A Strip-Loaded Feed-Horn Antenna

Design and development of a new feed -horn antenna with low sidelobe levels is reported . The E-walls of this antenna are fabricated with low -loss dielectric substrate , periodicallyloaded with thin conducting strips . The antenna is found to be simulating the radiation characteristics of metallic Corrugated horns . This can be an ideal substitute for metallic Corrugated horns with added advantages like light -weight and low production cost
