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.

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 antenna elements may be arranged into an antenna array that is tunable to collectively generate or receive RF signals to and from airborne and mobile vehicles with an agile, electronically scanning antenna array beam, with no moving parts. The antenna array includes a top section to communicate RF signals; a bottom section to generate a desired RF signal; and a foam layer between the top and bottom sections to separate the ring patch from the ring slot. High isolation between the top section and the bottom section allows the antenna elements to be used in higher gain and high-power arrays without adverse feedback issues.

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.
