Abstract

A compact Line Source Generator (LSG) consisting of a flat lens is proposed in this paper. The flat lens is used to transform a cylindrical wavefront generated by the horn to a planar wavefront which provides a uniform phase distribution in the output aperture. Unlike the conventional convex lens whose design is based on Geometrical Optics (GO), the flat lens is designed based on the Field Transformation (FT) method. By optimizing the permittivity of the center layer and two matching layers, the phase compensation for wavefront transformation is achieved, together with good impedance match over a wide band. A Continuous Transverse Stub (CTS) antenna with a low profile is designed by using the proposed LSG.
