A novel multimode pyramidal horn with symmetric dielectric loading on the horn walls is presented. The horn possesses the desirable features of high aperture efficiency (on-axis gain), low sidelobe levels, and low cross polar radiation suitable for applications in satellite communication. In the development of this efficient pyramidal horn, the technique of multimode generation of high order TE/TM/sub 12/ modes by a step discontinuity and a change ill the horn flare angle for equalizing E- and… CONTINUE READING
