  • Publication number: 20250125524
    Abstract: Systems and methods relating to multi-beam forming networks using an antenna array. A matrix circuit for feeding elements of an antenna array to produce multiple beams is provided. To address beam squint issues, beam squint is mitigated by using a series of phase shifters with specific phase-delay performances between the matrix circuit and the antenna array elements. A linearly increasing or decreasing phase difference in the signals fed into adjacent antenna array elements across the array mitigates or eliminates beam squint in the resulting multiple beams. The phase shifters are programmed to provide this increasing or decreasing phase differences.
