System for motor vehicle with high frequency transmitter, receiver uses electrical leads in vehicle connected to receiver via coupling element containing bandpass filter as antenna

摘要

The system has at least one HF transmitter (2) associated with the vehicle, a receiver (6) with an HF input (14) and an antenna (4) connected to the receiver's HF input. Electrically conducting leads in the vehicle connected to the receiver via a coupling element are used as the antenna. The coupling element contains a bandpass filter that passes at least one HF signal transmitted by the transmitter.
