A mmWave Low Complexity and Low-Cost Super Wideband Dual-Polarized Aperture Coupled Antenna for 5G Applications
Anja Skrivervik, Abolfazl Azari
Advanced antenna system (AAS) is a viable option for 5G millimeter-wave (mmWave) applications. AAS single element is favored to be dual-polarized, wideband, high gain, and compact in order to be utilized for 5G antenna arrays. In this paper, a low complexi ...
Ieee-Inst Electrical Electronics Engineers Inc2024Low-Cost Multibeam Millimeter-Wave Array Antennas for 5G Mobile Applications
This paper presents a low-cost, compact, multibeam planar antenna system with a wide ±138∘ beam coverage angle at 28 GHz for 5G applications. The proposed microstrip based design includes two branch-line couplers and a Butler matrix with 2×10 and 4×10 seri ...
2022A 28 GHz Beam Steerable Elliptic Microstrip Array Antenna for 5G Applications
This paper discusses the design, fabrication, and measurement of a two-layer, 2×10 elliptic, microstrip series fed antenna array operating at 28 GHz for 5G and mm-wave user equipment. A branch line coupler was used as a feeding network that can generate th ...
2022On the 5G Communications: Fractal-Shaped Antennas for PPDR Applications
In this study, one method of using antennas based on fractals to cover few kinds of public protection and disaster relief (PPDR) communications was presented. Dedicated antenna forms, necessary for antenna design by 5G implementation, were enhanced to suit ...
WILEY-HINDAWI2021Time-Varying Components for Enhancing Wireless Transfer of Power and Information
Romain Christophe Rémy Fleury, Mohammad Sajjad Mirmoosa, Xuchen Wang
Temporal modulation of components of electromagnetic systems provides an exceptional opportunity to engineer the response of those systems in a desired fashion, both in the time and frequency domains. For engineering time-modulated systems, one needs to th ...
2021Ultralow-Profile Circularly Polarized Reflectarray Antenna for CubeSat Intersatellite Links in K-B and
Anja Skrivervik, Miroslav Veljovic
An ultralow-profile circularly polarized (CP) reflectarray (RA) antenna is presented in this article, based on the variable-rotation technique for beam collimation and scanning. Starting from a conventional split-loop element, a new wideband element is des ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021A portable picocell antenna for 5G
Deployable emergency communication systems are a backbone solution for replacing damaged network infrastructures and/or providing high-end services in case of an emergency event. It is important that such systems are up-to-date with the latest mobile netwo ...
EPFL2021Dipole-Fed Rectangular Dielectric Resonator Antennas for Magnetic Resonance Imaging at 7 T: The Impact of Quasi-Transverse Electric Modes on Transmit Field Distribution
Shortened dipole antennas based on rectangular dielectric blocks play an important role in ultrahigh field magnetic resonance imaging (UHF-MRI) radio frequency (RF) coil design. However, the generally assumed direct contact with the subject is difficult to ...
2021Hardware Implementation of Neural Self-Interference Cancellation
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Andreas Toftegaard Kristensen, Yann Kurzo
In-band full-duplex systems can transmit and receive information simultaneously and on the same frequency band. However, due to the strong self-interference caused by the transmitter to its own receiver, the use of non-linear digital self-interference canc ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Stacked patch antenna and hybrid beamforming network for 5G picocell applications
Anja Skrivervik, Danelys Rodríguez Avila
This paper addresses the design of an antenna array for a portable picocell station with omnidirectional coverage. The proposed solution includes a stacked patch antenna as a single radiating element of the antenna array and a hybrid beamforming network. T ...
