Abstract
An azimuth beamwidth variable antenna array for a wireless network system is disclosed. A multi-column antenna array architecture is employed having a mechanical azimuth beamwidth adjustment capability. The array comprises a plurality of driven radiating elements that are spatially arranged having movable Aperture Coupling Patch (ACP) radiating—receiving elements so as to provide a controlled variation of the antenna array's azimuth radiation pattern.
Claims25
An antenna for a wireless network, comprising:
- first, second and third reflectors each having one or more radiators coupled thereto, the second reflector configured adjacent to and between the first and third reflectors;
- wherein the second reflector is generally planar and movable relative to the first and third reflectors in a direction generally perpendicular to the planar surface of the second reflector.
A mechanically variable beam width antenna, comprising:
- a reflector structure having plural reflector panels with respective generally planar panel surfaces oriented in different directions, the plural reflector panels including a center panel and first and second outer panels;
- a first plurality of radiators coupled to the first outer panel and configured in a first column;
- a second plurality of radiators coupled to the second outer panel and configured in a second column;
- a third plurality of radiators coupled to the center panel and configured in a third column;
- at least one actuator coupled to the center panel;
- wherein the center reflector panel is movable relative to the other panels from a first configuration wherein adjacent edge portions of the panel surfaces are contiguous to a second configuration where the center panel surface is spaced above or below the adjacent edge portions of the outer panels.
A method of adjusting signal beam width in a wireless antenna having a plurality of radiators configured on at least three separate reflector panels including two outer panels and a center panel, wherein at least the center panel is movable in a direction generally perpendicular to a plane of the reflector panel, the method comprising:
- providing the reflector panels in a first configuration where adjacent panel edge portions are aligned to provide a first signal beam width;
- and
- moving the center panel in a direction generally perpendicular to the surface of the panel to a second configuration wherein the center panel is spaced apart in a direction generally perpendicular to the panel surface from the adjacent panel edge portions of the outer panels to provide a second signal beam width.
