Dielectric-Waveguide Integrated Technologies for Emerging Millimeter-wave/Terahertz Systems: Millimeter-waves (mmW) to terahertz (THz) spectra have opened up new possibilities for a wide variety of applications ranging from ultra-broad-band communication systems to mobile satellite communication and ultra-high resolution automotive radars, security imagers, and biomedical sensors. Advances in nano-scale semi-conductor technologies (CMOS and Si-Ge) and high precision wafer scale integration have enabled on-chip highly advanced system architectures and paved the way for commercial exploitation of the unique prperties of these ranges of frequencies. A major challenge in mass market implementation of mmW/THz system concepts is lack of lowcost/ complexity high-performance passive technologies and a suitable integration platform (wave-guides, filter/resonators, sensor, feed circuit, antenna, etc.). Multilayer planar lines become quite lossy at mmW. Substrate Integrated Waveguides (SIW) offer a lower insertion-loss at lower mmW (less than 100 GHz). Above 150 GHz, rectangular metallic waveguide is the only option. Such waveguides become quite costly and extremely difficult to incorporate into full system integration schemes, particularly as we approach higher mmW band and THz bands. Over the last few years, millimeter-wave/THz dielectric waveguides, made of high resistivity silicon, quartz, or certain polymers, have been proposed as a highly promising approach to realize potentially lowloss transmission lines and building blocks for more complex devices at mmW to THz range of frequencies. The speaker’s research group have been developing a high resistivity silicon (HRS) technology platform for mmW/THz integrated systems over the recent years. In this keynote, the state-of-the-art in mmW/THz system integration technologies will be reviewed. Challenges and opportunities will be described. Recent advances in mmW/THz integrated system technologies at the University of Waterloo Centre of Intelligent Antenna and Radio Systems (CIARS) will be presented.
