Abstract

The paper deals with a method for designing a patch antenna with circular polarization to be resonant at 9.5GHz (X-band) for RADAR applications. It aims at overcoming the drawbacks of a single patch antenna. The existing single patch antenna resulted in a gain of 6dB. To improve the gain further, the proposed model consists of a synchronous array of 4 linear elements designed to produce circular polarization at the desired frequency. The simulation of the array antenna resulted in a gain of 8dB with an axial ratio of 2.9dB. The return loss of the patch antenna was found to be −20dB at 9.5GHz.

同轴馈电同步圆极化微带贴片天线阵列的设计

本文研究了一种用于雷达的9.5GHz (x波段)圆极化贴片天线的设计方法。它旨在克服单个贴片天线的缺点。现有的单贴片天线的增益为6dB。为了进一步提高增益，该模型由一个由4个线性元件组成的同步阵列组成，该阵列设计用于在所需频率产生圆极化。仿真结果表明，阵列天线的增益为8dB，轴向比为2.9dB。在9.5GHz时，贴片天线的回波损耗为−20dB。
