ACTIVE DUAL-POLARIZATION MICROWAVE REFLECTOR, IN PARTICULAR FOR ELECTRONICALLY SCANNING ANTENNA

摘要

The invention concerns an active dual-polarization electronically scanning microwave reflector, adapted to be illuminated by a microwave source to form an antenna. The reflector comprises two interleaved waveguide arrays (21, 22), the base of each guide being closed by a phase-shifting circuit producing reflection and phase shift of the wave it receives, one array being designed to receive a polarization and the other array being designed to receive a polarization perpendicular to the former.
