Methods and apparatus for an antenna assembly including one or more array blocks having one or more corporate manifolds, each having an input port, a plurality of output ports, and a plurality of phase shifters, each of the phase shifters located at a respective one of the output ports. Array blocks can further include a plurality of serial manifolds each having an input port and a plurality of output ports, the input port coupled to a respective output port of one of the corporate manifolds; and plurality of antenna elements coupled to respective output port of one of the serial manifolds.

Electronically scanned array using manifolds

A method of forming a component having multiple material properties includes forming, by additive manufacturing, a particle containment structure on a base layer; filling the particle containment structure with a first layer of particles, the layer of particles being contained by the particle containment structure; curing the first layer of particles; repeating the forming the particle containment structure, filling the particle containment structure with one or more additional layers of particles and curing the one or more additional layers of particles until a desired component dimension is achieved; forming, by additive manufacturing, a cover to encapsulate any exposed particles; and fully curing the particle containment structure, particles and cover.
