Abstract

In this paper, the design consideration for right-hand (clockwise) and left-hand (counterclockwise) circularly polarized microstrip slot antennas are presented. The circularly polarized antenna consists of two right angle slot antennas that is two orthogonal modes in phase quadrature or an array of linearly polarized slot with proper orientations and phases. This antenna can generate circular polarization by radiating orthogonal field components from two slots with equal amplitude but in phase quadrature. Two orientations for circularly polarized are investigated in this paper from simulation and measurement results are shown at resonance frequency 2.45 GHz on return loss, VSWR and radiation patterns.
用于IEEE 802.11b/g无线局域网的圆极化直角槽天线
本文介绍了右(顺时针)和左(逆时针)圆极化微带槽天线的设计考虑。圆极化天线由两个正交相位正交的直角槽天线或方向和相位合适的线极化槽阵列组成。该天线通过从两个振幅相等但相位正交的槽中发射正交场分量来产生圆极化。本文从仿真和测量的角度对圆极化的两种取向进行了研究,得到了在2.45 GHz谐振频率下圆极化的回波损耗、驻波比和辐射方向图。
