Near-Field Wireless Power Transfer Technology for Unmanned Aerial Vehicles: A Systematical Review

Unmanned aerial vehicles (UAVs) technology has seen a significant boost over the past ten years and been widely adopted in entertainment, rescue, intelligent transportation, no-touch delivery, environmental monitoring, other real-world applications. However, ranging limitation due to shortage of battery energy capacity remains major issue hindering further development UAVs. Wireless power transfer (WPT) is new great potentials improving endurance The integration WPT into UAV not only activates recharging UAVs batteries but also enables recharge devices. Moreover, wireless charging allows device be fully enclosed suitable for harsh weather conditions. In this article, we present comprehensive review regard state-of-the-art near-field technologies charging, including characteristics, design issues, as well multiple case studies. A comparative analysis existing presented, associated with key future research discussions
