In this paper, we first synthesize a current sheet from a given radiation pattern using inverse equivalent current method and then realize the current sheet using an aperiodic array of microstrip patches. Specifically, we try to reproduce the radiation pattern of a given reflector-horn system by planar array of microstrip patches. Since the resulting array is truly aperiodic in nature, so no grating lobe arises.
