<p>PROBLEM TO BE SOLVED: To prevent antenna characteristics of a ground wave mobile terminal from being fluctuated and also maintain excellent antenna sensitivity regardless the presence/absence of an adapter type satellite communication terminal in a ground radio communication mode by covering at least either surface of 1st or 2nd wiring conductor with magnetic material. SOLUTION: A magnetic sheet 13 is laminated to either flexible cable 4 of a ground wave mobile terminal or an adapter type satellite communication terminal. When a ground current flowing into a circuit board 2 from the vicinity of the antenna feeding point of the ground wave mobile terminal is made to start to flow to the adapter type satellite communication terminal through a contact connector 5 by sticking the sheet 13 to the cable 4, it is reflected or absorbed by the sheet 13 in a frequency band used by an antenna. Then, the antenna characteristics of the ground wave mobile terminal are no longer affected by the change of the ground state of the adapter type satellite communication terminal.</p> |
