摘要
提出了一种新颖的共面波导馈电单极天线,"△"形辐射单元馈刻在介质板上,由同一面的共面波导传输线馈电.对此种天线进行了理论分析,加工并测试了一个天线单元,理论值和实验值吻合较好,验证了设计的可行性,实测阻抗带宽达到111 8%(VSWR小于等于2),天线工作频率为0 788～2 787GHz,此种天线适合于通信领域的应用.
A novel arrow-shaped 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. The antenna is analyzed numerically, fabricated and tested. The measured results are given, showing a 111.8% bandwidth for the voltage standing wave ratio(VSWR) of 2:1 covering the 0.788～(2.787GHz) frequency range. The numerical results agree well with the experimental ones. The proposed antenna can be used conveniently in broadband communications.
