Abstract: A method and apparatus for a polarizer. The apparatus comprises a dielectric rod, a first array of slots, and a second array of slots. The first array of slots and the second array of slots are formed in sidewalls of the dielectric rod. The first array of slots is substantially opposite to the second array of slots. The first array of slots and the second array of slots are configured to shift a first component orthogonal to a second component in a signal traveling through the dielectric rod by around 90 degrees with respect to each other. The dielectric rod may be a solid material or comprised of layers of dielectric substrates with metal tabs.

Abstract: An antenna array core comprising a plurality of microwave modules, a control layer, a mounting layer, and a signal distribution layer. The control layer is capable of distributing control signals to the plurality of microwave modules. The plurality of microwave modules are attached to an upper surface of the mounting layer and the mounting layer is made from a heat conductive material capable of cooling the plurality of microwave modules. The signal distribution layer is located below the mounting layer, wherein the signal distribution layer is capable of transmitting microwave signals to the plurality of microwave modules and wherein the arrangement of the plurality of microwave modules on the mounting layer, the control layer, and the wave distribution network form a layered architecture for the antenna core. The architecture is a balance between, size, thermal control, manufacturability, cost, and performance so as to be a unique solution.
