Abstract
A single element antenna with the ability to have pattern control by placing multiple feeds on opposite ends of the antenna element and controlling the amplitude and phase distribution of each of the feed ports.
Claims27
An antenna system comprising:
- a. a single antenna element comprising at least three feeds;
- b. an amplitude and phase control subsystem over the at least three feeds, whereby the amplitude and phase control is adapted to be used for each of the at least three feeds simultaneously to control azimuth and/or elevation radiation characteristics;
- and
- c. a combiner to combine the at least three feeds;
- wherein the amplitude and phase control subsystem is adapted to control the amplitude and phase on a sector-by-sector basis;
- wherein the sector-by-sector amplitude and phase control of each feed is adapted to be used respectively to progress or regress to a next or previous feed to rotate a pattern from a sector to a next or previous sector;
- wherein the amplitude and phase control subsystem is adapted to control the amplitude and phase within each sector for azimuth and/or elevation pattern control;
- and
- wherein “sector” is based on 360 degrees divided by a number of feeds in azimuth.
