The subject of this thesis was commissioned by Verkotan, where the objective was to learn a theory behind plane wave conversion and develop an in-house software solution for Rohde & Schwarz’s PWC200. The work on this subject started by researching an antenna measurement theory and examining different hardware solutions where the measurement could be automated as far as possible.
Python was chosen for a programming language for its flexibility, and suitability for a data analysis. The development of the system can be divided into two categories, calibration and measurement. Calibration is essential for later measurements, which is why it was first developed. A calibration automation program was made, it consists of PWC communications, data parsing and calibrations. The measurement program used a set of different measurement instruments to communicate different phases of the measurement.
The validation measurement between the manufacturer and the developed measurement system showed that antenna patterns are nearly identical, which proved that the system works as intended. The development took a lot of time, but it produced a working measurement system, which can be later further developed.
