NEW TECHNIQUES OF PATTERN SHAPING FOR LOW SILHOUETTE ANTENNAS

Abstract

The infinite modulated reactance sheet is studied with the phase and amplitude contours of the near field presented. It is shown that the infinite reactance sheet is an excellent description of the modulated Yagi. Experiment al radiation patterns of low-sidelobe endfire arrays are given together with radiation patterns of Yagi arrays giving cosecant type radiations, flat-top flared beams, and beams at an arbitrary angle. The beams at an arbitrary angle are ob tained from a cosine to the even power modula tion of the relative wave number.
