The exponential growth of using wireless devices in recent years has motivated the exploration of the millimeter-wave (mmWave) frequency spectrum for multi-gigabit wireless communications. Recent advances in antenna technology, radio-frequency complementary metal-oxide semi-conductor (RF CMOS) process and high-speed baseband signal processing algorithms have promised the feasibility of millimeter-wave wireless communications. The multi-gigabit-per-second data rate of millimeter-wave wireless communication systems is leading to applications in many important scenarios, such as wireless personal area networks (WPAN), wireless personal area networks (WLAN), back-haul for cellular systems. The frequency bands include 28 GHz, 38 GHz, 45 GHz, 60 GHz, E-BAND, and even beyond 100 GHz.
The special issue aims to present some major achievements of the research and development in multi-gigabit millimeter-wave wireless communications. It includes four technical contributions from leading researchers in mmWave communications. The first paper entitled “Substrate-Integrated Waveguide-Based Monopulse Slot Antenna Arrays for 60 GHz Applications”, co-authored by ZHU, XUE and LIAO, presents the substrate-integrated waveguide (SIW)-based monopulse slot antenna arrays for the application of 60 GHz monopulse tracking systems. The second paper entitled “Millimeter Wave and THz Propagation Channel Modeling for High-Data Rate Railway Connectivity — Status and Open Challenges” is co-authored by Kürner, GUAN, Molisch, AI, HE, LI, TIAN, DOU and ZHONG. In this paper, the authors provide elementary discussions on bandwidth requirements of high-data rate railway connectivity, and highlight the open challenges in terms of wave propagation, static channel, and dynamic channel.
Co-authored by XU, MENG, MA and YEO, the third paper entitled “State of the Art in Passive Bandpass Filter Solutions for 60-GHz Communications”, reviews the state-of-the-art filter designs for 60-GHz applications. Design methodology, design technology, key performance parameters, similarities and differences, advantages and drawbacks, and future trends are explored and studied. The last (but not least) paper “Low-Power High-Efficiency Multi-Gigabit 60 GHz Transceiver Systems Routing in Vehicular Environments” is co-authored by Byeon and Park. It proposes low-power high-efficiency multi-gigabit 60 GHz transceiver systems for short-range communications. The antenna-in-package module with the transceiver demonstrates mobile-to-display 1080p Full-HD video transmission over a distance of 60 cm.
