Abstract :
This contribution presents the design of a dual polarized leaky lens antenna. This antenna is fed by a CPW, which will make part of a Kinetic Inductance Detector (KID) in order to enable a broadband THz detector for future space applications. A parametric study on the lens geometry has also been performed by means of varying the extension length and it is optimized to achieve optimum aperture efficiency. The designed leaky lens antenna presents high efficiency and clean symmetric patterns in both polarizations.
