摘要

提出了一种可感知重构圆极化微带贴片天线，由于两个方形贴片的差异，在两个略有不同的频率下产生两个正交的线极化，两个贴片由一条馈线激励，产生圆极化(CP)的90°相位差。本文提出的天线可以通过在馈线上附加一个短段来在两个极化之间切换。即右手CP (RHCP)和左手CP (LHCP)。天线工作在2.56 GHz的RHCP和2.54 GHz的LHCP。在每个工作频率下，天线的阻抗匹配特性和轴向比(AR)都是可以接受的。

Sense Reconfigurable Circularly Polarized Microstrip Patch Antenna Design

A sense reconfigurable circularly polarized microstrip patch antenna is proposed, because a difference of the two square patches, two orthogonal line polarizations will be generated at two slightly different frequencies, and the two patches are excited by a single feedline to produce a 90° phase difference for circular polarization (CP). The presented antenna in this paper is able to switch between two polarizations by attaching a stub along the feedline. That is, right-hand CP (RHCP) and left-hand CP (LHCP). The antenna works at 2.56 GHz for RHCP and 2.54 GHz for LHCP. The impedance matching characteristic and the axial ratio (AR) of the antenna are acceptable at each operation frequency.
