A Dielectric-Loaded Horn with Periodic Strip Structure
MetadataShow full item record
A dielelectric-loaded horn with transverse strips is analysed theoretically. The method is based on a planar periodic strip structure and is used for a circular cylindrical and uniform waveguide model of the feed. The propagation constant and the total field can be determined by approximate solution for the "dominant" Floquet mode with n = 0. Radiation pattern of the feed with small flare angle is computed as a superposition of the field components radiated from center of the aperture and from its region filled with dielectric.
