Research paper thumbnail of Modeling the illumination function of a cassegrain reflector for a corrugated horn feed and calculation of the far field pattern

Abstract— A model of the illumination function of cassegrain reflector for a corrugated horn feed... more Abstract— A model of the illumination function of cassegrain reflector for a corrugated horn feed is presented here. A conical corrugated feed horn designed for a Ku band cassegrain reflector is simulated. The simulation data is compared to the illumination function. Comparison ...

Research paper thumbnail of Analysis of a conical corrugated horn operating in the K-band with low cross-polarization and high aperture efficiency, and observing its radiation patterns

Abstract In this paper, a simulation based design and analysis of a conical corrugated horn is pe... more Abstract In this paper, a simulation based design and analysis of a conical corrugated horn is performed. The design concentrated on reduction of cross-polarization. Optimizing the parameters for operation in a frequency band rather than a single frequency required ...

Research paper thumbnail of Design of an X band aperture matched horn antenna by optimization of back-lobe and cross-polarization level

In this paper, an aperture matched horn antenna is designed for operation in the microwave X band... more In this paper, an aperture matched horn antenna is designed for operation in the microwave X band region. A conical horn is designed first, and the effect of additional aperture matching structure is studied to find the optimum dimension of the structure. The study is performed through computer simulation by Finite Element Method. Finally, the performance of the designed horn antenna for band operation is simulated. The obtained structure through simulation provides optimum performance in terms of backlobe level and cross polarization level.
