Optical-microwave sensor for real-time measurement of water contamination in oil derivatives
(Elsevier, 2023)
Artículo / Artikulua,
This paper presents a novel microwave sensor using optical activation for measuring in real-time the water
contamination in crude oil or its derivatives. The sensor is constructed from an end-coupled microstrip resonator
that ...
Metamaterial inspired electromagnetic bandgap filter for ultra-wide stopband screening devices of electromagnetic interference
(Springer, 2023)
Artículo / Artikulua,
Presented here is a reactively loaded microstrip transmission line that exhibit an ultra-wide
bandgap. The reactive loading is periodically distributed along the transmission line, which is
electromagnetically coupled. ...
Design of high gain base station antenna array for mm-wave cellular communication systems
(Springer Nature, 2023)
Artículo / Artikulua,
Millimeter wave (mm-Wave) wireless communication systems require high gain antennas to overcome path loss effects and thereby enhance system coverage. This paper presents the design and analysis of an antenna array for ...
Review on unmanned aerial vehicle assisted sensor node localization in wireless networks: soft computing approaches
(IEEE, 2022)
Artículo / Artikulua,
Node positioning or localization is a critical requisite for numerous position-based applications of wireless sensor network (WSN). Localization using the unmanned aerial vehicle (UAV) is preferred over localization using ...
Impedance bandwidth improvement of a planar antenna based on metamaterial-inspired T-matching network
(Institute of Electrical and Electronics Engineers Inc., 2021)
Artículo / Artikulua,
In this paper a metamaterial-inspired T-matching network is directly imbedded inside the feedline of a microstrip antenna to realize optimum power transfer between the front-end of an RF Wireless transceiver and the antenna. ...
Optimum power transfer in RF front end systems using adaptive impedance matching technique
(Nature Research, 2021)
Artículo / Artikulua,
Matching the antenna’s impedance to the RF-front-end of a wireless communications system is challenging as the impedance varies with its surround environment. Autonomously matching the antenna to the RF-front-end is therefore ...
A comprehensive survey on 'circular polarized antennas' for existing and emerging wireless communication technologies
(IOP Publishing, 2022)
info:eu-repo/semantics/article,
Circular polarized (CP) antennas are well suited for long-distance transmission attainment. In order to be adaptable for beyond 5G communication, a detailed and systematic investigation of their important conventional ...
Broadband 3-D shared aperture high isolation nine-element antenna array for on-demand millimeter-wave 5G applications
(Elsevier, 2022)
Artículo / Artikulua,
The paper presents the results of a novel 3-D shared aperture 3 × 3 matrix antenna-array for 26
GHz band 5 G wireless networks. Radiation elements constituting the array are hexagonal-shaped
patches that are elevated ...
Electronically reconfigurable and conformal triband antenna for wireless communications systems and portable devices
(Public Library of Science, 2022)
Artículo / Artikulua,
This paper presents the design of a triband antenna that can be electronically configured to
operate at different frequencies. The proposed antenna is design to operate at sub-6GHz
bands at 2.45 GHz (ISM, Wi-Fi, and ...
Novel concentric hexagonal-shaped RFID tag antenna with T-shaped stub matching
(IEEE, 2021)
info:eu-repo/semantics/article,
This paper presents a unique concentric hexagonal-shaped ring antenna for radio frequency identification (RFID) tags. The rings are excited with a common microstrip feedline. The radiation characteristics of the antenna ...
