Existing dielectric lens geometries are optimized for remote sensing applications in order to produce a predetermined Gaussian beam in the far field that is matched to a radioastronomic setup. In this work, an optics suitable for object investigation in a point-to-point transmission setup is presented. Here it is required to create a focus point outside the lens with as low radiation leakage as possible. For this, a catadioptric dielectric lens is proposed. This paper presents the theoretical performance of the focusing property of catadioptric lens investigated at 50 GHz and 228 GHz having er = 11.7. 3D simulation results of the catadioptric lens also show a focus point. Imaging property of catadioptric and extended hemispherical lenses are presented and compared at 50GHz. A Transient analysis of the lens is also presented.
