A 280GHz CMOS on-chip composite right/left handed transmission line based leaky wave antenna with broadside radiation

Abstract

A 280GHz leaky wave antenna with broadside radiation is demonstrated by 13-unit-cell periodic composite right/left handed transmission line (CRLH-T-Line) in 65nm CMOS with stacking high-resistivity dielectric layer to enhance antenna radiation efficiency. The design is fabricated in CMOS 65nm process and verified by measurement in THz region from 220 to 325 GHz.
