A compact satellite antenna module for GPS, Galileo, GLONASS, BeiDou and SDARS in automotive application

A new design concept of a compact satellite antenna module for automotive application is presented, enabling mobile reception of all common navigation systems, e.g. GPS in L1&L2 bands, Galileo, GLONASS, BeiDou, as well as reception of satellite digital audio radio service (SDARS). A new design concept allows easy fabrication in combination with high reception properties. The performance of the antenna module, fulfilment of the requirements of car manufacturers and service providers is proven by simulated and measured results, showing the high realized gain for circular polarization, efficiency, matching and decoupling against terrestrial interferers.
