Abstract

A phased array analysis is presented where the coupling between antenna elements and the beam steering is computed in the time domain using a hybrid finite-difference time-domain (FDTD) and Kirchhoff transform method. The coupled currents are combined with the appropriate time delays to give the total element current, which is then used in conjunction with the voltage excitation to produce the driving point admittance as a function of frequency for a given beam direction.
