Array consisting of disk-coupled resonant directive antennas
Abstract
A high-gain low-sidelobe array consisting of disk-coupled resonator directive antennas is analyzed using the approximation theory that is based on the induced current method. The calculation result for the radiation pattern of the array within the main lobe is found to be more accurate than that obtained by using the array factor. Also discussed are the sidelobe suppression effect by uneven spacing excitation and the effect of the reflector sizes. The characteristics of the ground-station antenna for use in satellite and rocket communications are analyzed.
