AN INVESTIGATION OF THE POINT SOURCE CONCEPT FOR MICROWAVE HORN AND POLYROD ANTENNAS,

Abstract

It would be desirable in many applications to consider a microwave antenna as a point source. This thesis examines to what extent actual antennas may be treated as point sources. The point source concept as applied to five antennas was investigated by measurement of the change in phase as a receiving antenna was rotated about various axes. Measurements were made on three pyramidal horn antennas, a ceramic antenna, and a polystyrene antenna. It was found that only the small horn antenna could be treated as a point source to a good approximation for the angles through which phase measurements were made and that the other antennas have a different center of phase location for each plane of rotation.
