Abstract
This thesis has documented the work of implementing the new UiO
ground station which is situated at the University of Oslo. The station
is 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 antennas
mounted on a frame with vertical booms made of fiberglass. The choice
of fiberglass over metal minimize degradation of the antenna radiation
pattern and the antenna input impedance. The effects of stacking anten-
nas have been simulated in FEKO simulation software which is based on
Method of Moments (MoM) integral formulation of Maxwell’s equations.
To master all the details of the ground station requires a wide range
of knowledge. The first chapters present some very useful background
theory for gaining a better understanding of how the system works and
how it was tested. There has been a strong emphasis on providing the
reader with a clear picture of the complete system and the theoretical
foundation needed to understand this. Hopefully this will motivate future
students to take part in working with and improving the ground station.
