MULTI-CHANNEL ANTENNA DEVOICE

摘要

A multi-channel antenna device of the present invention comprises a feed network; a fundamental mode radiator to form a basic mode main beam pattern having one or two orthogonal polarization based on two orthogonal inputs transferred through the feed network; and a higher-order mode emitter to form a higher-order mode conical beam pattern having one or two orthogonal polarization based on distinct two orthogonal inputs transferred through the feed network.
