A MODULAR PHASED-ARRAY ANTENNA

摘要

A modular phased-array antenna including a beam-forming network module, a patch array module, and a matching network module interconnecting the beam-forming network module and the patch array module. The beam- forming network includes suspended stripline passive hybrid and crossover elements configured in a Butler Matrix formation interconnected with transceiver antenna patches via the matching network module which in turn comprises suspended stripline phased-matched tracks and a plurality of oppositely polarised matching elements.
