Spatial characterization of personal RF-EMF exposure in public transportation buses
(IEEE, 2019)
Artículo / Artikulua,
New services and applications within vehicular environments employ multiple wireless communication systems,
within a Heterogeneous Network framework. In this context, evaluation of electromagnetic field impact is compulsory, ...
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 ...
Super-wide impedance bandwidth planar antenna for microwave and millimeter-wave applications
(MDPI, 2019)
info:eu-repo/semantics/article,
A feasibility study of a novel configuration for a super-wide impedance planar antenna is presented based on a 2 × 2 microstrip patch antenna (MPA) using CST Microwave Studio. The antenna comprises a symmetrical arrangement ...
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 ...
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 ...
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 ...
New approach to suppress mutual coupling between longitudinal-slotted arrays based on SIW antenna loaded with metal-fences working on VHF/UHF frequency-bands: study, investigation, and principle
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work it is demonstrated that substrate integrated waveguide longitudinal slotted array antenna (SIWLSAA) which is loaded with metal fences exhibits high-isolation across VHF/UHF bands. A reference SIWLSAA used for ...
Design and experimental validation of a LoRaWAN fog computing based architecture for IoT enabled smart campus applications
(MDPI, 2019)
info:eu-repo/semantics/article,
A smart campus is an intelligent infrastructure where smart sensors and actuators collaborate to collect information and interact with the machines, tools, and users of a university campus. As in a smart city, a smart ...
Performance evaluation and interference characterization of wireless sensor networks for complex high-node density scenarios
(MDPI, 2019)
info:eu-repo/semantics/article,
The uncontainable future development of smart regions, as a set of smart cities’ networks assembled, is directly associated with a growing demand of full interactive and connected ubiquitous smart environments. To achieve ...
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 ...
