Patent abstract
Feed point (101) performs unbalanced feeding to an antenna element (102). A parasitic element (104) is provided near the antenna element (102) and a ground plane (103), approximately parallel to the width direction of the ground plane (103). Moreover, the parasitic element (104) is configured in a length to operate as a director when provided on the side of the body with respect to the ground plane (103) during talk time and in a length to operate as a reflector when provided on the opposite side from the body with respect to the ground plane (103). By this means, it is possible to improve gain and reduce the specific absorption rate (SAR) during talk time.
