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 continuously adjusts phase shifters of a feed distribution network to radiating elements to continuously vary antenna beam tilt. A controller enables the beam tilt of a number of antenna at a site to be remotely varied.

Abstract: A cellular base station telecommunication system includes a plurality of base station antenna sites, each site having one or more groups of base station antennas. A central controller is configured to control an electrical or mechanical parameter in one or more of the antennas in the groups of antennas.

Abstract: A method of mounting an antenna to a support, the method including the steps of: a) mounting first and second clamps to the support; b) tightening the first clamp around the support; c) mounting the antenna to the first clamp; d) after step c), moving the second clamp along the support away from the first clamp into engagement with the antenna; and e) tightening the second clamp around the support. The antenna is suspended from the first clamp by gripping the antenna below its upper end; lifting the upper end of the antenna over the first clamp mounted at an elevated position; and lowering the upper end of the antenna onto the first clamp so that interlocking male and female parts of the clamp and the antenna couple together. The clamp has three or more clamping members and three or more tighteners which can each be adjusted to tighten together a respective pair of adjacent clamping members so as to tighten the clamp around the support. The clamp can be provided in kit form.

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.
