摘要

基于EBG的天线设计可以在地球同步卫星导航(GSN)系统天线中找到它的应用,因为它允许减少辐射元素的数量,同时保持所需的高指向性和圆极化。它们的使用将大大简化馈电网络,同时减少天线的质量和体积。本文提出了一种易于调谐到所需频率的双层EBG层。对该设计进行了优化,满足了广域增强系统(WAAS)在L1和L2频段的导航天线应用要求。

Multiband EBG navigation antenna
EBG superstrate based antenna designs can find its applications in Geosynchonous Satellite Navigation (GSN) System Antennas, since they allow to reduce the number of radiating elements while keeping the required high directivity and circular polarization. Their use will considerably simplify the feeding network and simultaneously reduce the antenna mass and volume. A dual layer EBG superstrate which can be easily tuned to the desired frequencies is presented in this paper. The design has been optimized to comply with the navigation antenna requirements of Wide Area Augmentation System (WAAS) application in L1 and L2 bands.
