摘要

提出了一种宽带圆极化(CP)缝隙天线的设计方法。缝隙天线的CP辐射是由微带线的近距离耦合激发的。为了获得较宽的CP带宽，对CP波段中包含的三个CP模式进行激励。结果表明，在阻抗带宽为64% (2.96 GHz-5.75 GHz)的情况下，该天线可提供56% (3.17 GHz-5.65 GHz)的CP工作带宽。

The design and analysis on broadband circularly-polarized slot antenna

A design of a broadband circularly-polarized (CP) slot antenna is proposed in this paper. The CP radiation of the slot antenna is excited by the proximity coupling of a microstrip line. To obtain a broad CP bandwidth, three CP modes contained in the CP band are excited. The results show that the proposed antenna can provide a CP operating bandwidth of 56% (3.17 GHz-5.65 GHz) within an impedance bandwidth of 64% (2.96 GHz-5.75 GHz).
