A terahertz quasi-optical detector (QOD), consisting of a rectenna chip and a dielectric lens, is presented in this paper. The rectenna is a log-periodic antenna with a Schottky diode at the center, which is fabricated on GaAs substrate. A low cost dielectric lens is designed based on 3D printing technology. By using MLFMM algorithm, the dimensions of the 3D printed lens is optimized for maximum directivity of the antenna on chip.
