Electrically long waveguide-slot antennas with optimal radiation and directivity characteristics

Victor A. Katrich, V. A. Lyashchenko, S. L. Berdnik


The paper is devoted to theoretical and experimental investigation of radiation pattern, directivity and gain factors, and frequency responses of electrically long longitudinal slots cut in a broad wall of finite thickness in a rectangular waveguide. The authors have analyzed the dependence of slot antennas’ directivity characteristics on physical dimensions of slot radiators, their location in the waveguide wall, and physical dimensions of the waveguide itself. The calculations are performed in the single- and multimode conditions.
