Glide-Symmetric Pin Phase Shifter implemented in Gap-Waveguide Technology Palomares-Caballero, Ángel Alex-Amor, Antonio Valenzuela-Valdés, Juan Francisco Luna-Valero, Francisco Padilla-de-la-Torre, Pablo Ondas This paper presents a compact and low-loss waveguide phase shifter based on a pin lattice in glide- symmetric configuration. There is a significant increase in provided phase shift when using a glide-symmetric pin distribution instead of a non-glide-symmetric configuration. A prototype has been manufactured to validate the simulated results of both phase shifters: non-glide-symmetric and glide- symmetric designs. Gap-waveguide technology has been implemented for low-cost manufacturing. The measurement results demonstrate the higher performance and compactness of the glide-symmetric phase shifter. For the same phase shifter length, the glide-symmetric design provides around 80 degrees more of phase shifting compared to the non-glide-symmetric phase shifter. Both phase shifters have a good impedance matching between 46 and 60 GHz (better than -10 dB) and an insertion loss lower than 1 dB. 2019-09-10T08:21:55Z 2019-09-10T08:21:55Z 2019 2019-09-10 conference output https://hdl.handle.net/10630/18286 eng XXXIV Simposio Nacional de la Unión Científica Internacional de Radio (URSI 2019) Sevilla, España 04/09/2019 http://creativecommons.org/licenses/by/4.0/ open access Atribución 4.0 Internacional
