System-based Modeling and Characterization of Antennas

Next generation cellular networks and 5G wireless communication systems with complex antenna structures have attracted great attention for their ability to provide high capacity and high data rates. Accurate and effective system models are needed to characterize the performance of such systems. True system models for an antenna as a part of the communication system can significantly improve the overall system  performance evaluation and design studies.

This seminar will explore system modelling of antennas using the singularity expansion method (SEM). The SEM is developed to precisely model UWB antennas and band-notched UWB antennas. The method precisely recognizes the congested band-notches and the operating bands of the tested antennas. The bore-sight impulse responses are utilized to compare the analytical models of single narrow band antennas in the time and frequency domains. Furthermore, to discriminate between the physical complex poles and the nonphysical poles of multi band antennas, a method based on pole energies has been employed. This method decides the model order of the matrix pencil (MP) method based on the extracted pole energies. This improves the performance of the MP method to extract the genuine physical poles and eradicate the nonphysical poles of multi-band antennas with adjacent matched bands.


Majeed A. S. Alkanhal obtained his B.Sc. and M.Sc. degrees in Electrical Engineering from King Saud University, Saudi Arabia, in 1984 and 1986, respectively. He received his Ph.D. degree in Electrical Engineering from Syracuse University, Syracuse, New York in 1994. Dr. Alkanhal is currently a Full Professor in the Electrical Engineering Department at King Saud University. His research interests include RF and microwave/millimeter-wave communications and radar systems, electromagnetic scattering from complex bodies and material objects, antenna design and optimization for communication and radar systems, numerical solutions to electromagnetics and electronic/optical device problems. Professor Alkanhal has served as a consultant, Visiting Scholar, and Referee for several institutes and scientific journals. He has authored books, book chapters, research papers, technical reports, and patents in the fields of his research interests.
