<p><P>PROBLEM TO BE SOLVED: To provide a base station apparatus provided with two systems of wireless communication sections or over capable of carrying out normal reception without destroying a receiver side wireless communication section and saturating the receiver wireless communication section even when the wireless communication sections are asynchronously in operation and make communication. <P>SOLUTION: A hybrid coupler 102 which converts an input signal into two signals with a phase difference of 90 degrees from each other and provides an output of them is interposed between wireless apparatuses 103a, 103b and antenna systems 101a, 101b so that the powers leaked between the antenna systems 101a, 101b are cancelled with each other through the hybrid coupler 102. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
