ABSTRACT:
A first inductance element is series-connected into a reception signal path of an antenna circuit between an antenna element and a receiver. A second inductance element is arranged to connect the antenna circuit to ground. These inductance elements series- and parallel-resonate with a ground stray capacitance of the antenna circuit including a feeder cable, so that reduction of gain of the reception system due to the stray capacitance is improved. A damping resistor is coupled to the second inductance element. The system has high reception sensitivity over a wide reception range with eliminating use of a pre-amplifier.
