NEW TECHNIQUES OF PATTERN SHAPING FOR LOW SILHOUETTE ANTENNAS

摘要

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, Experimental 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 obtained from a cosine to the even power modulation of the relative wave number.
