Design and Simulation of Horn Antenna in x-Ku Band for Satellite Communications

Horn antennas are widely used antennas in satellite applications mainly because of their physical robustness and capability to operate at high frequencies. In this work an attempt has been made to design a pyramidal horn antenna along with associated waveguide to operate in X-Ku band (9.5 to 14.5 GHz). The design was simulated using High Frequency Structure Simulator (HFSS). HFSS is a widely used tool when it comes to design and simulation of any antenna system. Initially by using design formulas, the dimensions of the horn structure and waveguides are found and then they are fed into HFSS to simulate in the mentioned frequency band. The performance parameters like return loss, radiation pattern, directivity and cross-pol isolation were considered for the simulation. Finally, with this design we will be able to reduce the operation costs in launching any communication satellites for broadcasts.
