Functioning satellite communication is a key part in everyday life and this thesis aims to contribute to the research area by exploring the characterisation of electrostatic discharges on antennas. Currently there is a gap in the research field when it comes to discharges on antennas and this thesis aims to try to fill that gap. Currently most research involves expensive electron beam and vacuum chamber testing. Simpler and more cost effective test methods are not as explored. This thesis explores current spacecraft charging and Electrostatic Discharge (ESD) standards, and how they can be used to analyze the charging and discharging characteristics of an antenna. The thesis involves how such a analysis is done and what limitations it may have. Two practical direct injection tests were also performed as to see how the antenna reacts to discharges of different energies and voltages. Finally a proposal of a test setup for an electron beam test was done. The main findings of the thesis is that there may be a risk of sustaining damage from the level of discharges measured despite the antenna fulfilling current standards and recommendations. Another take-away is that more research is required to establish if simpler analytic or practical tests are applicable for characterising discharges on the antenna.
