Photonic controlled metasurface for intelligent antenna beam steering applications including 6G mobile communication systems
(Elsevier, 2023)
Artículo / Artikulua,
This paper presents a novel metasurface antenna whose radiation characteristics can be remotely controlled by
optical means using PIN photodiodes. The proposed reconfigurable antenna is implemented using a single
radiating ...
Virtual antenna array for reduced energy per bit transmission at Sub-5 GHz mobile wireless communication systems
(Elsevier, 2023)
Artículo / Artikulua,
This paper presents an innovative technique to synthesize a virtual antenna array (VAA) that consumes less energy than conventional antenna arrays that are used in mobile communications systems. We have shown that for a ...
High gain/bandwidth off-chip antenna loaded with metamaterial unit-cell impedance matching circuit for sub-terahertz near-field electronic systems
(Springer, 2022)
Artículo / Artikulua,
An innovative of-chip antenna (OCA) is presented that exhibits high gain and efciency performance
at the terahertz (THz) band and has a wide operational bandwidth. The proposed OCA is implemented
on stacked silicon layers ...
Analysis of low power wide area network wireless technologies in smart agriculture for large-scale farm monitoring and tractor communications
(Elsevier, 2022)
Artículo / Artikulua,
In this paper, the assessment of multiple scenario cases for large-scale farm monitoring using Low-Power Wide-Area Network (LPWAN) based near-ground sensor nodes with the interaction of both tractors and farmers are ...
A 3-D indoor analysis of path loss modeling using kriging techniques
(IEEE, 2022)
Artículo / Artikulua,
This study proposes a novel measurement-based method to predict and model three-dimensional (3-D) path loss in indoor scenarios, which first regresses 28 GHz measurements via median path loss modeling and then includes ...
Electromagnetic assessment of UHF-RFID devices in healthcare environment
(MDPI, 2022)
Artículo / Artikulua,
In this work, the evaluation of electromagnetic effect of Ultra High Frequency Radio Frequency Identification (UHF-RFID) passive tags used in the healthcare environment is presented. In order to evaluate exposure levels ...
An enhanced approach to virtually increase quasi-stationarity regions within geometric channel models for vehicular communications
(IEEE, 2023)
Artículo / Artikulua,
Vehicular communication channels are intrinsically
non-stationary, as they present high mobility and abundant dynamic
scatterers. Quasi-stationary regions can assess the degree
of non-stationarity within a determined ...
Spatial V2X traffic density channel characterization for urban environments
