摘要
A frequency stabilization circuit (25) includes four coiled conductors (L1 to L4), the first coiled conductor (L1) and the second coiled conductor (L2) are connected in series to each other, thereby configuring a first series circuit, the third coiled conductor (L3) and the fourth coiled conductor (L4) are connected in series to each other, thereby configuring a second series circuit, the first series circuit is connected between an antenna port and a power feeding port, and the second series circuit is connected between the antenna port and the ground. The first coiled conductor (L1) and the second coiled conductor (L2) are wound so that a first closed magnetic circuit (a loop indicated by a magnetic flux FP12) is configured, and the third coiled conductor (L3) and the fourth coiled conductor (L4) are wound so that a second closed magnetic circuit (a loop indicated by a magnetic flux FP34) is configured.
