Multimode Multi-Constellation GNSS Antenna

This paper demonstrates a multimode Multi-Constellation GNSS (Global Navigation Satellite System) Antenna solution for automotive applications. In designing a GNSS Antenna to cover global requirements, there are requirements to be considered in order to support multiple navigation satellite constellations. In addition to GPS, the GLONASS constellation is required to support ERA-GLONASS in Russia, the Galileo constellation is required to support eCall in Europe. Also, there is the BeiDou constellation being deployed by China. Given the constellations have varying bandwidths and carrier frequencies, it is a challenge to design and integrate an antenna solution to support global coverage. In this paper, a single multimode multi-band patch antenna is designed and result shows the potential applications.
