Abstract : Some of the sophisticated antenna systems which are now under development will have to be tested using near-field techniques, as conventional techniques cannot offer the accuracy required for an affordable cost. In this paper, attention is focused on the practical aspects of near-field antenna testing in spherical coordinates. The requirements for the antenna range and the antenna testing procedure are reviewed. The sources of measurement error are identified and several estimates of the error levels are made. Examples of near-field test results are compared with the measurements taken on a compact range.
