The Mathematical Absorber Reflection Suppression (MARS) technique is a method to reduce scattering errors in near-field and far-field antenna measurement systems. Previous tests by the authors had indicated that NSI’s MARS technique was not as effective for directive antennas. A recent development of a scattering reduction technique for cylindrical near-field measurements has demonstrated that it can also work well for directive antennas. These measurements showed that the AUT should be offset from the origin by a distance at least equal to the largest dimension of the AUT rather than only 1-3 wavelengths which had been used for smaller antennas in the earlier MARS measurements. Spherical near-field measurements have recently been concluded which confirm that with the larger offsets, the MARS technique can be applied to directive antennas with excellent results...
