Arbitrary Footprints from Arrays with Concentric Ring Geometry and Low Dynamic Range Ratio

A common method of antenna array synthesis uses least-squares approximation to fit the radiation pattern of the array to a set of samples of an ideal desired pattern F id . However, it has long been known that discontinuities in F id prevent close approximation, and that sampling a target pattern F...

Description
Summary:A common method of antenna array synthesis uses least-squares approximation to fit the radiation pattern of the array to a set of samples of an ideal desired pattern F id . However, it has long been known that discontinuities in F id prevent close approximation, and that sampling a target pattern F tar that approximates F id can afford better results. Here we show, for the case of circular planar arrays, that an appropriate target pattern can be obtained by modification of a Taylor pattern for a circular aperture.
