We performed electrical field simulations on a newly developed array feed dielectric lens antenna using the powerful simulation abilities of FEKO suite 5.3 for dielectric objects. The array feed comprises patch antennas printed on a dielectric substrate. The diameter of the dielectric lens antenna is approximately 13 wavelengths. In the simulation, the Multilevel Fast Multipole Method is employed. The simulation requires the total memory of 5.1 GBytes and approximately 20 hours to execute. The simulation results verify the effects of the array feed. The results also clarify the electrical field distributions on the antenna aperture plane and show the existence of small ripples in the electrical field distributions. We show that reflected waves at the lens surfaces cause these ripples. Most importantly, the results verify excellent wide-angle beam scanning characteristics.
