Abstract
An antenna for a phased array comprises a plurality of rectangular sub-arrays of individual array elements. The rectangular sub-arrays in the plurality are tiled to reduce periodicity of phase centers of the sub-arrays. The antenna utilizes a phase shifter for each sub-array as opposed to using a phase shifter with each individual array element.
