A recently granted patent (Publication Number: US11843181B2) discloses an aviation antenna assembly designed for aircraft communication systems. The assembly includes a radome attachable to the aircraft body, multiple antenna elements, directional control switches for transitioning between transmission and reception modes, beam forming network elements, and an electronically controlled phased array stirring assembly. This stirring assembly, housed within the radome, consists of a digital signal processor (DSP) and a field programmable gate array (FPGA) connected via a control bus. The system also features specific configurations in the transmit and receive chains, including high power amplifiers, beam forming network circuits with amplitude attenuation and phase shifter circuits, and path isolation circuits with combiners for signal processing.

Furthermore, the patent details the digital control capabilities of the FPGA in managing the phase shifters and amplitude attenuation circuits in both the transmit and receive chains. The receive chain is equipped with low noise amplifiers positioned strategically before band pass filters and path isolation circuits for signal optimization. The antenna assembly's design allows for efficient signal transmission and reception, with each antenna element having its own transmit and receive chain instances. The system's architecture, with the DSP and FPGA controlling critical functions, ensures precise control over signal processing and beam forming, enhancing the overall performance of the aviation antenna assembly for reliable communication in aircraft applications.
