A Dual-Band Reconfigurable Shared-Aperture Antenna Array With Independent Sub-6-GHz and Centimeter-Wave Beam Control
Zhaoyang Ming, Junhui Rao, Jichen Zhang +4
The paper presents a compact planar antenna array that shares a single aperture to operate simultaneously in sub‑6 GHz and centimeter‑wave bands, offering independent 2‑bit beam st…
Multiport Analytical Pixel Electromagnetic Simulator (MAPES) for AI-assisted RFIC and Microwave Circuit Design
Junhui Rao, Yi Liu, Jichen Zhang +6
This paper proposes a novel analytical framework, denoted the Multiport Analytical Pixel Electromagnetic Simulator (MAPES). MAPES enables efficient and accurate prediction of the e…
Pixel-based Reconfigurable Beamforming Networks Emulating Physical Movement in FAS
Jichen Zhang, Junhui Rao, Tianqu Kang +5
The concept of Fluid Antenna Systems (FAS) has emerged as an attractive new system technology for use in sixth-generation (6G) wireless systems. However, most FAS implementations r…
Fluid Antenna System-Enabled Mitigation of Asynchronous Reception in Cell-Free Massive MIMO Systems
Jun Qian, Zan Li, Junhui Rao +2
Practical distributed deployments inherently suffer from asynchronous signal arrivals, which exacerbate multi-user interference and degrade system performance, especially for coher…
A 3D Formulation of the Extended Phaseless Rytov Approximation
Wanqin Ma, Zan Li, Amartansh Dubey +4
The extended Phaseless Rytov Approximation (xPRA) is a recently proposed device-free RF imaging technique that provides high-resolution reconstructions of the imaging region using…
Channel Estimation and Passive Beamforming for Pixel-based Reconfigurable Intelligent Surfaces with Non-Separable State Response
Huayan Guo, Junhui Rao, Alex M. H. Wong +2
Pixel-based reconfigurable intelligent surfaces (RISs) employ a novel design to achieve high reflection gain at a lower hardware cost by eliminating the phase shifters used in trad…
