Terahertz antenna for arrays of hundreds of pixels

Array technology is currently being applied to terahertz (THz) remote sensing systems to improve sensitivity and scanning speed. An integral component to these arrayed systems is the antenna feed structures since they must satisfy challenging manufacturing requirements to support the high densities and high pixel counts required. This paper reviews the current technologies used for THz antennae and discusses their impediments to arraying. Several new antenna designs are efficiently arrayed are discussed.
