Terahertz antenna compatible with CMOS array detector for a real-time T-ray imaging system

This paper reports a miniaturized patch antenna capable of detecting multi-frequencies in conjunction with CMOS detector arrays for real-time imaging in THz-band. The proposed antenna is designed at three-bands of 218, 338 and 400 GHz corresponding to the atmospheric transmission windows. And the performance of the triple-band THz antenna is demonstrated using the finite-difference time-domain method.
