Abstract
With the advent of large space antennas, the prediction of the far-field radiation patterns of antennas from measurements made in their near field has been an area of considerable interest. A simplified probe-compensated cylindrical near-field measurements system has therefore been developed at the Communications Research Center. The theoretical basis of the system is a method by which both the field radiated by the antenna and that radiated by the measuring probe, when it is used as a transmitter, are transformed into cylindrical wave expansions. The Lorentz reciprocity theorem is then used to solve for the field radiated by the antenna from the probe output voltage.
