Abstract
A communication device provides an elongate antenna element having a first and a second end separated by an aperture. A transceiver is electrically grounded to a ground plane and communicatively coupled via an antenna feed to the elongate antenna element. A first conductor is electrically attached to a first edge of the ground plane. An antenna switching controller selectively actuates the aperture switch to be in one of the open and closed positions based on whether the communication device is positioned on a body. The open position electrically isolates (a) the first end of the elongate antenna element; (b) the second end of the elongate antenna element; and (c) the first conductor. The closed position electrically couples: (a) the first end of the elongate antenna element; (b) the second end of the elongate antenna element; and (c) the first conductor.
