VARIABLE SLOT ANTENNA AND METHOD FOR DRIVING SAME

摘要

A variable slot antenna is provided with grounding conductors (101a, 101b) whose both ends are divided by a slot area (109) of open ends (111a, 111b); a power feed line (115) employing a loop shape for a power feeding area (113) to a slot area (109); a first selective conducting path (119) for connecting the grounding conductors (101a, 101b) on the side facing the open end (111a) from a power feeding area (113); and a second selective conducting path (121) for connecting the grounding conductors on the side facing the open end (111b) from the power feeding area (113). Conduction status and open status of the first selective conducting path (119) and the second selective conducting path (121) are changed by driving status.
