ABSTRACT:
A multiband radio antenna arrangement for use in two way radio communication for (UHF) and (SHF) frequencies. The antenna arrangement contains at least one emitter antenna mounted on the outside of the motor vehicle adjacent to an upper edge of the vehicle's windshield near its roof. Supporting the emitter antenna is a base plate secured adjacent to the roof of the vehicle, the baseplate being electrically conductive and serving as the electrical ground plane for the emitter antenna. A thin antenna line feeds into the antenna and extends from a connection point on the baseplate to the upper edge of the windshield where it is bent and then extended on the inside surface of the windshield through an adhesive bead of the window and into the interior of the vehicle. In addition, connected to the baseplate is a patch antenna connected to the antenna line, the patch antenna for receiving an additional radio communication service. The emitter antenna connects to the antenna line on the baseplate at an emitter connection point. The patch antenna connects to the antenna line on the baseplate at a patch antenna connection point. The combination of the emitter antenna, the antenna line, and a patch antenna are linked to a base plate, to form a combination antenna for multiple band radio communications.
