About the Author
Dr. Albert Sabban earned the BSc degree and MSc degree (magna cum laude) in electrical engineering from Tel Aviv University, Israel in 1976 and 1986, respectively. His MSc thesis was “Spectral Domain Iterative Analysis of Multilayered Microstrip Antennas.” He earned the PhD degree in electrical engineering from Colorado University at Boulder, Colorado, in 1991. His PhD dissertation was “Multiport Network Model for Evaluating Radiation Loss and Coupling among Discontinuities in Microstrip Circuits.” Dr. Sabban’s research interests include microwave and antenna engineering, biomedical engineering, and communication and system engineering.
Dr. Sabban is a senior lecturer, Department of Electrical and Electronic Engineering, Ort Braude Engineering College, Karmiel, Israel. From 1976 to 2007, Dr. Sabban was a senior R&D scientist and project leader in RAFAEL. He successfully passed a system engineering course in RAFAEL. During his work in RAFAEL and other institutes and companies Dr. Sabban gained experience in project management, sales, marketing, and training. He managed and led groups and projects with more than 20 employees.
Dr. Sabban developed radio frequency integrated circuit (RFIC) components on gallium arsenide (GaAs) and silicon substrates. He developed microwave components by employing LTCC technology. In RAFAEL he developed passive and active microwave components such as power amplifiers, low-noise amplifiers, multipliers, voltage-controlled oscillators (VCOs), power dividers filters, and RF heads. Dr. Sabban developed 20 W, 100 W power amplifiers at ultra-high frequencies. He developed a 10 W class C transmitter at L band frequencies with 50% efficiency. He developed a 2 W transmitter at Ka band. He also developed wideband microstrip antenna arrays, dipole antenna arrays, telemetry microstrip antennas, back-fire antennas, reflector antennas, couplers, power dividers, and wideband monopulse comparators. From 1979 to 1984 Dr. Sabban was a teaching assistant in the Electrical Engineering Department in the Technion in Haifa in Israel. From 1984 to 1987 he was the leader of an antenna R&D group in RAFAEL. From 1980 to 1987 he was a leader of several research programs in RAFAEL. In his research programs he developed wideband MM wave microstrip antennas, compact reflector antennas at MM wave frequencies, dielectric rod antennas, and passive microwave components. He also developed an iterative spectral domain analysis of single- and double-layered microstrip antennas using the conjugate gradient algorithm. From August 1987 to February 1991 he was on leave from RAFAEL and joined the University of Colorado at Boulder, where he studied toward his PhD degree. He worked as a research assistant in the microwave and millimeter wave computer-aided design center in the University of Colorado at Boulder. His research topic was “Multiport Network Modeling for Evaluating Radiation Loss and Spurious Coupling among Microstrip Discontinuities in Microstrip Circuits.” Dr. Sabban developed a planar lumped model for evaluating spurious coupling and radiation loss among coupled microstrip discontinuities, a spectral domain algorithm to analyze microstrip lines and coupled microstrip lines, and an iterative spectral domain algorithm to analyze wideband microstrip antennas. He holds a U.S. patent on wideband microstrip antennas. Since March 1991, Dr. Sabban has been working as the leading R&D microwave scientist at RAFAEL, where he developed low-noise amplifiers, power amplifiers, and passive microwave components. From 1991 to August 1993 he worked as a leading R&D engineer in developing RF environmental simulation systems. From August 1993 to August 1994 he worked as a leading R&D engineer in developing a compact low-power consumption integrated RF head for the Inmarsat-M Ground Terminal. From August 1995 to August 1998 he worked as a senior project leader in developing a compact low-power consumption integrated RF head at Ka band for very small aperture terminal (VSAT) applications. From 1988 to July 2000 Dr. Sabban worked as a senior R&D scientist and project leader in developing MMIC RF components and RF heads at Ka band. From July 2000 to 2001 he developed RFIC components on GaAs and silicon substrates. From June 2001 to 2002 he developed microwave components by employing LTCC technology. Since 2002 Dr. Sabban has been working as a senior R&D scientist and project leader in developing MMIC RF modules and RF systems at Ka band. At the beginning of 2005 Dr. Sabban joined the MEMS group in RAFAEL and led and developed projects in the MEMS group.
He published over 60 research papers in journals and conferences and hold a patent in the antenna area.
Dr. Sabban wrote chapters in books on printed antennas. He published in Israel a book on electromagnetic and transmission line theory. His papers are cited in several books and papers.
