Abstract

The paper discusses a simple rectangular microstrip patch antenna modified to attain high gain with low radar cross section (RCS). This is achieved by incorporating a checkerboard comprising of an artificial magnetic conductor (AMC) and polarization conversion metasurface (PCM) unit cells. The unit cells are arranged around the patch antenna, retaining the single-layer property, and successfully achieving low RCS along with appreciable gain enhancement. Measured results indicate an RCS reduction of 29.84 dB for x- polarization and 30.46 dB for y- polarization, and a gain enhancement of 3.73 dBi at 5.5 GHz with respect to a reference microstrip patch antenna. Prototypes of the antennas are fabricated and measured, showing strong agreement between experimental results and simulations.

一种用于无线通信的低rcs高增益微带贴片天线

本文讨论了一种简单的矩形微带贴片天线的改进，以获得高增益和低雷达截面（RCS）。这是通过结合由人工磁性导体（AMC）和极化转换超表面（PCM）单元组成的棋盘来实现的。单元格排列在贴片天线周围，保留了单层特性，并成功地实现了低RCS以及明显的增益增强。测量结果表明，相对于参考微带贴片天线，x极化时RCS降低29.84 dB， y极化时RCS降低30.46 dB， 5.5 GHz时增益提高3.73 dBi。制作并测量了天线的原型，实验结果与模拟结果非常吻合。
