Abstract
A radiating or receiving element for orthogonally polarized high-frequency signals comprises, on both sides of a first layer having a first cavity, first and second perpendicular high-frequency transmission lines and at the other side of the transmission lines a second layer having a second cavity and a third layer having a third cavity facing the other two cavities but short-circuited so as to form a reflecting plane, the transmission lines being constituted by symmetrical slots and conducting strips, which are provided in the median plane of these lines and whose ends project into the cavities to form exciting probes whose lengths are different and chosen such that for any predetermined thickness of the first layer, the pairs of values: lengths of the end of a probe/distance of the probe to the sole reflecting plane correspond to an experimentally maximum or nearly maximum coupling between each of the probes and the propagation medium.
