SY] 8 Jul 2026  \nAbstract—Wireless powered communication networks (WPCNs) are a key enabler for sustainable Internet of Things (IoT) systems, yet their practical performance is constrained by inefficient wireless energy transfer, limited spatial adaptability, and fragile uplink connectivity in blockage-prone and dynamic environments. Emerging reconfigurable antenna technologies, including pinching antenna systems (PASSs), fluid antenna systems (FASs), movable antennas (MAs), and reconfigurable intelligent surfaces (RISs), provide new opportunities to overcome these limitations, but have mostly been studied separately. In this article, we propose a unified architecture for fully reconfigurable WPCNs by jointly integrating PASSenabled power beacons, FAS-based IoT devices, MA-assisted base stations, and RIS-aided propagation environments. The proposed framework enables end-to-end reconfigurability across downlink energy transfer, device-side spatial adaptation, base-station reception, and uplink information transmission. We further discuss the integration motivation, system architecture, design and optimization framework, illustrative performance evaluation, implementation tradeoffs, and major practical challenges. This article provides a new perspective for designing next-generation fully reconfigurable WPCNs.  \nI. INTRODUCTION  \nFUTURE Internet of Things (IoT) networks are expected  \nto support massive low-power devices in smart factories, intelligent buildings, environmental monitoring systems, transportation networks, and low-altitude platforms [1] . For these devices, sustainable operation remains a fundamental challenge, since frequent battery replacement or manual recharging is costly and often infeasible in large-scale or hard-to-access deployments. Wireless powered communication networks (WPCNs), where IoT devices harvest radiofrequency (RF) energy and use the harvested energy for uplink information transmission, offer a promising paradigm for energy-sustainable IoT networks [2] .  \nA key limitation of conventional WPCNs lies in their spatially static architecture. In practical deployments, irregular device distributions, blockage, and propagation loss may weaken downlink wireless energy transfer (WET), while uplink wireless information transmission (WIT) is further limited by the harvested energy. Although joint beamforming and resource allocation have been widely studied to improve WPCN  \nBingxin Zhang, Kun Yang are with the State Key Laboratory of Novel Software Technology, Nanjing University, Nanjing, 210008, China, Institute of Intelligent Networks and Communications (NINE), Collaborative Innovation Center of Novel Software Technology and Industrialization, and School of Intelligent Software and Engineering, Nanjing University (Suzhou Campus), Suzhou, 215163, China (email: [bxzhang@nju.edu.cn](bxzhang@nju.edu.cn); [kunyang@nju.edu.cn](kunyang@nju.edu.cn)).  \nYizhe Zhao is with the School of Information and Communication Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China (e-mail: [yzzhao@uestc.edu.cn](yzzhao@uestc.edu.cn)).  \nperformance [3], most existing designs still operate under fixed network geometries, antenna configurations, and propagation environments. Therefore, their adaptability mainly comes from parameter optimization, rather than from reshaping the spatial structure of the energy-information transfer process. Since WET and WIT are tightly coupled, future WPCNs need to move toward a system-level architecture with end-to-end reconfigurability.  \nA new generation of flexible antenna and surface technologies is changing this picture [4] .
