Zusammenfassung / Abstract

The evaluation of the performance of an antenna measurement chamber becomes an ever more important part of both the validation and maintenance therein. Key antenna performance parameters such as gain, directivity, radiation pattern and polarization depend highly on the planarity of the field distribution of the quiet zone. In order to meet the demands of current and future antenna measurements, modern measurement ranges have to meet strict requirements on the field distribution inside the quiet zone. In order to verify that the measurement range meets these strict requirements, the measurement setup and algorithms used for the evaluation of the quiet zone performance need to be improved accordingly.

Quiet zone spherical near-field scanning provides a solid basis for the performance evaluation of a far-field antenna measurement chamber. This work will develop and show the application of several algorithms using quiet zone spherical near-field scanning which can be applied to asses the performance of an antenna measurement chamber and the associated measurement uncertainty applicable to antenna measurements within.
