Abstract
An antenna apparatus includes a ground plane, a first dielectric layer disposed on the ground plane, a conductive line having a feeding point and an open end or a short end and disposed on the first dielectric layer, a second dielectric layer disposed on the first dielectric layer, a plurality of first conductive elements disposed on the second dielectric layer so that the first conductive elements intersect with the conductive line at a plurality of first positions corresponding to nodes of a standing wave of current flowing through the conductive line, and one or more second conductive elements disposed on the second dielectric layer so that the one or more second conductive elements intersect with the conductive line at second positions corresponding to antinodes of the standing wave between the second end and the first position closest to the second end among the the first positions.
