Design of a Parabolic Antenna for Telecommunication Satellite Payload in Ka-Band

In this paper, we will do a study which consists in simulation and configuration of a parabolic antenna embedded in the payload of a geostationary satellite in Ka-band; this antenna is responsible to ensure the communication between the satellite and receptor or earth station for multimedia service. First, we will study the parabolic antenna because it’s this type of antenna who interest us in our application, and we will study their different characteristics, after we will study the different types of parabolic antenna to choose the most appropriate model, in our study the parabolic antenna mounted in offset is the most appropriate. Finally, we will use specific software to simulate the antenna for arriving to determinate the different parameters that can give us the best performances practically.
