transmitted within a cell unit, such that in In particular directions, the signals interfere constructively while in other directions the interference is destructive.
  • This beamforming at the elementary level of each unit allows more freedom when combining antenna units since each antenna unit already has pairs of phase-shifted antennas. It also facilitates the connection of the different antennas by means of the waveguide network connecting the antennas together.
  • the number of antenna elements is preferably exactly four.
  • the divider/combiner array that connects the antenna units to the ports preferably comprises a first divider/combiner subarray comprising a stack of juxtaposed blades. It is thus easily possible to produce an antenna comprising a greater number of elementary antennas by adding additional blades and/or by increasing the number of cell units per blade.
  • the first subnetwork of dividers/combiners is arranged to connect the trunks of each 1-to-4 junction of this blade together.
  • Certain blades are associated with a first polarization and other blades are associated with the second polarization.
  • the first subnetwork of dividers/combiners in the blades associated with the first polarization is arranged to connect together the junction trunks 1-4 associated with this first polarization.
  • the first subnetwork of dividers/combiners in the blades associated with the second polarization is arranged to connect together the trunks of junctions 1-4 associated with this second polarization
  • the first subnetwork of dividers/combiners advantageously comprises an alternation of first blades associated with the first polarization and second blades associated with the second polarization.
  • each blade is dedicated to a single polarization.
  • the antenna advantageously comprises a second sub-network of dividers/combiners arranged to connect said first blades to each other and to the first port, and to connect said second blades to each other and to the second port.
  • Each blade preferably extends in a first direction substantially perpendicular to the direction of transmission of the signal, and between the two planes defined by the extreme lateral edges of the antenna elements associated with this blade.
  • a first blade and a second blade preferably extend between the two planes defined by the extreme lateral edges of the antenna elements associated with these two blades.
  • the width of the network dividers/combiners is less than or equal to the maximum width of the associated antenna elements; the total width of the antenna is therefore given by the width of the network of elementary antennas, and it is possible to add new antenna elements and connect them without the network of dividers/combiners determining the total width .
  • the second subnetwork of dividers/combiners is advantageously provided between said blades and said ports.
  • the second subnetwork of dividers/combiners preferably comprises waveguide portions extending in a second direction substantially perpendicular to the direction of signal transmission.
  • each blade is associated with four cell units.
  • Each antenna element can be connected to two neighboring blades.
  • the antenna comprises 32 blades, including 16 associated with a first polarization and 16 associated with the second polarization.
  • the first subnetwork of dividers/combiners of each blade has at least one bifurcation in the H plane.
  • Each antenna element preferably comprises a septum for combining in transmission or separating in reception the two polarizations of a radio frequency signal.
  • Each antenna element preferably has a cross section perpendicular to the direction of propagation of the square-shaped signal.
  • the antenna can be made monolithic.
  • the antenna can be produced by 3D printing a core and deposition of a surface layer at least on the internal face of this core.
  • the present invention generally relates to an antenna array, hereinafter simply called an antenna, and comprising several elementary antennas 3 (radiating elements) arranged in a matrix so that the openings of these elementary antennas are all in the same plane. .
  • the direction d of signal transmission, in the antenna and at the output of the antenna, is perpendicular to this plane.
  • FIG. 1 illustrates an antenna 1 comprising four juxtaposed cell units 8, each cell unit comprising four superimposed elementary antennas 3.
  • Antenna 1 of this example thus comprises 16 elementary antennas, numbered by line and column from 3 0;0 to 3 3;3 and forming a matrix with four lines and four columns, each column being formed in this example of a single cell unit.
  • the number of columns can be increased by juxtaposing additional cell units, and the number of rows can be increased by superimposing additional cell units within each column.
  • the pitch between two adjacent antenna elements as well as the pitch between two lines is advantageously less than the nominal wavelength of the signal to be transmitted; this reduces the unwanted secondary lobes in transmission or reception sensitivity.
  • the successive lines of the antenna are out of phase; in the example illustrated, the even lines are phase shifted with respect to the odd lines by a step corresponding to the half-width of an elementary antenna.
  • This phase shift makes it possible to carry out beamforming or spatial filtering of the signals received or transmitted by the antenna elements of the cell unit 8, such that in particular directions, the signals interfere constructively while in other other directions the interference is destructive.
  • the antenna elements 3 each include an opening forming a radiant element oriented towards the ether, and two connection ports at the junction 5 described below. One of the two ports is intended for a first polarization and the second is intended for the second polarization.
  • the antenna includes a polarizer, preferably in the form of a septum 32 making it possible to separate the two polarizations LHCP and RHCP of a signal in reception respectively to combine the two polarizations in transmission.
  • the antenna elements 3 may comprise another type of polarizer, or be linked to a separate polarizer.
  • the antenna 1 further comprises a series of junctions 1-4 5.
  • Two junctions 5 are associated with each cell unit, in order on the one hand to divide respectively combine the first polarization LHCP signals of the four elementary antennas of the cell unit, and on the other hand divide respectively combine the second polarization signals RHCP of the four elementary antennas of the cell unit.
  • the number of 1-to-4 junctions 5 is therefore equal to 8.
  • the signals at the output of the junctions 5 are combined using a first power divider/combiner in the H plane, separately for each polarization.
  • a port 7 ( figure 8 ) allows each polarization to be connected to an active electronic circuit.
  • THE figures 2 to 4 illustrate an example of a first divider-combiner 4 with the junctions 1-to-4 of the associated cell units, in the case of a dual polarization antenna comprising 16X16 antenna elements 3.
  • the first divider/combiner is made up of several 2 blades juxtaposed, each blade being dedicated to one of the two LHCP or RHCP polarizations. As each antenna element provides two polarizations, the number of blades is therefore equal to twice the number of antenna elements per line, that is to say 32 blades in this example.
  • Each blade 2 is intended to be connected to all of the antenna elements 3 of a column, that is to say to four cell units 8 superimposed in this example. It therefore comprises branches 500 0 to 500 15 , each of these branches being directly connected to one of the two output ports of one of the antennas.
  • Two levels of 1-to-2 junctions in the H plane form a 1-to-4 junction (reference 5) allowing the signals to be combined/divided within each cell unit 8; the signal common to the trunk 501 of the junctions of the blade 2 is combined using two additional levels of junctions 1-to-2 in the plane H, the signal resulting from the addition of the signals in all the branches 500 of a blade 2 thus finding itself at the trunk 23 of this blade.
  • FIG. 2 illustrates a single blade 2.
  • the Figure 3 shows two juxtaposed blades, one being dedicated to a first LHCP polarization of several superimposed cell units and the other to the second polarization RHCP of the same cell units.
  • FIG 4 illustrates the juxtaposition of 32 blades 2 constituting the first network of dividers/combiners of the antenna.
  • FIG. 5 illustrates a 1-to-4-5 junction present in each cell unit.
  • the junction therefore comprises four branches 500 intended to be connected to four ports of the antenna elements 3 of a cell unit 8.
  • the first level includes two junctions 1-to-2 51 for combining/dividing the signals in two by two. same polarization of two superimposed antenna elements. The two antennas of each pair being out of phase, the junction is made in the H plane.
  • a second 1-to-2 junction 50 then makes it possible to combine together the trunks of the two junctions 51, united in a common trunk 501.
  • THE figures 6 and 7 illustrate an example of a 1-to-2 junction in more detail.
  • This example relates to the first power divider/combiner 21 in the first network 4; however, the realization of the 1-to-2 junctions 50 and 51 in the cell units, and of the second power divider/combiner 22 in the first network 4 may be identical or similar, only the direction of the branches of the junction differing.
  • the height b 1 of the trunk 201 is less than the height b 2 of the portion of the junction in which the signals combine or divide, this height b 2 itself being less than the total height b 3 of the two branches 200.
  • FIG 8 illustrates the rear of the antenna 1, that is to say on the side opposite the front face from which the antenna elements 3 point.
  • a second network of dividers/combiners 6 in the plane E is intended to combine/divide the signals from the different blades 2, independently for each polarization.
  • This network 6 comprises a first LHCP half-network 6 for the first LHCP polarization and whose branches form a first comb intended to be connected to the blades 2 of first polarization.
  • a second half-array 6 RHCP for the second polarization RHCP comprises branches forming a second comb interposed between the first comb and intended to be connected to the blades 2 of second polarization.
  • the trunk of the first half-array forms the first LHCP port 7 of antenna 1 and the trunk of the first half-array forms the first RHCP port 7.
  • FIG. 9 illustrates one of the half-networks, for example the first half-network 6 LHCP .
  • it comprises 16 branches 60 0 to 60 15 forming the comb intended to connect to the trunk/port of the different blades 2.
  • the number of branches 60 depends of course on the number of blades 2.
  • Four levels of junctions 1 -à-2 61,62,63,64 in the plane E successively allow the signals of these different branches to be combined/divided into a common trunk 7 forming one of the two ports of the antenna.
  • the output of this trunk 7 is bent at 90° to facilitate connection to a waveguide or directly to the electronic circuit.
  • FIG. 10 schematically illustrates the tree structure of the junctions within each blade 2, the blade grouping together both the first divider/combiner network 4 and the 1-to-4 junctions 5 of the cell units 8 associated with this blade.
  • FIG. 11 schematically illustrates the tree structure of the junctions within the second network of dividers/combiners 6.
  • the antenna is advantageously produced in a monolithic manner, preferably by 3D printing of a metal or polymer core, then deposition of a conductive layer at least on the internal faces of the waveguides of the antenna.
  • the example above relates to an antenna comprising 16X16 antenna elements.
  • This number is non-limiting and the number of antenna elements can be any.
  • the number of lines is, however, preferably a multiple of 4 so that the antenna can be designed by stacking cell units comprising four antenna elements each.
  • This number is also advantageously a power of two so as to be able to produce a first network of dividers/combiners 4 with an equal number of junctions between each branch of this network and the trunk of the blade, thus more easily guaranteeing paths of isophase length to the different branches.
  • the number of antenna elements per branch, and therefore of blades 2 can be any. This number is, however, advantageously a power of two, so as to be able to produce a second network of dividers/combiners 6 with an equal number of junctions between each branch of this network and the ports 7 of the antenna, thus more easily guaranteeing paths of isophase length up to the different branches.
  • the antenna may include a mounting hole passing through the network of dividers in a direction perpendicular to the direction of signal transmission, and allowing it to be mounted by threading it around a cylindrical mounting bar. This solution makes it possible to easily adjust the orientation of the antenna by pivoting it around the bar.
