Design and Applications of Reconfigurable Antenna for 5G Communication

Dear Colleagues,

This Special Issue will explore the latest advancements and innovations in the design, development, and application of reconfigurable antennas for 5G communication systems. The scope encompasses theoretical studies, experimental research, and practical implementations that address the challenges and opportunities presented by 5G technologies. We invite contributions that highlight novel reconfiguration techniques, materials, and methodologies to enhance antenna performance in terms of frequency agility, radiation pattern adaptability, and polarization diversity. This Special Issue will provide a comprehensive overview of state-of-the-art reconfigurable antenna designs, including electronically and mechanically controlled configurations and their integration into 5G networks. Additionally, we welcome papers discussing real-world applications, performance evaluations, and future directions for reconfigurable antennas in 5G and beyond, aiming to bridge the gap between academic research and industry needs. This Special Issue will serve as a valuable resource for researchers, engineers, and practitioners in the fields of wireless communication, antenna design, and 5G technology, fostering collaboration and innovation. Topics of interest include, but are not limited to, the following:

• Basic Principles of Reconfigurable Antennas:

• Definition and key characteristics;
• Differences between reconfigurable antennas and traditional antennas;
• Types of reconfigurable antennas (frequency, polarization, radiation pattern, etc.).

• Materials and Technologies:

• Use of advanced materials (e.g., metamaterials, photonic crystals, liquid crystals, time-varying media);
• Integration of MEMSs (micro-electro-mechanical systems) into reconfigurable antennas;
• Role of smart materials and nanotechnology.

• Design Methodologies:

• Design techniques for frequency reconfigurability;
