A Wideband Antenna for Global Navigation Satellite System With Reduced Multipath Effect

This letter presents a wideband circularly polarized patch antenna for GPS/GLONASS/BEIDOU/GALILEO systems with reduced multipath effect. The proposed antenna includes four L-probe feeds that are connected the feed network, two circular patches, and a choke ring base. The choke ring base is designed...

Zusammenfassung:This letter presents a wideband circularly polarized patch antenna for GPS/GLONASS/BEIDOU/GALILEO systems with reduced multipath effect. The proposed antenna includes four L-probe feeds that are connected the feed network, two circular patches, and a choke ring base. The choke ring base is designed to reduce the multipath effect of the receiver. Experiment results indicate that the bandwidth of the antenna is 50.9% under S 11
