Terahertz image sensors have large potential in time-domain spectroscopy, radio astronomy, security control, communications, and biomedical imaging. We present a new structure for THz imaging, obtained by the combination of a CMOS photodetector, and a rectennas composed by a tapered μ-helix monopole and a rectifying device. The antenna consists in a truncated conical helix extruded from a planar spiral and in a nanometric metallic whisker connected to one of its edges. We introduce the new structure together with an accurate study of the effect of electric field enhancement and of parasitic elements which affect the overall sensitivity of the device.
