る受信用アンテナ装置。In a receiving antenna device comprising a first antenna tuned to a low frequency band, a second antenna tuned to a high frequency band, and a feed line whose input side is connected to each antenna and whose output side is connected to a receiver. , a switching circuit for switching the connection between the feed line and the first and second antennas is provided between the first and second antennas and the input side of the feed line, and a switching circuit is provided between the receiver and the feed line. A detection circuit is provided between the output side of the receiver and the receiver to detect that the receiver selects either the low frequency band or the high frequency band and outputs a DC signal,
A capacitor is provided between the receiver and the output side of the feeder line to allow a received signal from the feeder line to be input to the receiver, and a capacitor is provided between the receiver and the output side of the feeder line. A receiving antenna device comprising a coil that allows a DC signal from the detection circuit to be applied to the switching circuit via the feeder line.
