This thesis presents the development of a hat-fed refector antenna with radome to be used as satellite earth station. The antenna with self supported feed is relatively compact, circular symmetric and with low cross polarization. To achieve optimum performance over the satellite Ku-band, covering 10.75-14.50 GHz, a genetic algorithm optimization scheme was implemented and the simulations were done with the electromagnetic solver QuickWave-V2D based on the FDTD method. Optimizations were done towards minimized reflection coefficient, maximized feed efficiency, and finally taking into account the stringent sidelobe requirements defined by the ETSI. Radomes for enclosing the satellite earth station have been analyzed and a low loss homogenous radome was manufactured and successfully measured with the hat-fed reflector antenna. The satellite earth station can after certification be operational.

Nyckelord: Antenna feeds, corrugated surfaces, reflector antennas, optimization, radomes, satellite earth stations.
