THz leaky lens antenna coupled KIDs for broadband imaging and spectroscopy

This contribution presents the first demonstration of a linear polarized ultra wide bandwidth antenna, the Leaky Lens Antenna, coupled to a Kinetic Inductance Detector (KID). The two of them function as an ultra sensitive receiver over a bandwidth ranging from 0.15 GHz to 1.5 THz. The system has been manufactured and characterized in terms of power efficiency, and radiation pattern properties. The agreement between the expectations and the measurements is excellent.
