📄 Abstract
The rapid expansion of the Internet of Things (IoT) has intensified the demand for efficient, reliable, and sustainable wireless communication systems. Electromagnetic (EM) waves serve as the fundamental medium enabling connectivity among billions of IoT devices, ranging from smart home sensors to industrial automation systems. This study explores the intersection of IoT and EM wave technologies, focusing on spectrum utilization, antenna design, and energy harvesting. Key innovations include the application of orbital angular momentum (OAM) in EM waves to enhance spectral efficiency, the development of miniaturized and high-performance antennas tailored for IoT environments, and the integration of RF energy harvesting to support self-powered devices. Challenges such as spectrum scarcity, interference management, and hardware miniaturization are critically examined. The research highlights future directions, including AI-driven spectrum allocation, millimeter-wave IoT for ultra-low latency communication, and hybrid energy models combining RF, solar, and kinetic sources. By synthesizing current advancements and emerging trends, this work underscores the pivotal role of EM wave innovations in shaping sustainable and scalable IoT ecosystems, particularly in the context of next-generation 6G networks and smart city infrastructures.
