Towards sub-meter level UWB indoor localization using body wearable sensors
(IEEE, 2020)
info:eu-repo/semantics/article,
Thanks to its ability to provide sub-meter level positioning accuracy, Ultrawideband (UWB) has found wide use in several wireless body area network (WBAN) applications such as ambient assisted living, remote patient ...
Multimode HMSIW-based bandpass filter with improved selectivity for fifth-generation (5G) RF front-ends
(MDPI, 2020)
info:eu-repo/semantics/article,
This article presents the detailed theoretical, simulation, and experimental analysis of a half-mode substrate integrated waveguide (HMSIW)-based multimode wideband filter. A third-order, semicircular HMSIW filter is ...
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 ...
Optimized wireless channel characterization in large complex environments by hybrid ray launching-collaborative filtering approach
(IEEE, 2017)
Artículo / Artikulua,
Simulation techniques based on deterministic methods such as Ray Tracing and Ray Launching, are widely used to perform radioplanning tasks. However, the quality of the simulations depends on the number of rays and the ...
Analysis of wireless sensor network topology and estimation of optimal network deployment by deterministic radio channel characterization
(MDPI, 2015)
Artículo / Artikulua,
One of the main challenges in the implementation and design of context-aware
scenarios is the adequate deployment strategy for Wireless Sensor Networks (WSNs),
mainly due to the strong dependence of the radiofrequency ...
