Chessboard Focal Plane Array for a CMOS-Integrated Terahertz Camera

This article presents the development of a focal plane array (FPA) for terahertz imaging applications with a near diffraction-limited resolution achieved through a very tight sampling of the focal plane. The antenna array is integrated with direct detectors in a 22-nm CMOS technology and operates from 200 to 600 GHz. The tight sampling of the...

Beam Scanning of Silicon Lens Antennas Using Integrated Piezomotors at Submillimeter Wavelengths

This paper presents a lens antenna that scans the beam using an integrated piezomotor at submillimeter-wave frequencies. The lens antenna is based on the concept presented by Llombart et al. in 2011, a leaky-wave waveguide feed in order to achieve wide angle scanning and seamless integration with the receiver. The lens is translated from the...

BiCMOS integrated waveguide power combiner at submillimeter-wave frequencies

This contribution presents the development of an integrated power combiner in Bi-CMOS technology employing artificial dielectric layers (ADLs) at submillimeter wave frequencies. The power is gathered from frequency multiplier chains into a single waveguide which is loaded with ADL in order to reduce the structure footprint.
