Abstract

This paper presents the first demonstration of the applicability of the leaky lens antenna concept at THz frequencies. The antenna is integrated with a Kinetic Inductance Detector, so that the two of them function as an ultra sensitive detector over a bandwidth ranging from 0.15 to 1.5 THz. The system has been manufactured and characterized in terms radiation pattern properties and frequency response. We find that the measurements agree very well with the calculations. This demonstrates the manufacturability of the Leaky Lens for use at THz frequency, opening the possibilities for novel broad-band detection concepts.
