Miniaturized microstrip antenna array using defected ground structure with enhanced performance

open access: yesEngineering Science and Technology, an International Journal, 2016
The aim of this work is to obtain a miniaturized microstrip patch antenna array using defected ground structure (DGS) for S band at 2.2 GHz. Initially the patch antenna array designed at C band resonates at 5.2 GHz.

5G mmWave patch antenna array with proximity sensing function for detecting user's hand grip on mobile terminals

open access: yesElectronics Letters, 2023
We propose a new concept millimetre‐wave patch antenna that integrates the functions of an antenna and a capacitive proximity sensor to detect the hand grip state for 5G mobile terminals and compensate for the hand effect.

A Gain-Enhanced Patch Antenna With a Periodic Microstrip Rampart Line

open access: yesIEEE Open Journal of Antennas and Propagation, 2022
In this paper, a gain-enhanced patch antenna with a periodic microstrip rampart line is proposed. The periodic microstrip rampart line can modify the effective dielectric constant of the dielectric plate, and help to improve the gain of the traditional ...

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
