Abstract:

The applicbility of the Wiener-Spencer theorem to antennas is studied. This theorem states that minimum standard devition of the far field power pattern occurs when the illumination function corresponds to the lowet mode of vibration of a membane stretched across the aperture opening. This Quarterly Report presents the analytical solutions of optimm illumination distribution for two selected antenna apeture configurations, namely, polygonl and elliptical. The respective expressions for far-field power diffraction pattern, the zeroth and second moments, are also presented. Author
