Full-Wavelength Dipole Antenna on a GaAs Membrane Covered by a Frequency Selective Surface for a Terahertz Photomixer

The TeraHertz (THz) frequency region, which is loosely defined as 0.1-10THz, has long been known as "The THz gap" although THz science and technology have made significant progress in the past decades. An antenna consisting of a full-wavelength dipole on a GaAs membrane covered by a frequency selective surface is proposed for improved output power from photo-mixers used as THz sources. The antenna structure reduces the vertical dimension of a typical photo-mixer antenna using a substrate lens while still exhibiting high total efficiency and high directivity.
