Gain-Reconfigurable Hybrid Metal-Graphene Printed Yagi Antenna for Energy Harvesting Applications
Alex-Amor, Antonio; Palomares-Caballero, Ángel; De la Fuente, Elena; Muriel-Barrado, Alfonso; Valenzuela-Valdés, Juan Francisco; Fernández-González, José M.; Padilla, Pablo[et al.] (2019-04-26)This paper presents a hybrid metal-graphene printed Yagi antenna with reconfigurable gain that operates in the 5.5-GHz band. The balun and the driven elements are made of copper, while the directors are made of graphene. ... -
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 (2019-09-10)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 ... -
Phase Shifter for Millimeter-Wave Frequency Range Based on Glide Symmetric Structures
Palomares-Caballero, Ángel; Alex-Amor, Antonio; Valenzuela-Valdés, Juan Francisco; Luna, Francisco; Padilla, Pablo (2019-03-13)The use of glide symmetry in radiofrequency devices to introduce dispersive effects has been recently proposed and demonstrated. One of these effects is to control the propagation constant of the structure. Here, we propose ...
