Abstract

In this paper, a new wideband coplanar waveguide (CPW) rhomboid slot antenna by using conductor-backed coplanar waveguide (CBCPW) feeding, which works at 4.6 GHz with a relative impedance bandwidth of about 55.6 %, and a gain of more than 5.5dBi from 4 to 6 GHz, has been proposed, and the performance of a CPW circular slot antenna and a CPW rectangular slot antenna are also used for comparing with the proposed antenna. It is demonstrated that the CPW rhomboid slot antenna has wider impedance bandwidth, higher gain and better radiation pattern compared with the circular and rectangular slot antennas, meanwhile, low profile has also realized. The CPW rhomboid slot antenna with CBCPW feeding has been fabricated and measured, and the design has been verified.

摘要

本文提出了一种采用背腔共面波导（CBCPW）馈电的新型宽带共面波导（CPW）菱形缝隙天线，其工作频率为4.6GHz，相对阻抗带宽约为55.6%，在4至6GHz频段增益大于5.5dBi，同时还将CPW圆形缝隙天线和CPW矩形缝隙天线的性能与该天线进行了比较。结果表明，与圆形和矩形缝隙天线相比，CPW菱形缝隙天线具有更宽的阻抗带宽、更高的增益和更好的辐射方向图，同时也实现了低剖面。制作并测量了采用CBCPW馈电的CPW菱形缝隙天线，验证了设计的正确性。
