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.

Abstract: A combination satellite and terrestrial antenna system for a single-source application. A first embodiment includes a cross dipole for receiving the circularly polarized satellite signals, and a plurality of monopoles for receiving linearly polarized terrestrial signals. The mono-poles are arranged symmetrically about the cross dipole. Alternative embodiments include a helix antenna for receiving the satellite signals, and one or more linear antennas arranged symmetrically with respect to the helix for the terrestrial signals.

Abstract: A vehicle window/antenna system with enhanced heating and AM/FM reception. The system includes a window and a heating/antenna grid supported thereon. The grid is separated into upper and lower portions, and functions as an FM antenna. A flat AM antenna is supported on the window between the upper and lower grid portions. The positioning of the AM antenna within the heating grid enables ice and snow to be cleared from the AM antenna. Antenna leads extend from both the upper and lower grid portions as well as the AM antenna. The two FM leads are connected to a Balun transformer to balance the FM signals.
