  • Antenna control system
    Publication number: 20020135530
    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.

  • Antenna control system
    Publication number: 20020113750
    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) of a 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.

  • Dual polarised patch-radiating element
    Patent number: 6236367
    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.
