Electronics and filter-integrated, dual-polarized transition and radiator for phased array sensors

A waveguide antenna array comprising:

• a plurality of filter layers arranged in a stacked-construction forming a plurality of radiating elements arranged in an array, wherein each layer of the plurality of filter layers is a discrete component, wherein each radiating element comprises:
• a waveguide section having a first end and second end, wherein the waveguide section is configured to propagate electromagnetic energy, wherein the waveguide section for each radiating element is included in a first layer of the plurality of filter layers;
• a feed configured to launch an electromagnetic wave into the first end of the waveguide section, wherein the feed for each radiating element is included in the first layer of the plurality of filter layers;
• a waveguide filter comprising at least one resonant waveguide cavity coupled to the second end of the waveguide section, wherein the waveguide filter is configured to pass a first set of electromagnetic frequencies and reject a second set of electromagnetic frequencies, wherein the waveguide filter for each radiating element is included in a second layer of the plurality of filter layers;
• and
• an antenna coupled to the waveguide filter configured to radiate a portion of the electromagnetic energy passed by the waveguide filter, wherein the antenna for each radiating element is included in a third layer of the plurality of filter layers;
• wherein, the feed of each radiating element has an associated rotation based on a location of the antenna in the array.
