工作于2.4GHz/5.2GHz双频段微带缝隙天线的设计

摘要

设计了一款可应用于WLAN无线通信设备上的新型结构缝隙天线,该天线采用在贴片上开槽加载和微带线馈电等方法使其可工作在WLAN的2.4 GHz/5.2 GHz双频段上.通过高频仿真软件HFSS对天线进行的仿真结果比较理想,实测结果表明该天线覆盖了WLAN所需要的频率带宽为2.400 0～2.483 6 GHz和5.15～5.35 GHz.%In this paper,a novel microstrip slot antenna which adapt to WLAN wireless equipment is designed. Double-band capabilities are realized by using a channel-cutting and fed microtrip within the patch. The two central frequencies lie in the WLAN * s 2.4 GHz and 5.2 GHz. A fairly ideal results are got by simulating on the software HFSS. The actual measurement results show that the antenna has a good performance on the working frequency 2.400 0 - 2.483 6 GHz and 5.15 ~ 5.35 GHz.
