摘要

本文介绍了一种用于全球导航卫星系统（GNSS）的紧凑型低剖面天线，特别是针对三频全球定位系统（GPS）覆盖范围进行了优化。利用基于超材料的电磁带隙结构（MTM-EBG）开发了一种双频天线，可覆盖 GPS L1、L2 和 L5 频段以及全球导航卫星系统的大部分频谱。该贴片天线是在地平面上方的单个基片的两面上制作的，基片采用 3-D 打印聚乳酸（PLA）隔板，制作简单。仿真和测量结果表明，该天线在匹配、增益、图案形状和轴向比方面性能良好，是现代高精度多频带和多系统 GPS/GNSS 接收器的理想选择。

Compact Fully Printed GPS/GNSS Antenna Using Embedded MTM-EBGs

A compact and low-profile antenna for global navigation satellite systems (GNSSs), with particular optimization for triband Global Positioning System (GPS) coverage, is presented. A dual-band antenna is developed with the use of metamaterial-based electromagnetic bandgap structures (MTM-EBGs) that covers GPS L1, L2, and L5 bands and a majority of the GNSS spectrum. The patch antenna is fabricated on two sides of a single substrate sheet above a ground plane, with a 3-D printed polylactic acid (PLA) substrate spacer for simple fabrication. The antenna is fed by a wideband and planar feed network below the ground plane, and simulation and measurement results show good performance in terms of matching, gain, pattern shape, and axial ratio, demonstrating that this antenna is an excellent candidate for use with modern high-accuracy multiband and multisystem GPS/GNSS receivers.
