Placement Analysis of Isoflux Pattern Corrugated Horn Antenna on a Earth Observation Satellite Platform for LEO Altitude

In this study, a concentric corrugated horn antenna on Electro-Optical earth observation satellites and Synthetic Aperture Radar (SAR) satellites operating in Low Earth Orbit (LEO) is designed and a placement analysis of this design is performed on a symbolic satellite platform in X-band. The analyzes were carried out in the free-space environment of the antenna in CST in time domain. Antenna placement analyzes on the platform were performed in Asymptotic Solver in CST Studio Suite and in Shooting Bouncing Rays-SBR in FEKO. Finally, the obtained results were evaluated and the two analysis programs were compared.
