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
