Measurement distance effects on $$\varvec{\phi}$$ -symmetric Taylor patterns with optimal transition integer $$\varvec{\overline{n}}$$ and with reduced inner sidelobes

Abstract

Abstract The following paper presents the findings of a study conducted on the distances at which the field generated by a $$\phi$$ -symmetric circular Taylor aperture distribution can be classified as far-field, and also the efficiency across various study parameters. The $$\overline{n}$$ transition integers that produce a monotonic distribution, which have been traditionally used and analyzed, are compared with those that yield a peaked distribution, and offer greater efficiency. Additionally, modified circular Taylor $$\overline{n}$$ distributions featuring synthesized patterns with one or two depressed inner sidelobes, which have not been previously explored, are also examined.
