The NIST 18 term error analysis has been used for some time to estimate the uncertainty in the far-field antenna parameters determined from near-field measurements. Each of the error terms is… (More)

The results of theoretical calculations or measurements on antennas are generally given in terms of the vector components of the radiated electric field as a function of direction or position. Both… (More)

The properties of beamwidth, directivity, and polarization of wavelength-size scalar horns are analyzed and optimized theoretically and confirmed experimentally to determine the usefulness of such… (More)

A General Extrapolation Technique which corrects for the effects of ground reflections in absolute gain measurements is described. It utilizes the Extrapolation Method developed at NBS which, in its… (More)
