Abstract :
Radiation pattern measurements of antennas mounted on vehicles present difficulties in centering the AUT with respect to the axes of rotation of the measurement system. Gain corrections dependent on the measurement system geometry have been implemented to correct the variation in the measurements introduced by the AUT offset. An outdoor antenna range is described, measurement repeatability is established, expressions for the corrections are given, and examples of corrected measurement results are presented.
