摘要

本文提出了一种在高阻抗表面(HIS)衬底上设计一种紧凑的非对称分形边界微带贴片天线，以产生圆极化(cp)。将方形贴片天线的侧面分别替换为x轴和y轴上的不对称半圆形分形曲线，可以实现尺寸紧凑的圆极化辐射。一个HIS夹在这个补丁和地平面之间。仿真结果表明，该天线的10db回波损耗带宽为57.26%，3db轴比带宽为14%。

HIS based asymmetrical fractal boundary microstrip antenna

This paper proposes design of a compact, asymmetrical fractal boundary microstrip patch antenna on high impedance surface (HIS) substrate to result in circular polarization (cp). The circular polarization radiation with compact size can be achieved by replacing sides of the square patch antenna with asymmetrical semi circle fractal curves along x and y axes respectively. A HIS is sandwiched between this patch and the ground plane. The 10-dB return loss bandwidth and 3-dB axial ratio bandwidth for proposed antenna are observed to be 57.26% and 14% respectively from simulations.
