Abstract (en)

[origin: EP0557176A1] The invention relates to a feed device intended for an array of plate antennas with dual crossed polarisation and to an array employing such a device. The plate antennas (S) are fed via two completely separate lines. A first transmission line, of the three-plate type, consists of a track (T) and two earth planes (M, CP). A second line, of the microstrip type, comprises a track (R) and an earth plane (M). The unit is produced by metallising three printed circuits (CI1 to CI3); there are several variant embodiments. Application to the feeding of satellite receiving antennas having dual crossed polarisation. <IMAGE>
