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 ...
Challenges in wireless system integration as enablers for indoor context aware environments
(MDPI, 2017)
Artículo / Artikulua,
The advent of fully interactive environments within Smart Cities and Smart Regions requires the use of multiple wireless systems. In the case of user-device interaction, which finds multiple applications such as Ambient ...
Decoupling of multifrequency dipole antenna arrays for microwave imaging applications
(Hindawi Publishing Corporation, 2010)
Artículo / Artikulua,
The mutual coupling between elements of a multifrequency dipole antenna array is experimentally investigated by S-parameter
measurements and planar near-field scanning of the radiated field. A multifrequency array with ...
ASTRA 3B horn antenna design
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
The ASTRA 3B satellite includes 60 Ku-band state-of-the-
art transponders and 4 Ka-band transponders. The
spacecraft have been designed for the distribution of
both direct-to-home (DTH) broadcast services and two way
broadband ...
Electromagnetic response of extraordinary transmission plates inspired on Babinet’s principle
(InTech, 2011)
Capítulo de libro / Liburuen kapitulua,
This chapter is devoted to polarization effects arisen from perforated metallic plates
exhibiting extraordinary transmission (ET). Setting aside the state-of-the-art of perforated
metallic plates, we show that by applying ...
Resolution capabilities of future THz cameras
(Radioengineering Society, 2011)
Artículo / Artikulua,
THz technology for developing imaging systems
has recently aroused great interest, mainly due to the large
number of applications in which these frequencies can be
used: security, vision in hard environments, etc.
In ...
Circuit approach to the minimal configuration of terahertz anomalous extraordinary transmission
(American Institute of Physics, 2011)
Artículo / Artikulua,
In this letter we present an in-depth circuit analysis of anomalous extraordinary transmission ET
through subwavelength slit and hole arrrays loaded by a dielectric slab. We show the key role played
by the thickness of the ...
Design of concentric ring antenna arrays for isoflux radiation in GEO satellites
(Institute of Electronics, Information and Communication Engineers (IEICE), 2011)
Artículo / Artikulua,
The design of concentric rings arrays for isoflux radiation is reported in this paper. This design considers the reduction of the side lobe level and the isoflux radiation requirements for Geostationary Earth Orbit (GEO) ...
Horn antenna lens for multi-beam applications
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
A spherical discrete lens antenna based on the back-toback
combination of two choked-horn antennae arrays
interconnected through smooth waveguides sections
implementing the spherical phasing law, has been
designed, simulated ...
