The paper presents the parametric study of asymmetric sine squared profiled corrugated horn. Ring-loaded-slot-mode converter sections are used to convert dominant mode, TE11 in to hybrid, HE11 mode to achieve wider bandwidth. The design parameters of sharp edges and smooth edges ring-loaded-slot-mode converter are described. The radiating and transmission characteristics of asymmetric sine squared profiled corrugated horn are optimized and presented for both type of mode converters. The bandwidth of 2.22∶1 has been achieved for asymmetrical sine squared profiled corrugated horn with smooth edges ring-loaded-slot-mode converter.
