A new integrated lens-antenna is designed and implemented for a nanocontact based terahertz (THz) photomixer. The new design replaces the standard conventional bulky silicon lens, which normally no THz device can avoid. The Fresnel Zone Plate (FZP) is used to design the new lens-antenna and is simulated on the MIT open-source tool called Meep. The final design showed, with only two simple fabrication technology processing steps (normal optical lithography) that the lens-antenna can be implemented including the THz photomixer. The simulation and the fabrication results showed promising results towards the THz measurements, compared with the conventional bulky silicon lens.
