Abstract: The system and method for an additively manufactured radome for a cavity backed notch comprising at least one lattice structure wherein the antenna works over any 4:1 bandwidth, from VHF to mmW. In some cases, the radome lattice has a density that changes with distance from the antenna. In some cases multiple antennas are used for direction finding. The radome may be additively manufactured from glass-loaded polymer or other materials having a low dielectric constant. In some cases, the radome has a dielectric contract that approaches that of air.

Abstract: The system and method making and using a modular, scalable phased array antenna particularly for use on curved substrates. Surface resistors are used instead of vias to reduce the cost and to increase the configurability of the array. The array is frequency independent and can be used on flat or curved surfaces. The array can be printed as a PCB or printed using additive manufacturing.

Abstract: The system and method for a conformal millimeter wave (mmW) cavity backed slot antenna with near positive gain and hemispherical gain coverage. The antenna has a microstrip launch and feed and a surface mount connector. The mmW antenna may have a stripline launch or waveguide launch instead of a microstrip launch. In some cases, the microwave electronics can be mounted on the launch substrate instead of a connector.
