Abstract
An antenna assembly has a plurality of conductive elements to enable use in multiple frequency bands assigned for a mobile wireless communications. The antenna assembly has a six-sided support frame non-electrically conductive material which provides external surfaces on which specific conductive patterns are formed with the patterns on different surface being selectively connected together. The support frame is mounted on one major surface of a dielectric substrate that has an opposite major surface with a conductive layer that serves as ground plane. A portion of the opposite major surface, on which the conductive layer is not applied, forms one surface of the support frame.
