Abstract
In this paper, a 0.34-THz 2 × 2 phased array
integrated circuit is presented, which demonstrates a new
approach for implementing phased arrays in the millimeter-wave
(mm-wave)/terahertz (THz) spectrum. The circuit structure con-
sists of four unit standing wave oscillators. In each cell, fun-
damental frequency ( f
0) and odd harmonics are systematically
cancelled, while the desired fourth harmonics (4 f0)a r ec o m -
bined and radiated by on-chip patch antennas. A phase-shifter-
