Abstract: A quasi-optical antenna system is designed for terahertz active standoff personnel screening in this paper. The design principle of the quasi-optical antenna is described in detail according to actual needs. The results from GRASP software shows that the system can achieve 10 mm imaging resolution over a 28 × 24 cm field of view at 2 m with a center frequency 180 GHz. it has the potential to be used in active terahertz standoff personnel screening.
