Abstract :
The design and development of a feed-horn antenna with flow sidelobe and low cross-polarization levels are reported. The E-walls of this antenna are fabricated with low-loss dielectric substrate, periodically loaded with thin conducting strips. The antenna simulates the radiation characteristics of metallic corrugated horns. This can be an ideal substitute for metallic corrugated horns, having added advantages like light weight and low production cost.<>
