Abstract :
The design, fabrication and characterisation of a 500 GHz electromagnetic bandgap (EBG) based heterodyne receiver array is presented. The array contained seven planar dipole antennas that were photolithographically defined on a common 20 mum thick quartz substrate. Each antenna incorporated a Schottky diode and was connected to coplanar transmission lines that conveyed the down converted 500 GHz signals to detectors. The quartz substrate was backed by a silicon EBG woodpile structure, which reduced antenna cross talk and increased directivity. An off-axis parabolic mirror completed the beam forming network.
