A High-Power and Scalable 2-D Phased Array for Terahertz CMOS Integrated Systems

Abstract

This work introduces a 2-D phased array architecture that is suitable for high power radiation at mm-Wave and Tera- hertz frequencies. We address the challenge of signal generation above the cut-off frequency of transistors by presenting a radia- tion method based on the collective performance of a l arge number of synchronized sources. As theory shows, both frequency locking/ tuning and beam steering can be independently achieved by ma- nipulating the local coupling between the nearest neighbor
