Guided Modes in Solid Dielectric Horn Antenna : Propagation Characteristics of guided modes in solid dielectric horn antenna

Here, an analytical theory has been developed for finding out the modal characteristics of a solid dielectric pyramidal horn. The dispersion characteristics have been solved numerically by varying various parameters, such as, axial length, flare angle and relative dielectric constant of the horn to investigate the modal characteristics which is crucial to include or avoid higher order modes in dielectric horn antenna design.
