Sidelobe suppression of mesh reflector antenna by non-regular intervals

A suppression technique for the grating lobe level due to periodic surface error is proposed. This technique requires making divisions in the radial direction at non-regular intervals. Calculations show that this suppresses the grating lobe efficiently. The radiation pattern shows that practical rates of division can be obtained. This technique effectively suppresses the sidelobe level without changing any fundamental components. such as the number of divisions and the number of parts.<>
