WTMWAAC 2022 : Special Issue : Waveguide Transitions for Millimeter-Wave Antenna Arrays Communications

Dear Colleagues,

Communications networks are exponentially increasing the volumes of data traffic. Millimeter-wave (mmWave), THz wireless local area, and cellular networks can support very high download speeds. They have become one of the most interesting techniques to be applied in different areas such as positioning systems, communication between devices, and sensing or imaging transmission, among others. The coverage of mmWave networks has been expanded due to the application of large-scale mmWave antenna arrays. Thanks to the short wavelengths, large antenna arrays can be packed into small dimension supports. We can join more antenna elements in mmWave frequencies than in microwaves facilitating the use of multiple-input multiple-output (MIMO) systems. Antenna arrays can be designed to provide a high-gain link from antennas to end devices. However, physical elements must also be enhanced to support highly directional transmission links, extremely low latencies, and high peak data rates. The application of these antennas in the sensors will allow increasing their applications. For example, it will allow us to create images of physical spaces, through the systematic monitoring of signal signatures received at a wide range of different angles. It will be also possible to detect the presence of some materials or gasses, based on frequency sweep spectroscopy, at frequencies in the THz band.

This Special Issue will reflect current research trends and novel approaches related to the issues of Waveguide Transitions designs and propagation for 5G millimeter-wave applications for mmWave antenna arrays.
