(2024) A metasurface-enhanced substrate-integrated waveguide antenna. IEEE Access, 12, 62448-62458. https://doi.org/10.1109/ACCESS.2024.3394698.2169-353610.1109/ACCESS.2024.3394698https://academica-e.unavarra.es/handle/2454/51578The design, manufacture and characterization of a slotted waveguide antenna using substrate-integrated waveguide (SIW) technology combined with a metasurface are described in this paper. The inclusion of the metasurface serves to augment the radiating aperture and narrows the E-plane cut of the antenna pattern, a characteristic that would otherwise be dictated by the slots. For demonstration, an 8-element slotted SIW (S-SIW) antenna array with a -20 dB sidelobe level Chebyshev distribution was designed and its performance was compared to that of a conventional slotted SIW array. Owing to the metasurface, the radiation pattern E-plane narrows and 3 dB gain improvement has been achieved, while keeping matching unaffected.application/pdfeng© 2024 The Authors.
