Abstract
The specification discloses a dual-band antenna for receiving signals in both the PCS (digital phone) and AMPS (analog phone) frequency ranges. The antenna includes a ground plane, and upper and lower antenna elements spaced both from one another and from the ground plane. The two elements and the ground plane are parallel to one another. A plurality of shorting posts symmetrically arranged about the lower element connect the lower element to the grounding plane. A probe or lead interconnects the centers of the upper and lower antenna elements. The lower element is tuned to a first frequency range, and the upper and lower elements together are tuned to a second frequency range.
