| The seminar will focus on
development of essentially new terminal and base station antennas:
small-size antennas, base station antennas and smart antenna technology.
Majority of the investigated planar or conformal small antennas are for
operation with several systems. There is an undoubted demand for
considerable improvement in the antenna technology of base stations. In our
study we use two types of composite technology in base station antennas. The
technology allows development of planar and conformal - mostly cylindrical -
antenna arrays. For the reason of technological compatibility, we use the
microstrip technology in the other microwave parts of the beamforming
networks. The most promising results were those obtained for the multilayer
directional couplers. We developed a generic concept of a conformal terminal
antenna for Inmarsat system. The major objective of our research on
smart antennas was development of operational scenarios applicable to base
station antennas. Following development of operational scenarios, generic
concepts of smart antennas were proposed. A part of the talk will describe
modern measuring methodology developed under Prof. Kabacik supervision.
Research on the interaction between terminals and operators has concentrated
on the actual properties of terminal antennas under the proximity of the
operator. We developed, entirely on our own, a near-field measuring system
which utilizes the bi-polar technique. Antenna arrays with a fixed and an
electronically scanned beam were tested. |
| Pawel Kabacik was
born in Wroclaw, Poland, on January 1, 1963. He received the M.Sc.
(telecommunications) and Ph.D. (electrical engineering) degrees, both from
the Wroclaw University of Technology, Poland. From 1986 to 1988, he studied
computer science at the Wroclaw University of Technology. In January 1987,
he joined the Institute of Telecommunications and Acoustics, Wroclaw
University of Technology, and, in 1996, he became an Assistant Professor
there. His research interests include antenna arrays, phased arrays,
near-field antenna measurements, digital beam-forming techniques and smart
antennas. Dr. Kabacik was a member of the European COST 245 Project and COST
260 Project. He supervised a research team working on conformal arrays
within COST260 project. In 1993, he received the Award for Young Scientists
at the VIIth National URSI Symposium, Poland. In 2000, he received the IEEE
H. A. Wheeler Award Honorable Mention. He was a Principal Investigator
of numerous industry founded projects and grants of Polish Research Council.
His name is listed in several editions of Marquis’s Who’s Who in
Science and Engineering and in Marquis’s Who’s Who in the World. |
