An antenna system and method for constructing said system from a plurality of antenna elements. An antenna system radiation pattern function is specified. The antenna elements are determined by measurement, simulation or calculation and parameterized according to interelement spacing within the array. The parameterized array elements are collected to form a set that is identified with a frame. A dual frame to the element frame is determined and antenna element weights are computed based on the dual frame and the specified system radiation pattern function. The antenna system is then constructed in accordance with the antenna element weights. The antenna element frame enables high-quality low SLL beams, irregular interelement spacing, arbitrary geometries of linear and planar arrays, time and space arrays, multi-band arrays and inclusion of element phase variations due to differences in element feeds in the constructed antenna system.
