Abstract

In this paper, we describe the synthesis of circular-Taylor-like patterns for antennas composed of concentric rings of uniformly excited elements. Optimization of the ring radii achieves close approximation to the envelope of the desired pattern within a given cone about the main beam. An alternative approach, using annular subarrays, speeds computations by limiting the number of between-ring spacings. Examples illustrate the potential of these methods.
