High gain pyramidal horn antenna for image data transmission in LEO satellites

In this paper a hybrid numerical technique is used for the design of high gain (22dB) pyramidal horn antenna radiating in free space. The electric field integral equation is employed on the outer surfaces of the pyramidal horn including the radiating aperture. Meanwhile, the magnetic field integral equation is used on the aperture to relate the aperture fields and those in the horn transition. The resultant hybrid field integral equation is solved numerically by the moment of methods. Far field radiation patterns, both computed and measured are presented in the paper. The comparison between the computed, measured and the simulated results shows greater accuracy and almost similar results showing successful design and implementation of X-band pyramidal horn antenna.
