Abstract
An antenna is provided for a wireless communication device such as a handheld radio or cellular telephone. The antenna may be either embedded internally in the transceiver or may be mounted externally thereof. The antenna comprises a pair of 1/4 wave radiating elements which are coupled out of phase to create an end fire bi-directional pattern for the antenna. The radiating elements are attached to a micro-strip transmission phasing device which is comprised of a center conductor, a ground plane and a substrate material. The micro-strip transmission phasing device supplies a zero degree to one hundred eighty degree phase shift from one radiating element to the other radiating element.
