Fast Spherical Near-Field Antenna Measurement Methods

In this thesis, different methods for accelerating spherical near-field antenna measurements are investigated and evaluated. The work focuses on time-efficient sampling grids. Measurement time reduction up to 50% can be achieved without significant reduction of the accuracy. In general, the spherical mode spectrum can be determined with the developed methods from measured data on any closed measurement surface. This increases the degrees of freedom in antenna measurement applications.
