초록
Dual band horn with TE11 coaxial waveguide mode was designed for the feed of the focused reflector antenna. The coaxial waveguide was adopted to simultaneously operate higher frequency and lower frequency, and to reduce the size. This paper showed the improved return loss and symmetrical pattern by matching element and dual mode. The performance of the optimized horn structure was verified thru the measurement.
