摘要

本文研究了一种具有增强轴向比(AR)带宽的紧凑单点馈电圆极化天线。采用寄生带和改进宽缝隙的几何结构相结合的方法提高了天线的圆极化性能。天线的总占地面积仅为$25\times 25\ \text{mm}^{2}$。采用该技术，通过CP工作频段，阻抗带宽$\vert \mathrm{S}_{11}\vert \leq-10$ dB为70％ (4.2 GHz ～ 9.05 GHz)， AR带宽$\leq 3\text{dB}$为48％ (5.4 GHz ～ 8.65 GHz)，平均实现增益为3.1 dBi。在$\pm z-$方向上观察到稳定的左CP和右CP双向辐射模式。

Single-Paint-Fed Broadband CP Antenna With Enhanced Axial Ratio

In this paper, a compact single-point-fed circularly polarized antenna with enhanced axial ratio (AR) bandwidth is investigated. A combination of parasitic strips and modified geometry of the wide-slot is used to improve circular polarization (CP) performance of the antenna. The total footprint of the antenna is only $25\times 25\ \text{mm}^{2}$. With the proposed technique, an impedance bandwidth $\vert \mathrm{S}_{11}\vert \leq-10$ dB of ~70-percent (4.2 GHz- 9.05 GHz), and AR bandwidth $\leq 3\text{dB}$ of 48-percent (5.4 GHz to 8.65 GHz) has been achieved with the average realized gain of 3.1 dBi through the CP operating band. A stable bidirectional radiation pattern with left hand CP and right hand CP in the $\pm z-$ direction is observed.
