MINIATURE PHASE-CORRECTED ANTENNAS FOR HIGH RESOLUTION FOCAL PLANE THz IMAGING ARRAYS

An imaging/detection device, comprising:

• a hemispherical lens having a surface opposite to a curvature of the hemispherical lens, the surface being extended away from a center of the hemispherical lens, the hemispherical lens defining an optical axis;
• and
• a plurality of detectors arranged on a focal plane array that is positioned near the surface of the hemispherical lens, each of the detectors respectively including:
• a diode, and
• an antenna monolithically integrated with the diode, wherein at least one of the detectors is offset by a distance from the optical axis of the hemispherical lens and is configured such that a radiating pattern of the respective antenna of the at least one of the detectors is tilted by an angle and directed toward the optical axis of the hemispherical lens, a maximum direction of the radiating pattern of the respective antenna of the at least one of the detectors being related to the distance by which the at least one of the detectors is offset from the optical axis of the hemispherical lens.
