Abstract
An antenna for transferring electromagnetic energy includes: (a) a ground element in a ground plane; (b) a transceiver element in a transceiver plane that intersects the ground element at a first end in a joint having a first terminus and a second terminus; and (c) a feed structure that conveys the electromagnetic energy intermediate the transceiver and the host device. A first transceiver edge departs from the joint in a first path in a first direction. A second transceiver edge departs from the joint in a second path in the first direction. Each edge includes at least a first edge sector having a first radius and a second edge sector having a second radius. The radii define a separation between the edge sectors. The first and second edge terminate in a terminal structure at a second end that is spaced from the ground element to establish a gap.
