摘要

提出了一种适用于WiMax和WLAN系统的双频双极化贴片天线。在3.6 GHz和5.2 GHz分别可以实现7.5%和9.6%的阻抗带宽。利用不对称u型槽产生3.6 GHz的圆极化正交模，轴比带宽为3dB，为0.7%，在贴片上切割对称u型槽获得线性极化。在CP和LP波段同时获得更高的增益。低频段和高频段的峰值增益分别为8.5 dBi和8.6 dBi。给出了天线的仿真结果并进行了讨论。

Single-fed dual-band dual-polarized U-slot patch antenna

A dual-band dual-polarized patch antenna is proposed for WiMax and WLAN systems. Impedance bandwidths of 7.5% and 9.6% can be achieved at 3.6 GHz and 5.2 GHz, respectively. The asymmetrical U-slot has been used to generate the orthogonal modes for circular polarization at 3.6 GHz with a 3dB axial ratio bandwidth of 0.7%, and the linear polarization is obtained by cutting a symmetrical U-slot on the patch. Higher gains at both CP and LP bands are obtained simultaneously. The peak gains in lower and higher bands are 8.5 dBic and 8.6 dBi, respectively. The simulated results of the antenna have been presented and discussed.
