  • Phased array antenna system utilizing a beam forming network
    Patent number: 7609210
    Abstract: In accordance with an embodiment, a phased array antenna system includes a printed wiring board formed in rhombic shape that accommodates requirements for low observability and a beam forming network located within the printed wiring board. The beam forming network is located over substantially the entire printed wiring board. The embodiment includes connectors located on the backside of the printed wiring board. The back side connectors allow the array architecture to expand to include more subarrays and therefore allowing for more beam forming elements in a full size array than conventional phased arrays.
