Abstract

For the reception of Satellite Digital Audio Radio Services (SDARS) and Global Positioning Systems (GPS) transmitted via satellite an invisible antenna combination embedded in the roof of a car is presented. Without changing the surface of the vehicle the antenna combination can be completely embedded in a metal cavity and covered by a thick dielectric part of the roof. The measurement results show a high efficiency and a large bandwidth which exceeds the necessary bandwidth significantly for both services. The antenna combination offers a radiation pattern which is tailored to the reception of SDARS signals transmitted via highly-elliptical-orbit (HEO) satellites, geostationary earth orbit (GEO) satellites and terrestrial repeaters and for GPS signals transmitted via medium earth orbit (MEO) satellites. Although the antennas are mounted in such a small mounting volume, the antennas are decoupled optimally.
