要： 本文提出了一种新颖的共面波导馈电单极天线，在矩形辐射单元上蚀刻出一条缝，由同一面的
CPW 传输线馈电。采用商用 Ansoft HFSS 仿真软件对天线进行仿真设计，反射损耗小于-10dB 时得到了 80% 的阻抗带宽特性，工作频带为 1.25 GHz 到 2.95 GHz，适合于宽带或多频无线通信领域。 关键词： 单极天线；共面波导；宽带天线

Abstract:
A novel monopole antenna with a coplanar waveguide (CPW) feed line is presented. The element and the feed
line are etched on the same side of a substrate, and a rectangular slit is etched on the radiation patch. The antenna is simulated by commercial EDA software Ansoft HFSS, and a 80% bandwidth is achieved for return loss less than
