    Wideband circularly-polarized gap waveguide-based antenna design
    (IEEE, 2025-03-12) Leoz-Beltrán, Iñigo; Iriarte Galarregui, Juan Carlos; Pérez Quintana, Dayan; Teberio Berdún, Fernando; Beruete Díaz, Miguel; Ederra Urzainqui, Íñigo; Ingeniería Eléctrica, Electrónica y de Comunicación; Ingeniaritza Elektrikoa, Elektronikoa eta Telekomunikazio Ingeniaritza
    This paper presents the design of an all-metal antenna based on Gap Waveguide technology. The antenna, which is realized using a Ridge Gap Waveguide, consists of just two layers, maintaining a compact size. The first layer is made up of two perpendicularly placed arms, which comprise the feeding, and the second layer hosts a diamond shaped slot and a horn, which comprise the radiator. Simulations show that the design achieves a remarkable bandwidth equivalent to the 31.43% of the central frequency in terms of both S11 parameter, being below -10 dB, and Axial Ratio, being below 3 dB.
