<p><P>PROBLEM TO BE SOLVED: To reduce the interference between wireless machines, especially the interference between antennas, when a mobile communication terminal is equipped with two wireless machines which can receive and transmit simultaneously, and to prevent the degradation of radio properties due to interference. <P>SOLUTION: In a housing 500, a printed board 503 mounted with a first transceiver antenna 501, etc. and a printed board 504 mounted with a second transceiver antenna 502, etc. are arranged separately as different boards. By arranging the boards separately as different boards, the ground patterns of the first and second wireless machines can be separated physically. Consequently, a path of current flowing on the ground pattern between the first and second wireless machines can be cut, resulting in reduction of electric wave interference. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
