摘要： A glass antenna for an automobile uses a coil connected directly to a bus for defogging heaters as an FM subsidiary antenna and a T-shaped impedance matching circuit to provide a monotone change of impedance within the FM frequency band. A reverse T-shaped FM main antenna is employed in conjunction with the FM subsidiary antenna to provide a diversity system to enhance receiving sensitivity in entire directions. The T-shaped matching circuit comprises at least two varactor diodes each applied to a channel selection voltage to match the FM antenna impedance with that of the FM receiver including that of the transmission cable.

摘要： A glass antenna system for an automobile comprises a T-shaped or pi-shaped dynamic impedance matching circuit. Another system comprises an integrated circuit consisting of T-shaped FM and AM matching circuits each connected to a common cable. The T-shaped or pi-shaped matching circuit comprises at least two varactor diodes each applied to a channel selection voltage to match the FM antenna impedance with that of the FM receiver including that of the transmission cable.
