A Study of the Application of Statistical Aspects of an Electromagnetic Field to the Design of Antennas.
Abstract
The performance of linearly-polarized rectangular aperture antennas receiving independent partially coherent signal and noise fields is investigated. An expression for the signal to noise power gain (referred to an isotropic point detector) for a linearly polarized antenna is developed. The parameters in the expression are the mutual coherence functions of the signal and noise fields, the dimensions of the aperture and the amplitude weighting function of the aperture. It is shown that the signal to noise power gain of an antenna is not a linear function of aperture area when the signal field is partially coherent. For certain signal/noise fields it is shown that the gain of an antenna approaches a limiting value as the area of the antenna's aperture is increased. This can not be predicted through the classical antenna design procedures. (Author)
