摘要
提出了一种在贴片上加载U形槽并应用双短路针调谐的双频微带天线.该天线应用于无线局域网IEEE802.11b和IEEE802.11a系统中.通过在贴片天线上加载U形槽产生两个谐振频率,调节两个对称的短路钉使其工作在无线局域网的频带内,增大了天线带宽.仿真实验得到该天线的两个谐振频率分别为2.4 GHz和5.2 GHz,其低频和高频的相对带宽分别为4.2%和5%,可充分满足无线局域网的要求.
This paper discussed a microstrip antenna with a U-sl- ot on the patch and loaded with double shorted posts.This an- tenna satisfies the requirements of wireless local area network (WLAN)IEEE802.11b and IEEE802.11a applications.The dual-band antenna was based on the patch with a U-slot.The two resonance frequencies could be easily turned to satisfy the requirements of wireless local-area network(WLAN)by adjust- ing the position of the double shorted posts,and the bandwidth was enhanced using the double shorted post.Simulation results show that the two resonant frequencies are 2.4 GHz and 5.2 GHz,and the relative bandwidths of low frequencies and high frequencies are 4.2% and 5%,and it can meet the require- ments of the WLAN applications,dual-band microstrip antenna; U-slot;double shorted posts,wireless local-area network (WLAN)
