Abstract

The expression for the inner mutual admittance of inclined slots in a narrow wall of a rectangular waveguide with broad wall penetration was obtained. The expression for the radiation pattern was obtained. The radiation patterns and magnitude distribution of antenna with closely spaced slots are presented. It is shown the possibility to create magnitude distributions in aperture by means of variation of tilt and dimensions of cut in the broad walls of a waveguide for each slot.
