<p>PROBLEM TO BE SOLVED: To make a radio communication device small-sized and light in weight in the radio communication device with a configuration in which diversity receiving is performed by a main antenna and a sub antenna and a battery is also charged by a non-contact system charging method. SOLUTION: An impedance element 19 is connected to a power incoming coil 12 operating as a power receiving part when it is charged according to a non-contact system, and a resonance circuit 20 is formed so that the coil 12 can resonate in 800 MHz band for radio communication of a high frequency. Because the coil 12 is used both as the power receiving part when a battery is charged and as a sub antenna for dedicated receiving to capture radio waves, it is possible to reduce the number of parts for sub antennas such as a dielectric printed antenna and a flat antenna which are needed in the conventional configuration to perform diversity receiving.</p> |
