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.

Building block for space-based phased array

A gate-hinge bracket for fastening to a gate post has a J-bolt and a mounting plate. The J-bolt has an elongated threaded shank and a generally perpendicular pintle. The mounting plate has an internally-threaded socket for coupling with the threaded shank portion of the J-bolt. It further has a plurality of fastener openings for fastening it to the gate post by fasteners. Thus, the J-bolt can be twisted relative to the stationary mounting plate until the pintle portion is aligned on a chosen axis. Optionally there is a lock nut on the threaded shank between the pintle and the mounting plate in order to lock the pintle in a fixed position. Optionally the gate post is tree trunk or slice thereof bored with an enlarged clearance bore for the shank of the J-bolt, as well as with pilot holes for fasteners like lag screws.
