Abstract: An antenna array includes multiple array modules. Each array module includes at least on antenna element including a horn antenna coupled to a polarizer, and a two-piece waveguide filter. The two-piece waveguide filter includes a folded-back waveguide coupled to the horn antenna at one end and to a circuit layer at the other end. The horn antenna includes a multi-mode horn antenna. The two-piece waveguide filter includes a first piece and a second piece that are separately molded. A footprint of the two-piece waveguide filter is within a footprint of an aperture of the horn antenna.

Abstract: Provided herein are various magnetoelectric dipole antenna arrays and multi-array arrangements for handling radio frequency signals. In one example, an antenna array includes a baseplate conductively coupled to sets of plate elements by support members that position the plate elements at selected distances offset from a surface of the baseplate. Antenna probes are arranged in orthogonal pairs positioned within gaps between a corresponding set of plate elements, with each antenna probe comprising a conductive strip having a feed section coupled to a radio frequency connection through the baseplate, a transverse section generally parallel with the baseplate, and a terminal section directed back toward the baseplate. Dielectric structures for each pair of antenna probes comprise a dielectric material having channels that recess the conductive strips therein and a dielectric spacer positioned between overlapping transverse sections of the antenna probes.

Abstract: An apparatus includes an aperture layer coupled to a polarizer layer. The aperture layer includes an antenna and a filter. A circuit layer is mechanically and thermally coupled to the aperture layer. The antenna includes a square horn antenna made of a polymer material. The filter includes a waveguide filter having a first and a second piece separately molded. The waveguide filter includes a folded-back waveguide coupled to the horn antenna at one end and to the circuit layer at another end.

Abstract: Provided herein are various enhanced assemblies and techniques for forming high-power radio frequency coaxial splitters. In one example, an apparatus includes an input coaxial port having a center conductor coupled to a first longitudinal end of a generally cylindrical conductor member formed along a longitudinal axis within a housing forming a cavity about the conductor member. Output coaxial ports are included having center conductors coupled to generally square output branches arrayed at a second longitudinal end about the conductor member in a plane perpendicular to the longitudinal axis. A thermal shunt is included comprising a thermal connection between the housing and a recess formed into the conductor member along the longitudinal axis at the second longitudinal end.
