Abstract
An antenna system and method use an electronically-scanned antenna array and a hybrid beam former architecture. The antenna system includes a matrix of antenna elements and a feeder network. The feeder network includes a first layer including phase shifters. Each of the phase shifters is for a respective antenna element of the antenna elements. The feeder network also includes a second layer and a third layer. Each of the first set of the first time delay units in the second layer is for a respective first subarray of the first subarrays of the antenna elements. Each of the second set of the second time delay units in the third layer is for a respective second subarray of the second subarrays of the first subarrays.
