Abstract:

The ability to fully characterize a probe antenna using a near-field range is demonstrated subject to the conditions that two identical probes are available and that the E sub y field components are symmetric about the ky O axis. A completely general three antenna approach, requiring no such assumptions, appears feasible. Some questions with respect to uniqueness of solution of the three antenna approach remain. Experimental results indicate that at wide angles approx 77 deg, considerably below the apparent geometric limit, the planar near-field approach suffers a notable loss of accuracy. Improvements in both hardware and software techniques to increase the data handling ability of the near-field facility are described. Author
