一种新型三频圆极化微带天线的研究
内容简介:本文设计了一种三频圆极化微带贴片天线,天线能够同时工作在GPS L1、L2波段和GLONASS波段。天线将两层层叠辐射贴片和馈电网络集成在一起,层叠结构保证了天线的紧凑。双馈电结构与圆极化馈电网络保证了天线具有良好的阻抗带宽和圆极化特性。用HFSS软件对天线进行仿真、优化。文中给出了天线的详细设计及实测结果,实测结果表明该天线性能良好。
Abstract:A new triple-band circularly polarized microstrip antenna is presented in this paper.The proposed antenna can operate at GPS L1,L2 band and GLONASS band simultaneously.The antenna integrates two-layer stacked radiate patches with feeding network.The stacked structure carries out compactness of the antenna.The dual-feed structure and circularly polarized feeding network guarantee good impendance bandwidth and good circular polarization performance.This antenna is analyzed and optimized by the software HFSS.Details of the antenna design and experimental results are presented and discussed in the paper.The measured results show good performance of the antenna.
