Efficient filtering of cable interaction in small antenna measurements

Abstract

This communication presents a novel technique to deal with undesired interaction of the AUT with cables and other nearby disturbances. Its key features are: i) it allows removal of the effect of disturbances on antenna pattern, ii) it requires only approximate geometrical knowledge of the AUT and disturbing objects and iii) it is a fast data post-processing step that puts no special requirements on the measurement procedure, which may be performed in the usual way (no baluns, chokes, etc.).
