Interaction between closely packed array antenna elements using meta-surface for applications such as MIMO systems and synthetic aperture radars
(Wiley, 2018)
info:eu-repo/semantics/article,
The paper presents a technique to enhance the isolation between adjacent radiating elements that is common in densely packed antenna arrays. Such antennas provide frequency beam-scanning capability needed in multiple-input ...
Antenna mutual coupling suppression over wideband using embedded periphery slot for antenna arrays
(MDPI, 2018)
info:eu-repo/semantics/article,
This paper presents a new approach to suppress interference between neighbouring radiating elements resulting from surface wave currents. The proposed technique will enable the realization of low-profile implementation of ...
Optimization and design of wireless systems for the implementation of context aware scenarios in railway passenger vehicles
(IEEE, 2017)
Artículo / Artikulua,
In this paper, intra-wagon wireless communication
performance is analyzed, in order to account for inherent
scenario complexity in the deployment phase of wireless systems
toward the implementation of a context-aware ...
A hybrid ray launching-diffusion equation approach for propagation prediction in complex indoor environments
(IEEE, 2017)
Artículo / Artikulua,
A novel and efficient deterministic approach to
model radio wave propagation channels in complex indoor
environments improving prediction accuracy is proposed. This
technique combines a 3-D Ray Launching algorithm based ...
Study on isolation improvement between closely-packed patch antenna arrays based on fractal metamaterial electromagnetic bandgap structures
(Institution of Engineering and Technology, 2018)
info:eu-repo/semantics/article,
A decoupling metamaterial (MTM) configuration based on fractal electromagnetic-bandgap (EMBG) structure is shown to significantly enhance isolation between transmitting and receiving antenna elements in a closely-packed ...
Integration of autonomous wireless sensor networks in academic school gardens
(MDPI, 2018)
info:eu-repo/semantics/article,
In this work, the combination of capabilities provided by Wireless Sensor Networks (WSN) with parameter observation in a school garden is employed in order to provide an environment for school garden integration as a ...
FDTD and empirical exploration of human body and UWB radiation interaction on TOF ranging
(IEEE, 2019)
Artículo / Artikulua,
In time-of-flight (TOF)-based human ranging systems, target sensors are often mounted on or close to the human
body, which may raise non-line-of-sight (NLOS) cases and lead
to significant ranging errors depending on the ...
Towards a traceability system based on RFID technology to check the content of pallets within electronic devices supply chain
(Hindawi, 2013)
info:eu-repo/semantics/article,
In the last few years there has been a growing interest in smart solutions capable of dealing with the traceability of products and
materials to improve logistical processes. Most of the existing solutions have been ...
Performance analysis of ZigBee wireless networks for AAL through hybrid ray launching and collaborative filtering
(Hindawi, 2016)
info:eu-repo/semantics/article,
This paper presents a novel hybrid simulation method based on the combination of an in-house developed 3D ray launching
algorithm and a collaborative filtering (CF) technique, which will be used to analyze the performance ...
Implementation and operational analysis of an interactive intensive care unit within a smart health context
(MDPI, 2018)
info:eu-repo/semantics/article,
In the context of hospital management and operation, Intensive Care Units (ICU) are
one of the most challenging in terms of time responsiveness and criticality, in which adequate
resource management and signal processing ...
