The concepts, systems, circuits and techniques described herein are directed toward a spiral antenna which may be provided using additive manufacturing technology so as to provide an antenna capable of operation at frequencies which are higher than spiral antennas manufactured using standard photo-etch or printed circuit board (PCB) manufacturing processes.

Spiral antenna and related fabrication techniques

A wave phased array is manufactured using additive manufacturing technology (AMT). The wave phased array includes a radiator, a radiator dilation layer supporting the radiator, a beamformer supporting the radiator dilation layer, a beamformer dilation layer supporting the beamformer, and a substrate support layer supporting the beamformer dilation layer. At least one of the radiator, the radiator dilation layer, the beamformer, the beamformer dilation layer and the substrate support layer is fabricated at least in part by an AMT process.

Millimeter wave phased array

A reactive beamformer includes a radiator disposed within a substrate and configured to radiate a received electromagnetic signal, a plurality of receptors disposed within the substrate, each of the plurality of receptors configured to receive a portion of the radiated electromagnetic signal, and a plurality of signal lines. Each signal line of the plurality of signal lines is coupled to a respective receptor of the plurality of receptors to convey the portion of the radiated electromagnetic signal from the respective receptor and to provide the portion of the radiated electromagnetic signal to an output.

Additive manufactured reactive beamformer

Described herein is a low profile radiator (LPR) manufactured using additive manufacturing technology (AMT). Such an AMT radiator is suitable for use in an array antenna which may be fabricated using AMT manufacturing processes.

Additive manufacturing technology (AMT) low profile radiator

A device and process are disclosed for indicating clearance requirements of an aircraft maneuvering on a surface such as an apron, taxiway or flight deck. The device has an electromagnetic generation mechanism for generating a high intensity, low diffusing electromagnetic beam, and a projecting mechanism for securing the electromagnetic generation mechanism to the aircraft and projecting the beam toward a projection region. The projection region extends axially and in alignment with the distal end, and from the surface upward. In one embodiment, the electromagnetic generation mechanism is a laser that outputs a laser beam in the visible light spectrum. The beam produces an image upon the surface within the projection region, or upon an obstacle in the aircraft's path. Thus, the pilot can ascertain the clearance requirements by observing the projected images on the runway surface. Any object protruding within the space demarcated by the images represents an obstacle in the aircraft's path, and the pilot can alter course accordingly to avoid it.
