Abstract

In this paper, a single-feed arrow-shaped circularly polarized (CP) antenna is presented for GNSS application. Two orthogonally placed dipoles connected by phase delay lines are printed on both sides of a substrate to realize circular polarization. Further, an unbalanced slotted artificial magnetic conductor (AMC) is proposed to reduce profile of the antenna, enhance impedance bandwidth and CP bandwidth. Simulation results demonstrate the proposed antenna has a wide impedance matching band from 1.12GHz to 1.62GHz (36.4%), and a wide 3-dB axial ratio (AR) band from 1.17GHz to 1.577GHz (29.6%), which can cover B1, B2, B3 of BDS and L1, L2, L5 of GPS.

一种用于GNSS的单馈不平衡开槽人工磁导体箭头形圆极化天线

本文提出了一种用于GNSS的单馈矢状圆极化天线。在衬底的两侧印刷两个由相位延迟线连接的正交放置的偶极子，以实现圆极化。在此基础上，提出了一种非平衡开槽人工磁导体(AMC)来减小天线轮廓，提高阻抗带宽和CP带宽。仿真结果表明，该天线具有1.12GHz ~ 1.62GHz的宽阻抗匹配带(36.4%)和1.17GHz ~ 1.577GHz的宽3db轴比(AR)带(29.6%)，可覆盖BDS的B1、B2、B3和GPS的L1、L2、L5。
