Dual polarised antenna
First Claim
1. A dual polarised antenna including two or more modules arranged along an antenna axis, each module including a radiating element, and four conductive walls which together form a frame around the radiating element, each wall including a distal edge and a pair of side edges, wherein the side edges of the walls meet, but do not touch, at respective comers of the frame.

Abstract
A dual polarised antenna including two or more modules arranged along an antenna axis. Each module includes a radiating element, and four conductive walls which together form a frame around the radiating element. Each wall includes a distal edge and a pair of side edges. The side edges of the walls meet, but do not touch, at respective comers of the frame. Conductive wall assemblies are arranged between a pair of radiating elements. Each wall assembly is substantially U-shaped as viewed in a cross-section taken along the antenna axis. Each radiating patch element has first and second opposite side edges which run substantially parallel with the antenna axis. An axial isolating element is arranged between each pair of radiating patch elements and includes an elongate conductive member arranged with its length substantially parallel with the antenna axis. A transverse isolating element is arranged between each pair of radiating patch elements and includes an elongate conductive member arranged with its length substantially transverse with the antenna axis. The axial and transverse isolating elements do not touch each other. Each side wall has a projection extending from an upper edge of the side wall. The projections are positioned opposite to a centre of a respective radiating element, and each projection lies in the plane of its respective side wall. The ground plane and conductive walls are formed from a single sheet of conductive material.
