Mejora de antenas metalo-dieléctricas en la banda de frecuencias GSM-UMTS mediante elementos en transmisión extraordinaria
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
Implementacion de línea de ε negativa en tecnología stripline
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
Evalución de dosimetría de campos electromagnéticos en el entorno interior doméstico
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the evaluation of radiofrequency
exposure in a domestic environment is analyzed. 3D raytracing
simulation results are compared with dossimetry measurement
results in a probe household in a dense urban area ...
Análisis del comportamiento de esquemas de modulación adaptativos en LTE
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the behaviour of several modulation
schemes used in 3GPP R8 or Long Term Evolution (LTE)
Systems is analyzed. In order to increase the capacity of future
mobile networks, high order modulation schemes like ...
Polarization-tunable negative or positive refraction in self-complementariness-based extraordinary transmission prism
(EMW Publishing, 2010)
Artículo / Artikulua,
Here we report a prism made of stacked quasi-selfcomplementary extraordinary transmission surfaces which allows simultaneously left- and right-handed propagation within the V-band for vertical and horizontal polarizations, ...
Ultra-wideband metamaterial filter based on electroinductive-wave coupling between microstrips
(EMW Publishing, 2009)
Artículo / Artikulua,
In this work, we analyse the frequency response of
microstrip lines coupled by complementary split ring resonators
(CSRRs) etched on the ground plane supporting electroinductive
waves (EIWs). The single-particle ...
Analysis of bluetooth-based wireless sensor networks performance in hospital environments
(MDPI, 2016)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, a method to analyze the performance of Bluetooth-based Wireless Sensor Networks (WSN) deployed within hospital environments is presented. Due to the complexity that this kind of scenarios exhibit in terms of ...
Double-port slotted-antenna with multiple miniaturized radiators for wideband wireless communication systems and portable devices
(Electromagnetics Academy, 2019)
info:eu-repo/semantics/article,
Proof-of-concept is presented of a novel slot antenna structure with two excitation ports. Although this antenna provides a wide impedance bandwidth, its peak gain and optimum radiation efficiency are observed at its ...
Band-pass filter-like antenna validation in an ultra-wideband in-car wireless channel
(Institution of Engineering and Technology (IET), 2015)
info:eu-repo/semantics/article,
Ultra-wideband (UWB) is a very attractive technology for innovative in-car wireless communications requiring high data rates. A designated antenna, which presents a reflection coefficient (S11) matched band comparable to ...
Wideband printed monopole antenna for application in wireless communication systems
(IET, 2018)
info:eu-repo/semantics/article,
Empirical results of an electrically small printed monopole antenna are described with a fractional bandwidth of 185% (115 MHz to 2.90 GHz) for return-loss better than 10 dB, peak gain and radiation efficiency at 1.45 GHz ...
