Advances in Millimeter-Wave Antennas for 5G and Beyond

Dear Colleagues,

High speed and low latency are among the prominent features of 5G mobile communication. Millimeter-wave antennas, as the window of wireless equipment, play an important role in the overall communication system performance. The traditional sub-6G terminal antenna design pays more attention to control the antenna efficiency, polarization, isolation, etc. The current challenge of millimeter-wave band lies in achieving wideband beam scanning in compact handheld devices, integrating antennas and chips, and reducing antenna size and cost while improving antenna efficiency. On the base station side, users are more concerned with the means of achieving efficient and low-cost analog or digital beam control. The development of new car-mounted and on-body terminals in the 5G era will also drive new demands for antennas in bandwidth, efficiency, polarization, beam control, etc. These new requirements drive the development of antenna design towards new design concepts, new materials, and new applications.

In addition, the new demands of 5G millimeter-wave antennas in beamforming and calibration, system RF testing, etc., pose new challenges to traditional measurement techniques, and the question how to obtain test and calibration results efficiently and accurately is driving new advances in the testing field.

This Special Issue aims to include papers on, but not limited to, new mmWave antenna design concepts for 5G. Authors are encouraged and welcomed to submit any new concepts or ideas about millimeter-wave antennas.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following topics:

• Millimeter-wave antenna;
• Phased arrays;
• Reflectarrays and transmitarrays;
• Smart antenna;
• Handset antenna;
• Base-station antenna;
• Metasurface antenna;
• Reconfigurable devices;
• Biomedical antenna;
• 5G, 6G and antenna wave propagation;
• Antenna measurement;
• Over-the-air measurement.

We look forward to receiving your contributions.
