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) for feeding the slot area (109) with power; 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). In a first driving status, electricity is carried in the first selective conducting path (119), the second selective conductive path (121) is opened, and a main beam is applied from the area (113) in a direction (123a) facing the second selective conductive path (121). In other driving status, control of the selective conducting path is switched and the main beam direction is switched to a side (123b).
