OPTIMUM APERTURE STUDY

Abstract

The objective of this analysis is to study the applicability of the Wiener-Spencer theorem to antennas. This theorem states that minimum standard deviation of the far-field power pattern occurs when the illumination function corresponds to the lowest mode of vibration of a membrane stretched across the aperture opening. The analysis concerns the first phase of this study in which various representative distributions and far-field power patterns for a linear and a square antenna are considered. A comparison of these distributions and the optimum distribution as determined by the Wiener-Spencer theorem is made. In addition, a survey is made of the known geometrical configurations in which Helmholtz's equation is separable. (Author)
