Immittance properties of large finite dielectric covered phased arrays
Abstract
A method is presented for analyzing large finite phased arrays of antennas. The foundation for the procedure lies in a recently developed method for analyzing periodic surfaces. That method begins with the vector potential for a two dimensional array of Hertzian dipoles expressed as a double infinite sum of spherical waves. The Poisson sum formula with a Fourier transform and inverse transform then yields a double infinite sum of plane, inhomogeneous waves. Simulating a finite array is accomplished by modulating the input forcing function (current in the dipole case, voltage in the aperture cases) in such a way as to form an infinite number of finite arrays, separated by areas with zero forcing function. The response function (voltage for dipoles, current for apertures) is calculated with the immittance being the ratio of the forcing and response functions.
