Abstract

The design of a dual polarized Leaky Lens Antenna is discussed. Its performance in case of two possible feeding structures consisting of either a microstrip or a coplanar waveguide is examined. The aperture efficiency is optimised by means of a parametric study concerning variable extension lengths. The optimised LLA shows high efficiency and clean symmetric patterns in both polarisations. The resulting antenna is intended to be integrated with a Kinetic Inductance Detector, this approach yielding a broadband THz detector with high potential for future space applications.
