    Abstract: A radiating element for dual polarised operation in a linear antenna array is disclosed. The radiating element is a dual polarised radiating patch element consisting of a ground plane, a lower patch, an upper patch and parasitic elements. The lower patch and upper patch are stacked above the ground plane in a spaced apart relationship. The parasitic elements lie in the same plane as the lateral edges of the lower patch. Supports are used to hold the patches and the parasitic elements in a spaced apart relationship. The parasitic elements are fed from a central area of the lower patch by microstrips. The ground plane has apertures which are of a dumbbell shape to achieve the same effective length as long apertures. Orthogonally disposed strip type driven elements span across the central portions of the apertures and the length of these strips is selected to achieve the desired matchings. The feed to the driven elements will typically form part of a feed network etched onto a PCB mounted adjacent to the ground plane with conducting elements facing away from the ground plane. One requirement of this device is that the return loss at each port must satisfy a certain minimum level over a given frequency band. This is satisfied by employing an aperture coupled stacked patched configuration. Another requirement is that isolation between the two ports has to satisfy a certain minimum allowed level which is achieved by obtaining almost perfuect symmetry in one plane. In order to narrow the beam width for the vertically polarised radiation parasitic elements are provided which are feed from a region located near the middle of the lower patch via microstrips.

    Abstract: A method of forming an antenna by providing a first panel including a first conductive sheet secured to a sheet of dielectric material and forming one or more radiating elements and/or a feed network in the conductive sheet by forming grooves in the conductive sheet. The first panel may be a construction grade building panel or a similar suitable panel. The method enables panel antennas to be manufactured using inexpensive materials using inexpensive manufacturing processes.

    Abstract: An antenna control system enabling the remote variation of antenna beam tilt. A drive means (5, 30) continuously adjusts phase shifters (1, 2, 3; 36, 39, 40) feed distribution network to radiating elements to continuously vary antenna beam tilt. A controller (80) enables the beam tilt of a number of antenna at a site to be remotely varied.
