<p>Provided is a radio communication device which can prevent degradation of an antenna by controlling the VSWR and the current phase f antennas arranged adjacent to one another. In this device, an antenna (201) has a predetermined resonance frequency. A breaking circuit (203) is connected to the antenna (201) in parallel to a rectification circuit (205) so as to shut off the resonance frequency of the antenna (201). A terminating circuit (204) electrically terminates the output side of the breaking circuit (203). An antenna (207) is arranged in the vicinity of the antenna (201) and has a resonance frequency different from a resonance frequency of the antenna (201). A breaking circuit (209) is connected to the antenna (207) in parallel to a rectification circuit (211) and shuts off the resonance frequency of the antenna (207). A terminating circuit (210) terminates the output side of the breaking circuit (209).</p>
