Automobile active receiving antenna

An active receiving broadcast band antenna for an automobile radio receiver of amplitude and frequency modulated signals having a common feeder, comprising:

• an antenna body mounted within the automobile interior;
• a bandpass filter having an input circuit including a capacitor, said capacitor comprising a metal member insulated from the automobile body and arranged in close vicinity to the automobile windshield and a structural member of said automobile body, said bandpass filter being included within said antenna body;
• a frequency-modulated signal amplifier positioned within said antenna body having an input connected to said bandpass filter and having an output;
• a power supply circuit for said frequency-modulated signal amplifier;
• a frequency correcting network positioned within said antenna body;
• an amplitude-modulated signal amplifier positioned within said antenna body and having an input connected to said bandpass filter via said frequency correcting network and an output;
• a power supply circuit for said amplitude-modulated signal amplifier;
• an interference filter connected to said power supply circuits of said frequency-modulated and amplitude-modulated signal amplifiers;
• and a frequency separation filter, said outputs of said frequency-modulated and amplitude-modulated signal amplifiers being connected to said common feeder of said radio receiver via said frequency separation filter.
