1. An imaging device to be used with millimeter and/or sub-millimeter radiation comprising at least a pair of substrates, at least one of which is patterned on at least one surface with a patterning defining at least one radiation detector, each radiation detector comprising:
an antenna adapted to receive millimeter and/or sub-millimeter electromagnetic radiation,
a mixer channel coupled to said antenna and in communication with a via extending through the substrate for connection to a signal output, a mixer comprising filters being mounted in the mixer channel for extracting an intermediate frequency signal in dependence upon said radiation received by the antenna,
a waveguide structure coupled to said mixer and having a signal input for connection to a local oscillator, wherein the mixing channel intersects the local oscillator waveguide at an acute angle.
