Features include ease of fabrication and wide range of operating frequencies. Planar antennas on thick dielectric substrates built for use at millimeter wavelengths from 40 to 400 GHZ. Antennas of this type quasi-optical structures, for which expensive, precisely machined waveguides not required. Made easily by standard photolithography and integrated with planar mixers or detectors to form arrays.
