| 摘 要： | 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2.5 GHz和5.5 GHz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-10 dB阻抗带宽分别为低频部分10.4%(2.35~2.61 GHz),高频部分27.8%(4.96~6.46 GHz),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. |
