High-Performance Universal GNSS Antenna Based on SMM Antenna Technology

Abstract

A class of high-performance low-cost GNSS antennas that cover all three GNSS services (GPS/GLONASS/Galileo) is presented. The designs are based on the ultra-wideband SMM antenna, which has a phase center inherently more stable with angular and frequency variations than other antenna types. The antenna is low-cost and platform conformable. Size reduction using the slow-wave antenna technology and the magneto-dielectric antenna technology is discussed.
