Part Time / September  26-Mondey Morning

Millimeter-wave (mmW) systems offers ultra-broad information bandwidth and ultra-high spatial and
temporal resolutions, which are vital for a number of emerging applications such as 5G, next generation
mobile satellite communications, high precision automotive sensor/radars, and imagers. With the high cost
and complexity of power generation and low-noise amplification in millimeter-waves, active intelligent
antenna system with a fast and high-performance radiation beam-forming capability becomes a key enabler
of the aforementioned applications.
Intelligent antenna systems are reconfigurable conformal and active radiating systems with appropriate
built-in intelligence close to the radiating aperture. Aggressive feature-size scaling has enabled a number of
commercial foundries to provide the system developers with the low-cost millimeter-wave active devices
and system-on-chip (SOC) technologies with impressive level of sophistication and functionalities. The
new advances in millimeter-wave packaging methods, in conjunction with the advances in low-cost
millimeter-wave integrated circuit technologies (MMIC) have paved the way for affordable integrated
intelligent antenna system technologies for a wide range of emerging applications.
The workshop starts with a general review of requirements for a number of emerging applications including
5G mmW networks, next generation mmW satellite communication, and mmW sensing. A major focus will
be placed on high-performance mobile applications and reconfigurable antenna system configurations.
Main challenges and fundamental limitations in terms of practical constraints of intelligent antenna systems
will be described.
General analysis/simulation and optimization strategies for designing conformal active antenna systems
with beam-forming capability will be presented. It will be shown that modular (hardware/software)
architecture and an integrated calibration and system identification/characterization system are essential to
realization of a low-cost/complexity and a high-performance intelligent antenna system. Practical examples
related to a number of recent projects in the University of Waterloo Centre for Intelligent Antenna and
Radio Systems (CIARS) will be used to illustrate the presented concepts.
