摘要

本文介绍了加拿大渥太华国防研究与发展部开发的几种用于GPS/GNSS应用的宽带圆极化天线。采用不同的技术设计了三种辐射元件。在整个GNSS频段(1.15 GHz至1.62 GHz)内，它们在阻抗匹配、覆盖、增益和轴比方面都表现出非常好的性能。介绍了它们的特点，并在EM性能和尺寸方面进行了比较。

Wideband circularly polarized antenna elements for GPS/GNSS applications developed at DRDC Ottawa

This paper presents several wideband circularly polarized antennas for GPS/GNSS applications that have been developed at Defense Research & Development Canada – Ottawa. Three radiating elements were designed using different technologies. All of them exhibit very good performance in terms of impedance matching, coverage, gain and axial ratio over the entire GNSS frequency band (1.15 GHz to 1.62 GHz). Their characteristics are presented and compared in terms of EM performance and size.
