A New Design Principle of Active Receiving Antennas Applied with a High Impedance Amplifier-Diversity-Module in a Compact Multi-Band-Antenna-System on a Plastic Trunk Lid 2006-01-0480

In vehicles such as e.g. cabriolets, parts of the skin are made of plastics as e.g. the trunk lid. This enables the integration of a 4-antenna-FM-diversity system with an excellent quality of reception. As antenna elements for mobile FM- and TV-reception a novel ring wire structure with 2 switching elements is used. An advanced concept of high input impedance amplifiers leads to a satisfying effective antenna height. Since the antenna structure is only placed along the rim of the dielectric trunk lid there is space left inside the given area for additional low profile antennas for example for AM, GPS, SDARS, GSM and PCS.
