ABSTRACT:
A method and system for beam steering of a spatially fixed microwave antenna array. The phase of radiating elements and hence the beam position is established by the relative positions of a microwave disc or scan network having concentric microstrip paths thereon and a mechanically driven rotating directional coupler. The directional coupler is the single point feed for the antenna array.
