Radio characterization for ISM 2.4 GHz wireless sensor networks for judo monitoring applications
(MDPI, 2014)
Artículo / Artikulua,
In this work, the characterization of the radio channel for ISM 2.4GHz Wireless Sensor Networks (WSNs) for judo applications is presented. The environments where judo activity is held are usually complex indoor scenarios ...
Development of a low mobility IEEE 802.15.4 compliant VANET system for urban environments
(MDPI, 2013)
Artículo / Artikulua,
The use of Vehicular Ad-Hoc Networks (VANETs) is growing nowadays and it includes both roadside-to-vehicle communication (RVC) and inter-vehicle communication (IVC). The purpose of VANETs is to exchange useful information ...

(American Institute of Physics, 2017)
Artículo / Artikulua,
In this work, the behavior of a Complementary Split Ring Resonator (CSRR) operating within the
quasi-static resonance regime and embedded in a composite stratified Substrate Integrated
Waveguide (SIW) with two different ...
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, ...
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 ...
