    A multi-beam circularly polarised Fabry-Perot resonator antenna array using SIW for X-Band applications by Khajeh Mohammad Lou, Reza, Aribi, Tohid, Sedghi, Tohid, Virdee, Bal Singh

    Published 2025
    “…This paper presents a novel multi-layer beamforming antenna array based on Fabry-Perot resonator that is excited by a high performance compact 4 × 4 Butler matrix using substrate integrated waveguide SIW) technology for X-band application. The adapted ring patch antenna is fed through the aperture on a rectangular SIW cavity and forms the radiating element in the antenna array. …”
