Energy Efficiency Optimization of Antenna Technology in 5G/6G Networks

Dear Colleagues,

The transition from 5G to 6G networks is revolutionizing wireless communication by enabling unprecedented data rates, ultra-reliable low-latency communication, and massive connectivity for billions of devices. However, these advancements significantly increase energy consumption, particularly in antenna systems, which constitute one of the most power-demanding components in the network infrastructure. To achieve sustainable, high-performance communication, optimizing energy efficiency in antenna technology has become an essential research priority.

This Special Issue, titled “Energy Efficiency Optimization of Antenna Technology in 5G/6G Networks”, focuses on advancing the understanding and development of energy-efficient antenna systems and architectures for next-generation communication networks. It particularly focuses on innovative design methodologies, hardware solutions, and intelligent optimization techniques that reduce power consumption while maintaining or improving communication performance. Its scope covers theoretical, simulation-based, and experimental studies addressing energy-efficient antennas and related technologies across both access and core network layers. Through this Special Issue, we will create a unified platform where researchers can share the latest findings and propose new directions for greener and more sustainable wireless systems.

While previous studies have explored specific aspects of energy efficiency in communication networks, such as power control, resource allocation, and network planning, comparatively fewer studies have addressed antenna-level challenges and opportunities. This Special Issue will fill this gap by providing a comprehensive perspective that links antenna design, signal processing, and system-level optimization with the common goal of reducing energy consumption in 5G/6G systems. It will, thus, complement the existing literature by emphasizing cross-disciplinary approaches that connect antenna engineering, AI-based optimization, and green communication strategies.

We invite contributions covering, but not limited to, the following topics:

• Energy-efficient antenna design, architectures, and materials;
• Beamforming, MIMO, and massive MIMO energy optimization;
• Reconfigurable Intelligent Surfaces (RIS) for sustainable communication;
• AI- and ML-driven antenna and network energy management;
• Low-power RF front-end and circuit design;
• Energy harvesting, recycling, and wireless power transfer;
• Cross-layer and system-level optimization for green 5G/6G networks.

By collecting original research and review articles on these emerging topics, this Special Issue will serve as a valuable reference for both academic and industrial communities striving to develop energy-conscious solutions for next-generation wireless technologies.
