Abstract
A radiation sensor for centimeter, millimeter or sub-millimeter waveband receiption, comprising a metal antenna located close to a supporting dielectric body of intermediate to high dielectric constant value and having a mixer located in between and connected to the limbs of the antenna. The supporting body may itself be of semiconductor material, or if of insulating dielectric material, semiconductor material may be incorporated adjacent the antenna; and the mixer components, diodes, integrated in the semiconductor material. Antennae, as above, may be arranged in close-packed array, and the supporting body configured as, or as part of, a lens.
