<P>PROBLEM TO BE SOLVED: To evade antenna performance degradation due to unnecessary resonance of other devices while minimizing influence on an antenna itself, and to contribute to miniaturization of a portable terminal. <P>SOLUTION: A device 2 is connected to a main substrate 1 through a connection pattern 3 including a substrate pattern and an FPC pattern. The connection pattern 3 is adjusted so as not to be the length of λ/2×N (N:integer) of a portable terminal operating frequency. When a metal device 2 is resonating, a length L of the connection pattern 3 including the substrate pattern and the FPC pattern is turned to λ/2×N (N:integer) of a desired operating frequency. Then, the length L of the connection pattern 3 is adjusted so as not to be λ/2×N (N:integer) of the operating frequency. <P>COPYRIGHT: (C)2013,JPO&INPIT |
