A Fresnel Zone Plate Lens designed for the Mid-IR is modified for acting as a THz Antenna. This proposal is the base for a dual band detector consisting of a Silicon (Si) substrate with a quasi-spiral antenna detector working at THz frequencies which acts also as a modified Fresnel Zone Plate Lens for an IR detector. The focal properties of the proposed lens have been studied numerically, and its behavior as a submillimeter wave receiver has been demonstrated by a 3D full-wave simulator.
