Integrated Backlite Antenna System for AM/FM and TV Broadcast Reception and for Mobile Telephone

With increasing number of mobile radio services (AM/FM/TV/phone/weatherband/remote control) the number of antennas required increases. For better quality of FM-reception antenna diversity must be applied. Mobile TV reception is almost impossible without antenna diversity. Therefore for some services more than one antenna is required.

In the paper a multiantenna backlite system is presented. The antenna structures of the active receiving antennas are printed on the glass, partly simultaneously used as heaters. The phone antenna is mounted “on glass” in the middle of the screen at the upper edge of the window far away from passers-by. The electromagnetic field in the car is reduced by a shielding additionally printed on the screen.
