Abstract
A fixed antenna includes multiple printed board panels, each containing an array of radiating elements where a subset of radiating elements receives a delayed signal from a feed layer. The number of panels is minimized by configuring each array to generate a shaped beam. The shaped beam is produced by non-uniformly spaced elements and non-uniform array element phase shifts.
