Guest Editorial: Special Cluster on Antenna Considerations for Future Millimeter-Wave and Terahertz Wireless Systems

The thirteen papers in this special section focus on antenna considerations for future millimeter-wave and terahertz wireless sytems. Recent developments in data-intensive applications and emergence of Internet-of-Things (IoT) have exponentially increased the wireless data traffic. IoT also requires fusion of multiple sensors and wireless devices operating in real time. These papers present state-of-the-art research on a wide range of antenna technologies, analysis techniques, and application scenarios in millimeter-wave and terahertz regimes. The 13 letters of this cluster are categorized in five groups based on the type of the antenna/broader focus.
