Abstract
An antenna device that is placed adjacent to an antennafor receiving a high frequency signal and includes an impedance matching circuitand an amplifying circuitto which a DC control voltage is supplied from a demodulating devicethrough a feeder cablefor transmitting the high frequency signal to the demodulating device, wherein the DC control voltage is set to a value for adjusting a frequency characteristic of the impedance matching circuitwithin an allowable range corresponding to a received frequency. A small and inexpensive antenna device having a simple circuit configuration and good reception sensitivity is implemented.
