摘　　要：本文介绍了1种新型的,工作在WLAN双频带的滤波天线,该天线由双频天线和滤波馈电网络组成。其中,天线的双频辐射特性是由缝隙加载实现的,双频滤波特性是开口谐振环加载谐振枝节构成的三阶滤波器获得的。经测试,该双频天线可以工作在WLAN的2.4GHz/5.3GHz频段,具有较为良好的滤波特性。从结果来看,该天线是未来4G与5G信号并存时,WLAN双频段天线的合格候选。This communication presents a new type of dual-band filtering antenna for WLAN applications,which is composed of a dual-band antenna and a filter feed network.Among them,the dual-frequency radiation characteristic of the antenna is realized by slot loading,and the dual-frequency filtering characteristic is obtained by a third-order filter composed of resonant branches loaded by an open resonant ring.The test results show that the dual-band antenna can work in the 2.4GHz/5.3GHz frequency band of WLAN,and has good filtering characteristics.According to the results,this antenna is a qualified candidate for WLAN dual-band antenna when 4G and 5G signals coexist in the future.
