Abstract: Millimeter-wave (mmWave) and terahertz (THz) technologies enable a large number of exciting applications, such as space exploration, high-speed communication, self-driving, non-ionizing imaging. In these and other mmWave and THz systems, antennas play key roles since they significantly affect and even directly determine the system performance and cost.

This talk presents five different antennas from PCB to Silicon, i.e., (1) 94GHz reflectarray in printed circuit board (PCB), (2) 135GHz silicon antenna fabricated by in-house BCB-Silicon process for mmWave 3DIC, (3) a horn antenna compatible with through-silicon via process for our proposed mmWave 3D SiP, (4) a substrate- integrated waveguide antenna in commercial SiGe BiCMOS process, it achieve full integration and frequency reconfigurability from 397 to 428GHz, and (5) a 315GHz antenna to be inherently integrated with graphene detector in the same high- resistivity silicon substrate.

The above research partially reviews our effort in mmWave and THz antennas, and provides a reference for mmWave/THz antennas and systems.
