Topic: "High Isolation Full Duplex Communication Antennas"

Location: Middle East Technical University, Ankara, Turkey

Abstract: Many technologies are being considered for efficient 5G communication. In-Band Full Duplex (IBFD) is one effective way to increase the spectral efficiency and the throughput of wireless communication systems by transmitting and receiving simultaneously on the same frequency band but the coupling (called Self Interference or SI) of transmit signal to its receiver is one major problem. IBFD operation can be realized successfully by suppressing this coupling or Self Interference (SI). The goal is to achieve high interport isolation for dual port antennas with minimum effect on radiation performance of antennas. In this talk, microstrip patch antennas which deploy different feeding techniques along with Self Interference Cancellation (SIC) circuits to get high interport isolation to enable such antennas for realization of IBFD wireless operation using single/shared antenna architecture will be presented.

Bio: Ibrahim Tekin received the B.S. and M.S. degrees from the Electrical and Electronics Engineering Department, Middle East Technical University, Ankara, Turkey, in 1990 and 1992, respectively, and the Ph.D. degree from The Ohio State University (OSU), Columbus, OH, USA, in 1997. He was with the Electrical Engineering Department, OSU, from 1993 to 1997. From 1997 to 2000,he was a Researcher with the Wireless Technology Laboratory, Bell Laboratories, Lucent Technologies, Murray Hill, NJ, USA. He is currently with the Electronics Engineering Program, Sabanci University, Istanbul, Turkey. He is also involved in various projects, including 77 GHz LNA and antenna design, RFIC design for WLAN systems, and antennas for full duplex systems. He has authored many scientific papers and patents on microwave and antennas area. His current research interests include RF and microwave circuit design and millimeter wave antennas and circuits. Dr. Tekin is a Senior Member of the IEEE Antennas and Propagation Society.
