Abstract
An antenna system for wireless networks having a dual stagger antenna array architecture is disclosed. The antenna array contains a number of driven radiator elements that are spatially arranged in two vertically aligned groups each having pivoting actuators so as to provide a controlled variation of the antenna array's azimuth radiation pattern.
Claims19
An antenna for a wireless network, comprising:
- a reflector;
- a first plurality of radiators pivotally coupled along a first common axis and movable relative to the reflector;
- and
- a second plurality of radiators pivotally coupled along a second common axis and movable relative to the reflector;
- wherein the first plurality of radiators and the second plurality of radiators are staggered relative to each other and are configurable at different angles relative to the reflector to provide variable signal beamwidth;
- and
- wherein the first and second plurality of radiators respectively comprise first and second radiator elements extending from the plane of the reflector and wherein the first and second plurality of radiators are configurable from a first setting with the first and second radiator elements oriented parallel to each other to a second setting with the elements nonparallel to each other.
A method of adjusting signal beamwidth in a wireless antenna having a first plurality of radiators pivotally coupled along a first common axis relative to a reflector and a second plurality of radiators pivotally coupled along a second common axis relative to a reflector, comprising:
- adjusting the first plurality of radiators to a first angle relative to the reflector and the second plurality of radiators to a second angle relative to the reflector to provide a first signal beamwidth;
- and
- adjusting the first plurality of radiators to a third angle relative to the reflector and the second plurality of radiators to a fourth angle relative to the reflector to provide a second signal beamwidth,
- wherein the first and second angles are equal and the third and fourth angles are different.
