1. A radio communication device that includes a radio communication unit transmitting simultaneously a plurality of communication data series using a same frequency band to a receiving device through a transmitting antenna unit including a plurality of transmitting antennas, comprising:

  • an antenna selector configured to perform antenna selection processing when a communication quality degrades below a predetermined threshold in a radio communication channel between the radio communication device and the receiving device receiving simultaneously the plurality of communication data series and separating the plurality of communication data series into individual communication data series, the antenna selection processing performed by selecting, from among the plurality of transmitting antennas forming the transmitting antenna unit, such transmitting antennas that a distance between the transmitting antennas is shorter than before the communication quality degrades below the predetermined threshold, whereinthe radio communication unit transmits the communication data series through the transmitting antennas selected by the antenna selector.
