Preliminary Study of a Lens Antenna for a Solar Power Satellite

Aiming to develop a solar power satellite system, this study deals with the power transfer subsystem, specifically the microwave radiation and focusing. In order to reduce the spillover losses the radiation will be analyzed through the quasioptics framework. For that purpose, a 27 GHz gaussian beam generated by a rectangular horn antenna was focused by a dielectric lens. The design procedure for the components is presented here as well as the simulation results of just the horn antenna and the horn with the lens. A comparison of both results will be provided, with a discussion on the use of the dielectric lens for focusing the radiation.
