摘　　要：本文提出一种新型的共面波导馈电的双极化宽带分集天线,采用MEM开关控制两个相互正交的宽缝隙结构分别接收相互垂直的极化信号。实验结果表明,该天线的两个单元同时工作时阻抗带宽可以达到4～18GHz(S11<-10dB),同时,在工作频带内具有良好的分集辐射特性。A novel wide-band dual-polarized CPW-fed antenna is proposed. Two orthogonal wide slots antenna element are employed to receive dual-polarized signal respectively. Measurement results show that the impedance bandwidth of the antenna reaches up to 4-18 GHz for S11 〈 - 10 dB. Also, due to differences in polarization and spatial location of the individual antenna element, efficient receiving performance for diversity signals is achieved.
