US Patent 10938120 Planar antenna with integrated low noise receiver

A planar antenna with an integrated receiver based on aperture coupled antenna elements with inclusive slots electrically coupled to a microstrip feed network residing above a lower ground plane is disclosed. The use of aperture coupled feed elements eliminate the need for vias, which simplifies fabrication. Further, the antenna has integrated electronics located on the same layer as the microstrip feed network to minimize any noise or unwanted parasitic effects.
