发明名称 ANTENNA APPARATUS
摘要 PROBLEM TO BE SOLVED: To solve the problem of a current which is paired with a current flowing through a radiation board 12 being not induced in a ground conductor 11, and power being radiated not only from the radiation board 12 but also from the ground conductor 11, so that one portion of power that is radiated from the ground conductor 11 is absorbed by a human body and an antenna gain decreases, in a call state where the ground conductor 11 approaches the head, hands or the like of a human body, and at the same time, a built-in antenna is completely incorporated into the enclosure at a terminal, so that the section can be retained easily by hands and further a gain decreases in this case. SOLUTION: A linear conductor 4 is installed, so that at least one portion is exposed to the outside of a radio terminal.
