Abstract:
A dual polarization antenna for receiving and transmitting high frequency signals in conjunction with a substantially horizontal ground plane, said antenna comprising:an electrically conductive first, second and third antenna element to receive horizontally and vertically polarized components and jointly resonate within three separate frequency hands, each said element being axially elongated and having a first end and a second end, and a mounting block comprised of a dielectric material adapted to be mounted to the ground plane, said mounting block electrically insulating said first, second, and third antenna elements from the vehicle ground plane and securing said antenna elements into a triangular arrangement such that said second ends are in electrical circuit path relation with one another and the first ends are spaced vertically upwardly and above said mounting block and circumferentially spaced at 120Â°, said first, second, and third antenna elements forming an imaginary cone, the center axis of the cone being generally perpendicular to the ground plane, the apex of the cone being formed by the second ends of the elements, and each of the antenna elements being disposed at an acute angle relative to the ground plane.
