An apparatus and method for producing a low loss printed circuit board (PCB). The PCB includes an antenna patch, a ground plane, and a polarizer. The antenna patch consists of a plastic base having a first plurality of circuit patterns formed directly on its top surface. The ground plane is formed directly on a bottom surface of the plastic base used for the antenna patch, and contains one or more coupling circuit patterns. A polarizer spacer is provided on the antenna patch to provide separation from the polarizer. The polarizer also consists of a second plastic base having a second plurality of circuit patterns formed directly thereon.

A method for providing frequency selective surface zoning includes selecting a location for positioning a frequency selective surface (FSS) panel along a support arm of a reflector antenna system, and positioning a second feed horn on the support arm on an opposite side of the FSS panel. A number of unit cells are used to populate the FSS panel, and metallic patterns are formed on each unit cell. Multiple zones are subsequently defined on the surface of the FSS panel. Each zone is optimized for a predetermined range of incident angles.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for producing meander-line polarizers. In some implementations, a meander-line polarizer includes a dielectric substrate made of a polyester polymer material and meander-line arrays formed on a surface of the dielectric substrate. Each meander-line array includes a sequence of alternating perpendicular conductive traces that are formed the surface of the dielectric substrate by applying conductive ink to the surface of the dielectric substrate using a template that defines a location and dimensions of each conductive trace of each meander-line array.

Additive manufacturing techniques for meander-line polarizers

Various antenna systems are presented that have independently steerable receive and transmit beams. The antenna system may include multiple antenna element systems. Each antenna element system may include multiple phase shifters that alter the phase of received signals and signals to be transmitted. Directions of a first transmit beam, a second transmit beam, a first receive beam, and a second receive beam may be steered independently using the phase shifters. Each antenna element system may include a polarization system.
