Abstract: A dual ultra-wideband electronically scanning antenna linear array and a method for producing same is disclosed. In one embodiment, the antenna is comprised of circuit board-based multi-layered sections with integrated feeds. A first dielectric layer or substrate has a thin metal coating on the bottom surface to form a signal ground and metal coating on the top surface where capacitively loaded radiating dipoles are etched. Each of the dipole elements are connected to an associated conductive antenna feed disposed on a bottom surface of another dielectric layer disposed below the first dielectric layer.

Abstract: A system, method, and apparatus for an antenna system. The antenna system comprises an aperture structure, a primary radiating slot, a tuning slot, and a stripline feed. The primary radiating slot and the tuning slot are both located in the aperture structure. The stripline feed is located between the primary radiating slot and the tuning slot in the aperture structure.

Abstract: Unit cells for phased array antennas are described. The unit cells include a plurality of dipole antennas that are used to form a phased array antenna. In particular, the unit cells that form the phased array antenna each include a plurality of dipole antennas formed on a surface of a substrate that are arranged to collectively form a triangle. A plurality of the unit cells may be linked together to form a triangular lattice array having almost any desired size and aperture, thereby allowing the RF engineer the freedom to achieve a wide variety of performance goals when designing a phased array antenna.

Abstract: Antenna elements are disclosed herein that include a metallic square ring patch and a metallic square ring slot to transmit or receive radio frequency (RF) signals. The disclosed antenna elements use several dielectric layers that are separated by two low-dielectric foam layers. The square ring patch is located above an upper foam layer, and a square ring slot is located between the upper foam layer and a bottom foam layer. Electrical feed lines are used to either supply electrical power to the antenna elements cells or output RF signals that are received by the square ring patch. The disclosed antenna elements may be arranged together in an antenna array that is tunable to collectively generate or receive RF signals.

Abstract: Antenna elements include a metallic square ring patch and a metallic square ring slot to transmit or receive radio frequency (RF) signals. The antenna elements use several dielectric layers that are separated by a low-dielectric foam layer upon which the square ring patch is positioned. The disclosed antenna elements may be arranged together in an antenna array that is tunable to collectively generate or receive RF signals. In particular, the antenna array functions as a 256-element transmit/receive half-duplex antenna, operating in transmit or receive mode for half the time. The antenna array includes a radiator block, a transmit/receiver (T/R) amplifier block, a beamformer block, and a distribution network block.

Abstract: Various ring cells are disclosed herein that include a metallic ring patch and a ring slot to transmit or receive radio frequency (RF) signals. The disclosed ring cells use several dielectric layers that are separated by a low-dielectric foam layer upon which the ring patch is positioned. The ring slot is located below the foam layer. An electrically conductive fence formed curved electrically conductive walls or a circular pattern of electrical vias is positioned around the ring slot. Electrical feed lines are used to either supply electrical power to the ring cells or output RF signals that are received by the ring patch.
