Abstract: The one-dimensional Fresnel zone phase correcting principle can be applied in a cylindrical surface to constructed a new type of point source feeding lens antenna. In this paper, the auxiliary source method is used to evaluate the focused fields of this new lens antenna under arbitrary plane wave incidence, placing emphasis on the analysis of the paraxial scanning performance and frequency properties of the focused fields. -
