Abstract :
A novel design of dual-polarized broadband 6~18GHz horn antenna with low SWR (<;2), high gain (13dB~19.5dB) and high isolation (>25dB) is presented. Moreover, the designed antenna exhibits excellent far-field radiation characteristics in the entire operation bandwidth without beam splitting. Applying commercial software Ansoft HFSS, sensitivity analysis is taken with respect to the best antenna performance and manufacturing tolerance. Based on the results, we finally fabricated a sample, the measured results showed good performance.
