Patent ID: 7564416

Claim:
An antenna system for radio reception, being disposed in a motor vehicle window comprising: a) an imprinted heating field formed in said motor vehicle window, comprising a plurality of heating conductors and a plurality of bus bars; b) a plurality of antenna connection contacts; c) at least one antenna formed by connecting said imprinted heating field to at least one antenna connection contact of said plurality of antenna connection contacts via at least one conductor of said plurality of heating conductors; d) a rod antenna mounted on an outer side of the motor vehicle; e) an electrical through coupling, coupled at one end to said rod antenna, wherein reception signals are conveyed along said electrical through coupling into an interior of the motor vehicle for reception of signals both for relatively low frequencies and above a high frequency range, f) an antenna connection point region having a diameter that is smaller than 1/15 of a wavelength in said high frequency range, wherein said at least one antenna connection contact, and said at least one additional connection contact are disposed within said antenna connection point region; g) a ground connection to the motor vehicle body disposed in said antenna connection point region; h) an antenna module disposed within said antenna connection point region and within an interior region of the motor vehicle, said antenna module comprising electronic components including signal amplifiers for signal amplification in both said relatively low frequency and above said high frequency range, for reception signals from said at least one antenna connection contact and said at least one additional antenna connection contact; i) a plurality of connection lines for allowing said reception signals from said at least one antenna connection contact and said at least one additional antenna connection contact to flow to said antenna module, wherein said reception signals are also passed to said ground connection; and j) a shielded HF line for passing output signals in both said relatively low frequency range and said relatively high frequency range to said antenna module.
