Compact EBG-Backed Planar Monopole for BAN Wearable Applications
Muhammad Ali Babar Abbasi,Symeon Nikolaou,Marco A. Antoniades,Marija Nikolic Stevanovic,Photos Vryonides +4 more
TL;DR: In this paper, a planar monopole with a 2 × 1 array of electromagnetic bandgap (EBG) structures is proposed for wearable applications, where the shape of the unit cell and the gap between the ground and the EBG layer are adjusted so that the antenna operates at 2.45 GHz.
Journal ArticleDOI
Design and Development of a Compact UWB Monopole Antenna With Easily-Controllable Return Loss
TL;DR: This communication presents a novel cactus-shaped ultrawideband (UWB) monopole antenna fabricated on liquid crystal polymer (LCP) that presents very consistent omnidirectional patterns throughout the UWB frequency range.
Journal ArticleDOI
Antenna Selection and Designing for THz Applications: Suitability and Performance Evaluation: A Survey
TL;DR: This paper serves an introductory guideline to address the challenges and opportunities, while designing the antenna for THz communications requiring innovative solutions.
Journal ArticleDOI
Reconfigurable Bandwidth Bandpass Filter With Enhanced Out-of-Band Rejection Using $\pi $ -Section-Loaded Ring Resonator
Salman Arain,Photos Vryonides,Muhammad Ali Babar Abbasi,Abdul Quddious,Marco A. Antoniades,Symeon Nikolaou +5 more
TL;DR: A novel ring resonator bandpass filter with reconfigurable bandwidth with central frequency at 2.4 GHz is demonstrated and the design approach of implementing $\pi $ -section stubs connected to the ring to obtain the bandwidth reconfigurability is explained.
Journal ArticleDOI
Constant- ${\epsilon}_{r}$ Lens Beamformer for Low-Complexity Millimeter-Wave Hybrid MIMO
TL;DR: In this article, a beamforming solution based on constant dielectric material (€ r) with antenna feeds is presented for multibeam operation, and a characterization at 28 GHz is performed wherein an uplink signal-to-noise ratio of user terminals is evaluated with the zero-forcing (ZF) baseband signal processing.
