Tri-band Multi-Constellation GNSS Antenna

This paper demonstrates a Tri band Multi-Constellation GNSS (Global Navigation Satellite System) Antenna solution for automotive applications. A single GNSS receive antenna that can be used in all global markets and support Tri-band operation is highly desirable for automotive applications. GNSS includes GPS, GLONASS, Galileo, and Beidou satellite constellations Each of these constellations use different bandwidths and carrier frequencies, thus making it is a challenge to design a single antenna solution to support global application. In this paper, a single Tri band multi-constellation patch antenna is designed, and simulation results are utilized to show the antenna design's capabilities.
