1. An electronically scanned array (ESA) antenna comprising:
a radiating element layer comprising a plurality of radiating elements;
an integrated circuit board layer comprising a plurality of beamforming integrated circuits; and
a filter layer comprising a plurality of filters, each filter comprising:
a first via in electronic communication with a corresponding radiating element; and
a second via in electronic communication with a corresponding beamforming integrated circuit,
wherein:
the filter layer is disposed between the radiating element layer and a routing layer, the routing electrically connecting one terminal of each filter with a radiating element in the radiating element layer and electronically connecting another terminal of each filter with the integrated circuit board layer.
