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 ...
Analysis of the combinatory effect of uniaxial electrical and magnetic anisotropy on the input impedance and mutual coupling of a printed dipole antenna
(IEEE, 2021)
Artículo / Artikulua,
The main objective of this work is to investigate the combinatory effects of both uniaxial magnetic and electrical anisotropies on the input impedance, resonant length and the mutual coupling between two dipoles printed ...
Future smartphone: MIMO antenna system for 5G mobile terminals
(IEEE, 2021)
Artículo / Artikulua,
In this article, an inverted L-shaped monopole eight elements Multiple Input Multiple Output (MIMO) antenna system is presented. The multi-antenna system is designed on a low cost 0.8 mm thick FR4 substrate having dimensions ...
A comprehensive survey on 'circular polarized antennas' for existing and emerging wireless communication technologies
(IOP Publishing, 2022)
