<P>PROBLEM TO BE SOLVED: To use a shared antenna coping with a plurality of communication systems and to perform communications of the respective communication systems together. <P>SOLUTION: First of all, a wireless LAN including a diversity function is set as a communication system of high priority for antenna selection, and a Bluetooth(R) is set as a communication system of low priority for antenna selection. When both a LAN switch and a BT switch are operated and operational states of a communication function by the wireless LAN and a communication function by the Bluetooth(R) are turned on, a switch 23 connects one of antennas 21, 22 with an RF part 24 for LAN in accordance with the ambient communication environment. When the connection is made, an antenna to be connected with an RF part 26 for BT becomes an antenna not to be connected with the RF part 24 for LAN. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
