Abstract (en)
Elemental microwave antenna able to constitute one of the elements of an array, this antenna being capable of transmitting or receiving two waves with orthogonal polarisations. <??>It consists of a cavity (1) containing the two orthogonal excitation probes (4, 6) separated by a polarisation-selective obstacle (9), forming a short-circuit plane for the wave transmitted by the upper probe (6) and a "patch" for the wave transmitted by the lower probe (4). Another "patch" (13) is common to these two nested antennas. A third "patch" (15), which is polarisation-selective in the sense that it is transparent to the wave transmitted by the lower probe (4), can moreover be provided. <IMAGE>
