Radio antenna arrangement with a patch antenna for mounting on or adjacent to the windshield of a vehicle
First Claim
1. A multiband radio antenna arrangement for use in two way radio communication for UHF and SHF frequencies in a motor vehicle comprising:
- at least two emitter antennas forming a first emitter antenna and at least one additional emitter antenna mounted on the outside of the motor vehicle adjacent to an upper edge of the vehicle'"'"'s windshield near its roof;
a base-plate secured adjacent to the roof of the vehicle, said emitter antennas being mounted on said base plate and projecting therefrom, said baseplate being electrically conductive and serving as the electrical ground plane for said emitter antennas;
at least one thin antenna line extending 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;
at least one patch antenna connected to said antenna line for receiving an additional radio communication service, said at least one patch antenna being mounted on said base plate between said first and said at least one additional emitter antennas;
at least one emitter connection point formed by said first emitter antenna and said at least one additional emitter antenna connecting to said baseplate and the antenna line; and
a patch antenna connection point formed by the patch antenna connecting to the base plate and the antenna line wherein said first emitter antenna and said at least one additional emitter antenna, said at least one antenna line, and said at least one patch antenna are linked to said base plate, to form a combination antenna for multiple band radio communicationsa network circuit coupled between said first and said at least one additional emitter antennas, and a group antenna connection point formed on said base plate and coupled to the antenna line for radio communications with a two way radio-telephone.

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.
