We have designed a novel sub-mm radiation detector based upon a twin slot antenna placed in the focus of a Si elliptical lens. We use a novel Electromagnetic Band Gap (EBG) super-layer, consisting of 2 ¼ lambda dielectric layers of Si (epsilon = 11.7) and SiO2 (epsilon = 4) and a Si carrier wafer to enhance the directivity of the feed. The antenna is coupled to a Kinetic Inductance Detector, KID, an extremely sensitive cryogenic radiation detector operating at 300 mK or lower temperatures. We present the design, implementation and measurements of the full detector, including optical sensitivity, frequency response and beam pattern.
