Low profile bi-directional antenna
First Claim
1. A low profile bi-directional antenna adapted for mounting directly to a conductive surface, the antenna comprising:
- an insulating antenna tray having top and bottom surfaces;
a conductive ground plane having lateral side edges and mounted to one of the surfaces of the antenna tray;
first and second reflector elements mounted to a surface of the antenna tray laterally beyond said side edges of the ground plane and electrically connected thereto;
first and second radiating elements supported above the tray and the ground plane and spaced laterally beyond both said side edges and said first and second reflector elements respectively; and
an RF connector for coupling RF signals to and from the first and second radiating elements.

Abstract
A low profile bi-directional antenna is provided for mounting directly to a metal structure, or some other conductive or semi-conductive surface. The antenna includes an insulating antenna tray, a conductive ground plane mounted to a surface of the antenna tray, first and second radiating elements extending from the ground plane, and a radome covering the radiating elements and fastened to the insulating antenna tray. First and second reflector elements are mounted to the surface of the antenna tray on the lateral sides of the ground plane. The reflectors are electrically connected to the ground plane. The radiating elements are supported above and to the lateral sides of the ground plane and reflector elements by support members mounted at acute angles to the ground plane. An RF connector is provided for coupling RF signals to and from the first and second radiating elements.

16. A bi-directional antenna having a relatively low VSWR comprising;
-
an at least partially conductive mounting surface; an insulating antenna tray mounted to the at least partially conductive surface, the tray isolating the antenna from the at least partially conductive surface; a conductive ground plane mounted to the tray; a first reflector adjacent a first side of the ground plane, and a second reflector adjacent a second opposite side of the ground plane, the reflectors being electrically connected to the ground plane and defining outside edges opposite the ground plane; a first radiating element supported above and laterally offset from the first reflector beyond the outside edge thereof, and a second radiating element supported above and laterally offset from the second reflector beyond the outside edge thereof; and means for coupling an RF signal to the first and second radiating elements. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
