Abstract: A method and moments (MoM) and closed-form Green's function approach are employed in this letter to characterize the radiation pattern of a center-fed helical microstrip antenna mounted on a superstrate of a circular conducting cylinder. An analytic expression of current on the helical microstrip antenna is rigorously obtained by solving mixed potential integral equation (MPIE) in spatial domain. With the analytic expression of the current, radiation patterns of the helical antenna can be analytically calculated using far-field Hankel transform. The proposed method can be easily applied to analyze the effects of substrate and superstrate on the radiation pattern of the helical antenna. A good agreement between results of the present Green's function and MoM approach and those of the reciprocity approach provides validation for the present method.
