Multi-system automotive antenna for mobile satellite communications applications

This paper presents two multi-system antennas designed for automotive mobile satellite communication applications. The antennas are optimized for the new European S-band mobile satellite systems and in addition they include also the capabilities for GPS and GSM/UMTS bands. The first model implements an S-band Receive-Only radiating element for broadcasting applications while the second contains also an S-band transmit element allowing interactive services via satellite. The achieved structures can be easily installed on cars or integrated in plastic structures of the vehicles. The details of the design of the antennas and a summary of their performances are described.
