Addressing the 5G cell switch-off problem with a multi-objective cellular genetic algorithm
Luna, Francisco; Luque-Baena, Rafael Marcos
; Martínez, Jesús; Padilla, Pablo; Valenzuela-Valdés, Juan Francisco (2018-07-16)
The power consumption foreseen for 5G networks is expected to be substantially greater than that of 4G systems, mainly because of the ultra-dense deployments required to meet the upcoming traffic demands. This paper deals ... -
Gain-Reconfigurable Hybrid Metal-Graphene Printed Yagi Antenna for Energy Harvesting Applications
(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. ... -
Phase Shifter for Millimeter-Wave Frequency Range Based on Glide Symmetric Structures
(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 ... -
Redes de sensores seguras y eficientes con beamforming
Valenzuela-Valdés, Juan Francisco; Luna, Francisco; Padilla, Pablo; Padilla, José Luis; Luque-Baena, Rafael Marcos (2017-07-03)
Mejorar la eficiencia energética de las redes de sensores (WSN, por sus siglas en inglés) es uno de sus principales objetivos de diseño. De entre las distintas líneas de trabajo existentes en esta área, el uso del ...
