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 ...
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 ...

(IEEE, 2020)
Artículo / Artikulua,
Nowadays synthetic aperture radar (SAR) and multiple-input-multiple-output (MIMO)
antenna systems with the capability to radiate waves in more than one pattern and polarization are playing a
key role in modern telecommunication ...
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 ...
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. ...

Interaction between closely packed array antenna elements using meta-surface for applications such as MIMO systems and synthetic aperture radars
(Wiley, 2018)
info:eu-repo/semantics/article,
The paper presents a technique to enhance the isolation between adjacent radiating elements that is common in densely packed antenna arrays. Such antennas provide frequency beam-scanning capability needed in multiple-input ...
Antenna mutual coupling suppression over wideband using embedded periphery slot for antenna arrays
(MDPI, 2018)
info:eu-repo/semantics/article,
This paper presents a new approach to suppress interference between neighbouring radiating elements resulting from surface wave currents. The proposed technique will enable the realization of low-profile implementation of ...
A new waveguide slot array antenna with high isolation and high antenna bandwidth operation on Ku- and K- Bands for radar and MIMO systems
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper a novel technique is proposed to reduce the mutual coupling between the radiating elements of a waveguide slot array antenna. This is achieved by inserting slots between the waveguide oval shaped slots. The ...
