ANTENNA SYSTEM, AND TRANSMISSION/RECEPTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an antenna system capable of relaxing or avoiding interference caused by resonant points of antennas even when a plurality of coil antennas are adjacently disposed, and to provide a transmission/reception apparatus provided with the antenna system.

SOLUTION: The antenna system is provided with: a coil antenna 3; a capacitor 4 connected to the coil antenna 3 and comprising a resonance circuit together with the coil antenna 3; and an intermittent switch 5 for changing a resonant state of the resonance circuit. The capacitor 4 is connected to the coil antenna 3 in parallel or in series. The intermittent switch 5 is connected in parallel to the capacitor 4.
