用于WLAN的双频反C形CPW馈电天线

一种用于WLAN的双频反C形CPW馈电天线

内容简介：提出了一种新颖的由共面波导（CPW）馈电的单极子双频天线。天线可分别在2．5GHz和5．5GHz频率上谐振。该天线由一个反C型单极子组成，如同一个缺了一角的环形单极子，结构简单。利用HFSS仿真得到的一10dB阻抗带宽分别为低频部分10．4％（2．35～2．61GHz），高频部分27．8％（4．96—6．46GHz），能够满足无线局域网（WLAN）的需要。同时天线的体积较小可以降低成本。

Abstract：A novel coplanar waveguide （CPW） -fed monopole antenna that resonates at 2. 5 GHz and 5.5 GHz, respectively, is proposed. The antenna comprises a circular-monopole with a corner cut and becomes an inverted-C monopole. The simulation results by HFSS show good dual-band operations with - 10 dB impedance bandwidths of 10. 4% and 27.8% at the two resonant frequencies, respectively, which cover the 2. 35 - 2. 61 GHz and 4. 96 6. 46 GHz. These cover the WLAN operating bands. In addition, the cost is reduced due to its small volume.
