Abstract

PURPOSE:To enhance the antenna efficiency by inserting the inductance, which is made to resonate to the general sum of the radiant capacity the antenna features with the frequency higher than the upper limit of the reception band and the electrostatic capacity between the antenna and the car body, between the antenna and the feeder. CONSTITUTION:The radiant impedance of the antenna at the AM band is composed of the capacity of 15pF and the resistance of 80OMEGA. The feeder features the capacity of 65pF. Then inductance L is inserted between the antenna and the feeder, and as a result the resistance value of the impedance can be increased when viewed from the input end of the receiver.
