Diseño de un filtro de perfil continuo en una guía coaxial vacía integrada en sustrato

Gómez Domínguez, Darío (Universitat Politècnica de València, 2017-11-30)

Recientemente se está investigando mucho en líneas de transmisión integradas en sustrato. Éstas proporcionan ventajas frente a la tecnología planar clásica (menores pérdidas, mejores factores de calidad), y mantienen su ...
Dual Composite Right-/Left-Handed Coplanar Waveguide Transmission Line Using Inductively Connected Split-Ring Resonators

Belenguer Martínez, Ángel; Cascón López, Joaquín; Lucas Borja, Alejandro; Esteban González, Héctor; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers (IEEE), 2012-10)

In this paper, a simple geometrical modification of the well-known split-ring resonator (SRR) topology is proposed. This modification consists of joining the opposite sides of the rings by means of an inductive connection. ...
Efficient and Accurate Design of Passive Devices in Substrate Integrated Waveguide Technology and their Tapered Transitions from Microstrip Lines

Díaz Caballero, Elena; Miralles, Enrique; Esteban González, Héctor; Belenguer Martínez, Ángel; Boria Esbert, Vicente Enrique; Bachiller Martin, Maria Carmen; Morro Ros, José Vicente; Lucas Borja, Alejandro (2011)

Empty SIW Technologies: A Major Step Toward Realizing Low-Cost and Low-Loss Microwave Circuits

Belenguer, Angel; Esteban González, Héctor; Borja, Alejandro L.; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers, 2019-03)

[EN] Substrate-integrated circuits (SICs) [1] have attracted much attention in the last several years because of their great potential. The first implementation of the concept can be found in [2] as a feeding mechanism for ...
Highly efficient heterogeneous modal superposition method for the full-wave analysis of arbitrarily shaped H-plane structures fed through rectangular waveguides

Belenguer Martínez, Ángel; Esteban González, Héctor; Boria Esbert, Vicente Enrique; Lucas Borja, Alejandro; Cascón López, Joaquín (Institution of Engineering and Technology (IET), 2011-05-13)

A new fully modal characterisation procedure is proposed to reduce the number of unknowns needed to characterise the ports of an arbitrary H-plane device in rectangular waveguide, so that no equivalent currents will be ...
