ABSTRACT:
A single planar antenna for use in two frequency bands includes radiating portions for the two bands joined by a connecting portion and spaced from a ground plane. Each radiating portion is formed as a planar inverted F-antenna. A grounding pin interconnects the connecting portion and the ground plane and a single feed pin connects the connecting portion to the input/output port of transceiver circuitry.
