Characterisation of X/S Large, High Gain, Ground Station Antenna in Outdoor Test Range

Abstract

It is important and tedious job to characterize large, ground station antenna within specified confidence limit. This requires an extensive measurement program to characterize large antennas (10 mtrs and above). In this paper various aspects of testing and optimizing the antenna performance in outdoor test range (> 5 kms) are discussed. This can be used as a reference guide by other antenna engineers for the optimisation of antenna performance in outdoor test ranges for high gain antennas.
