Abstract
Provided herein are various enhancements for radio frequency (RF) horn antenna systems and arrays. An example apparatus includes a horn antenna array formed in a single workpiece of material comprising horn antenna elements with integrated feed networks. Each of the integrated feed networks comprise a waveguide interface flange having a port, and a filter element having a serpentine cavity coupled to the port that is at least partially formed by a base section, where a separation interface is established between the base section and an attachable cap that forms a remainder of the serpentine cavity. Each of the integrated feed networks also comprise a polarizer element having a waveguide cavity that couples between the serpentine cavity of the filter element and an associated horn antenna element that forms a signal aperture.
