Design of terahertz frequency scanning reflector antenna and its application in direction-of-arrival estimation

A novel frequency scanning-based direction-of-arrival (DOA) estimation scheme is proposed at terahertz (THz) band. The diffraction enhancement mechanism, focusing the superposition of the diffracted beam radiated from each element in one unit cell, is expanded to the 0.3 THz band. The frequency scan...
