Abstract

The antenna has a primary source, formed by a horn (1), supplying a network of radiant sources (10) each with two radiant slits containing branches (11-14) in cross polarization. An electronically controlled reciprocal phase-shifter (5) is connected to the branches (12, 14) for each source. The primary source emits electromagnetic waves with arbitrary polarization and/or receives waves with multiple polarization.
