Abstract
An automobile antenna including a high frequency signal processing unit provided near an antenna where the processing unit only tunes in a designated frequency band and amplifies it and further detects the amplified signal. The high frequency signal processing unit also adjusts the tuned frequency band at the high frequency signal processing unit based upon a tracking signal sent from an automobile receiver. Since the high frequency signal processing unit is provided adjacent to antennas, that is, near a glass antenna or mounted on an antenna mast, a loss which occur between the antenna and the receiver can be fully compensated for and noise interference can be avoided.
