Dr. Eng. Ahmed Boutejdar was born in Souk El-Arbaa du Gharb, Morocco. He received the Diplom (Licence) in Mathematics, Physics and Chemistry from both universities Technische Hochschule Köthen and from Ibn Tofeil University, Kénitra, Morocco between 1991 and 1995. From 1992 to 1993 Preparatory Year of german language and Preparatory Year of Engineering high School in köthen, Germany. B.Sc. and Diplom-Eng degrees (with highest honors) in Electrical Engineering, Communication, and Microwave Engineering from Otto-von-Guericke university, Magdeburg, Germany in 2002 and 2004 respectively, and the Ph.D. degree, Thesis title: Design, development and optimization of compact microstrip RF filters using "Defected Ground Structure" (DGS) technology (with highest honors) in electrical engineering from the Otto-von-Guericke university, Magdeburg, Germany in 2010. He worked until 2009 on research project entitled "Design, Analysis, and manufacturing of Microstrip Monopole DMS-Antennas and Compact Planar DGS-Filters ", founded by Land Sachsen-Anhalt at the University Magdeburg. From 2010 worked as a research on the project entitled "Design, optimization, CMOS-compatible fabrication and characterization of MEMS tunable planar and coplanar DGS filters". He is currently working in cooperation with the German Research Foundation (DFG) on a new research DFG-project entitled "Capacitive and resistive microelectromechanical switch with bridge structures made of spring steel, in particular for HF applications". His research interests include microwave and filter measurements, design and fabrication of UWB patch antennas, minimisation of compact Defected Ground Structure DGS-filters and antennas using MEMS-technology, design and optimisation of microstrip couplers, Defected Microstrip Structure DMS- compact antennas, reconfigurable planar filters and monopole antennas using varactor devices, measurement techniques and calibration of RF components, electromagnetic modeling (EM) and simulation and RF-circuit simulations.
