Design and Analysis of a Miniaturized Ku-Band Corrugated Conical Horn Antenna for Satellite Applications

A miniaturized Ku-band corrugated conical horn antenna is designed and optimized to achieve wide bandwidth for satellite applications. This antenna is designed using a perfect electric conductor (PEC) and is simulated using CST Studio Suite. The total length of the antenna is 59.42 mm. The presence of corrugations allow hybrid mode and ensure return loss below -85 dB, VSWR approximately 1, sidelobe level of -23.0 dB to -31.2 dB, and gain values of 12 dB to 28 dB over the Ku-band (12 GHz to 18 GHz). Besides, the directivity of 14.4 dBi is obtained at 16 GHz center frequency. The antenna impedance bandwidth (VSWR <; 1.5) is 1 GHz to 23 GHz which exhibits wideband characteristics that can be used for reflectors' feeding or satellite applications (e.g. direct broadcast satellite-DBS).
