摘要

提出了一种结构简单、结构紧凑、具有圆弧缺陷贴片面的矩形微带天线，可以有效地抑制交叉极化辐射，提高极化纯度。对所提出的天线进行了系统的研究，并进行了理论论证。仿真和实验结果也支持了这一想法。所提出的结构简单，易于制造。在共极化(CP)辐射中发现了约25 dB的XP辐射隔离。对缺陷尺寸对天线辐射性能的影响进行了全面的研究和验证。探索新结构的目的是在不改变高阶正交共振主模场构型的情况下消除高阶正交共振。

Rectangular microstrip antenna with defected patch surface for improved polarization purity

A simple and compact rectangular microstrip antenna with circular arc defected patch surface is proposed for significant suppression of cross polarized (XP) radiation and improved polarization purity. The proposed antenna has been studied methodically with theoretical justifications. Simulation and experimental results are also presented in support of the present idea. The proposed structure is simple and easy to fabricate. Around 25 dB of XP radiation isolation from co polarized (CP) radiation is revealed. The effect of dimensions of the defect on the radiation performance of the proposed antenna has been thoroughly examined and verified. The exploration of the new structure is carried out with a view to eliminate higher order orthogonal resonance without altering its dominant mode field configuration.
