摘要

GPS天线应该覆盖大部分天空，并能看到尽可能多的卫星。天线应具有宽辐射波束和低增益。天线必须在相关频率上匹配良好，并且是右圆极化。天线是GPS系统实现高定位精度和短捕获时间的关键因素。本文的目的是提出GPS天线的要求，并对不同类型的天线进行描述和比较。

Overview of GPS antennas

GPS antennas should cover most of the sky and see as much satellites as possible. The antenna should have a broad radiation beam and low gain. The antenna must be well-matched in the relevant frequencies and be Right Hand Circular Polarized. The key factor in GPS systems for high position accuracy and for short acquisition time is the antenna. It is the objective of this paper to present the requirements from GPS antennas and to describe and compare different antenna types.
