Abstract

This paper presents a photomixer driven antenna with increased output power at continuous-wave (CW) Terahertz (THz). The antenna is supported by membrane and comprised of a horn cavity for enhancing radiation. With improved impedance matching to the source (photomixer), the output power of this antenna is greatly enhanced compared with the existing antenna with 2-μW output power at 1 THz. The proposed antenna eliminates the usage of any lens and demonstrates a good candidate for high power CW THz source.
