摘要

提出了一种宽带双频工作的缝载圆形微带天线的设计方案，并进行了实验研究。该天线的两个工作波段具有相同的极化平面，并且具有相似的辐射特性。所提出的双频设计还可以为两个工作频带的中心频率的频率比提供约1.28 ~ 1.59的可调谐范围。对于本文研究的构建原型，获得了较低频段约7.0%至9.6%的宽阻抗带宽和较高频段约16.1%至24.4%的宽阻抗带宽。

Experimental study of broadband dual-frequency circular patch antennas

A novel design of a slot-loaded circular microstrip antenna with broadband dual-frequency operation is proposed and experimentally studied. The two operating bands of the proposed antenna are of the same polarization planes and also have similar radiation characteristics. The proposed dual-frequency design can also provide a tunable range of about 1.28 to 1.59 for the frequency ratio of the center frequencies of the two operating bands. For constructed prototypes studied here, wide impedance bandwidths of about 7.0 to 9.6 % for the lower band and 16.1 to 24.4 % for the higher band are obtained.
