Research involves

Developing design techniques that improve the sensitivity of receivers and radiometers as part of antenna arrays that operate at the radio and terahertz frequencies.

Research relevance

This research will lead to the development of highly sensitive receiver systems for use in applications ranging from scientific instruments to security systems.

Antenna Arrays for Broadband Data Communications

Broadband data communications are everywhere these days, and are increasingly mobile. The explosive growth in broadband data communications has been accommodated mainly by sharing the available frequency spectrum, using advanced signal processing techniques, and allocating more spectrum space to communication systems.

Since, there are limitations to these approaches, the next challenge is to make more efficient use of antenna arrays for broadband data communications. Antenna arrays, which can adjust the orientation of beams and make it possible for more than one beam to form, have been around since the early 20th century, and are widely used in satellite communications and military and aerospace applications.

Dr. Leonid Belostotski, Canada Research Chair in High-Sensitivity Radiometers and Receivers, is concentrating on the development and implementation of high-sensitivity radio frequency receiver and radiometer antenna arrays that operate in the radio frequency and terahertz frequencies for use in radio astronomy, telecommunications and imaging.

Belostotski’s research will lead to technologies that lower antenna arrays's cost and power consumption and increase their performance to support further growth in broadband data communications.
