Abstract :
In this paper, we present a technique to calculate near and far-field phase center of axially-symmetric feeds using finite difference time domain method of bodies of revolution. To illustrate the application of the proposed approach, several feeds are analyzed. The numerical results show good agreement with those obtained by using analytical expressions
