ABSTRACT:
A composite antenna comprising a first and second antenna suitable for transceiving independent signals in the cellular communication and GPS bands. The first antenna has upper and lower electrically conductive discs of substantially the same size aligned substantially in parallel, a first means for application of a first electrical signal between and at substantially geometric centers of the discs, and a plurality of electrically conductive shunts. The second (GPS) antenna is attached atop the upper electrically conductive disc and has a second means for application of a second electrical signal to the GPS antenna which traverses the electrically conductive discs whereby there is no significant degradation in performance of either the first cellular antenna or the second GPS antenna. The shunts are electrically connected to the first electrically conductive disc and the second electrically conductive disc, whereby the first and second electrically conductive discs are spaced from each other by a volume of free space or a volume occupied by a dielectric material. Also described is an antenna for cellular communications alone, with first and second electrically conductive discs spaced from each other by a volume of free space or a volume occupied by a dielectric material, without the second GPS antenna.
