Advanced Antenna Measurement Processing
Abstract
This research project is focused on the advancement of methods of post measurement processing of antenna pattern measurements to enhance their utility in assessment of antenna performance. Three specific techniques are treated; planar near-field extrapolation, planar near-field extended probe calibration, and the Super Iso-filter for separation of the radiation field into components originating from specified regions of the radiating structure. We show that planar near field measurement maybe extrapolated beyond the scan plane sampling region to provide wider angle far field results than otherwise obtainable. We also show that a calibration measurement in planar near field scanning can be used to remove artifacts arising from multipath effects on the measurement range. Finally, we demonstrate that the iterative processing embodied in the Super Iso-filter algorithm provides an effective and rigorously correct means of separating the radiation from two separate antennas using only data measured for both antennas radiating simultaneously. The three techniques treated here provide convenient and useful tools to the antenna engineer in designing and assessing the performance of antennas for practical use.
