Metasurface-Based Array Antennas for Communication Systems

Dear Colleagues,

The increasing demands for higher data rates, reduced latency, and improved spectral efficiency in wireless communication systems have accelerated the need for innovative antenna technologies. Among these, metasurface-based array antennas have gained significant attention due to their ability to manipulate electromagnetic waves with high precision. Metasurfaces can manipulate wavefronts, enabling functions such as beam steering, multibeam generation, polarization control, electromagnetic transparency, reflectarrays, absorption, low-RCS antennas, low sidelobe levels (SLLs), and intelligent reconfigurable surfaces (IRS) for wireless communication systems.

This Special Issue focuses on the design, analysis, and application of metasurface-based array antennas in modern wireless communication systems, particularly in the context of 5G and beyond. By integrating metasurfaces into array antennas, we demonstrate improved beamforming capabilities, enhanced directivity, reduced undesired mutual coupling, and increased bandwidth efficiency. The unique properties of metasurfaces also allow for antenna miniaturization, making them ideal for space-constrained applications and for arrays with different frequency bands. This Special Issue further aims to bring together the role of metasurface-based arrays in multi-input multi-output (MIMO) and phased array systems, highlighting their potential for improving signal-to-noise ratio (SNR), spatial multiplexing while reducing interference, and electromagnetic transparency.

Objective:

The primary goal of this Special Issue is to present state-of-the-art research on metasurface-based antennas and arrays emphasizing their role in enhancing wireless communication systems. This includes topics related to the design, analysis, simulation, and practical implementations of antenna systems, as well as their integration into modern communication networks.

Key Topics:

Original research articles as well as review papers are welcome in this Special Issue. Research areas may include (but are not limited to) the following:

• Ultra-wideband (UWB), millimeter-wave (mmWave), and terahertz antenna arrays;
• Electrically small antennas and miniaturization techniques;
• High-gain, beamforming, and beam-steering antennas;
• Reconfigurable antennas (pattern, frequency, polarization, beam, etc.);
• Reconfigurable intelligent surfaces (RISs);
• Dual-polarized antenna arrays;
• Printing technologies for antenna arrays;
• Reduction of the undesired mutual coupling in antenna arrays;
• Metasurfaces: theory and applications;
• Reduction of crossband interference in multiband antenna arrays;
