AbstractA dual polarization antenna for receiving and transmitting high frequency signals in conjunction with a substantially horizontal conducting vehicle panel defining a ground plane comprises three electrically conductive radiative elements, each radiative element being generally linear and extending between a proximal end and a distal end, and an electrically conducting mount (insulated from the vehicle panel) for securing the proximal ends together at a common point and in electrical circuit relation with one another for connection to a transceiver in the vehicle. The radiative elements extend vertically upwardly and outwardly from the common point whereby to form an imaginary cone with the proximal ends forming the apex of the cone. The radiative elements are of different lengths and disposed at an angle relative to the ground plane to provide horizontal and vertical polarization in a first, second and third frequency band.
