This thesis has documented the work of implementing the new UiOground station which is situated at the University of Oslo. The stationis fully operational and it meets the needed requirements for a commu-nication link with satellites in low earth orbit.The antenna arrangement consists of four stacked Yagi-Uda antennasmounted on a frame with vertical booms made of fiberglass. The choiceof fiberglass over metal minimize degradation of the antenna radiationpattern and the antenna input impedance. The effects of stacking anten-nas have been simulated in FEKO simulation software which is based onMethod of Moments (MoM) integral formulation of Maxwell’s equations.To master all the details of the ground station requires a wide rangeof knowledge. The first chapters present some very useful backgroundtheory for gaining a better understanding of how the system works andhow it was tested. There has been a strong emphasis on providing thereader with a clear picture of the complete system and the theoreticalfoundation needed to understand this. Hopefully this will motivate futurestudents to take part in working with and improving the ground station.
