A Very-Near-Field Measurement Technique to Test Large Antennas in the Lab

摘要

When measuring the magnetic very-near-field of an antenna, it is fast and easy to obtain accurate estimates of the radiation pattern and power levels. By combining smaller snapshots of the very-near-field, a reasonably sized measurement array can also quickly measure very large antennas in the lab setting and get good estimates of the critical parameters. This solves the very expensive and time consuming problem of measuring arbitrarily large antennas in very large chambers or outdoor ranges.
