In recent years, the compact range has become a popular measurement tool in the evaluation of microwave antennas. This trend leads to the use of larger reflectors over larger frequency bands. Those reflectors can be built to the required accuracies, but they have to be assembled from many panels which introduce interpanel gaps. The electromagnetic scattering produced by the gaps affects the uniformity of the field in the quiet zone of the compact range. An analytical approach coupled with experimental determination of a key parameter has been developed to quantify the effect of the scattering from the interpanel gaps in a compact range. The results show the significance of this effect on the copol and x-pol distribution in the quiet zone area.
