    Mejora de antenas metalo-dieléctricas en la banda de frecuencias GSM-UMTS mediante elementos en transmisión extraordinaria
    (2009) Illescas, Jesús; Estévez González, Aritz; Falcone Lanas, Francisco; Marcotegui Iturmendi, José Antonio; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    In this work a dual band GSM/UMTS antenna is proposed. The antenna is based on a stacked planar structure, where the combination of collimation by Enhanced Transmission and the use of parasitic director elements is used in order to achieve the desired specifications. Full wave simulation results, obtained using a self created algorithm based on the FDTD method, as well as measurement results from a fabricated prototype are presented, showing good agreement. The proposed antenna finds application in the deployment of micro and minicell sites in dual 2G/3G networks

    Implementacion de línea de ε negativa en tecnología stripline
    (2009) Illescas, Jesús; Jarauta Ayensa, Eduardo; Estévez González, Aritz; Marcotegui Iturmendi, José Antonio; Falcone Lanas, Francisco; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    In this work, a negative-ε equivalent response medium is proponed in stripline technology. To achieve band rejection behaviour, Complementary Split Ring Resonators (CSRR) are placed in the central conductor strip of a conventional stripline planar transmission line. Due to strong normal electric field incidence, adequate excitation of the stripline is achieved, leading to band rejection in the quasi-static resonance frequency of the CSRR particles. Full wave simulation results from our own FDTD code and measurement results are presented, showing good agreement.

    Compact ultra wide band microstrip bandpass filter based on multiple-mode resonator and modified complementary split ring resonator
    (Hindawi, 2013) Marcotegui Iturmendi, José Antonio; Illescas, Jesús; Estévez González, Aritz; Falcone Lanas, Francisco; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    A new class of broadband microstrip filters for Ultra Wide Band (UWB) applications is proposed. In the design, different stages of parallel-coupled microstrip line and other stages with a Modified Complementary Split Ring Resonator (MCSRR)—a concept proposed here for the first time—are adjusted to obtain the desired response with broadband, sharp rejection, low insertion loss, and low return loss. Full wave simulation results as well as measurement results from fabricated prototypes are presented, showing good agreement.Theproposed technique offers a new alternative to implement low-cost high-performance filter devices, applicable to a wide range of communication systems.
