Implementation of radiating elements for radiofrequency front-ends by screen-printing techniques for Internet of Things applications
(MDPI, 2019)
info:eu-repo/semantics/article,
The advent of the Internet of Things (IoT) has led to embedding wireless transceivers into a wide range of devices, in order to implement context-aware scenarios, in which a massive amount of transceivers is foreseen. In ...
Effects of the body wearable sensor position on the UWB localization accuracy
(MDPI, 2019)
info:eu-repo/semantics/article,
Over the years, several Ultrawideband (UWB) localization systems have been proposed and evaluated for accurate estimation of the position for pedestrians. However, most of them are evaluated for a particular wearable sensor ...
Hybrid computational techniques: electromagnetic propagation analysis in complex indoor environments
(IEEE, 2019)
info:eu-repo/semantics/article,
In this article, we compare deterministic methodologies for characterizing channel behavior in heterogeneous and composite scenarios. These techniques include one that combines a 3D ray launching (RL) approach based on ...
Impact of body wearable sensor positions on UWB ranging
(IEEE, 2019)
info:eu-repo/semantics/article,
In recent years, Ultrawideband (UWB) has become a very popular technology for time of flight (TOF) based localization and tracking applications but its human body interactions have not been studied yet extensively. Most ...
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 ...
A radio channel model for D2D communications blocked by single trees in forest environments
(MDPI, 2019)
info:eu-repo/semantics/article,
In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ...
Surface wave reduction in antenna arrays using metasurface inclusion for MIMO and SAR systems
(Advancing Earth and Space Science, 2019)
info:eu-repo/semantics/article,
An effective method is presented for suppressing mutual coupling between adjacent radiating elements which is based on metasurface isolation for multiple-input multiple-output (MIMO) and synthetic aperture radar (SAR) ...
A new study to suppress mutual-coupling between waveguide slot array antennas based on metasurface bulkhead for MIMO systems
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper, a new method is proposed to reduce mutual coupling between waveguide slot array (WSA) antennas based on metasurface technology. This is achieved by placing a metasurface bulkhead between the two WSA antennas. ...
High-performance 50μm silicon-based on-chip antenna with high port-to-port isolation implemented by metamaterial and SIW concepts for THz integrated systems
(IEEE, 2019)
info:eu-repo/semantics/article,
A novel 50μm Silicon-based on-chip antenna is presented that combines metamaterial (MTM) and substrate integrated waveguide (SIW) technologies for integration in THz circuits operating from 0.28 to 0.30 THz. The antenna ...
Meta-surface wall suppression of mutual coupling between microstrip patch antenna arrays for THz-band applications
(EMW Publishing, 2018)
info:eu-repo/semantics/article,
This paper presents a novel 2D meta-surface wall to increase the isolation between microstrip patch radiators in an antenna array that is operating in the teraherz (THz) band of 139-141 GHz for applications including ...
