Mr. Xavier Artiga obtained his “Ingeniero Superior” degree (equivalent to M.Sc.) in Telecommunications Engineering at Universitat Politècnica de Catalunya (UPC) in July 2006. He joined CTTC in September 2007 as a Researcher. Prior this, he worked as a Management Analyst at Bearingpoint Consultants (November 2006- August 2007) and in 2002, he did an undergraduate training at Nokia Spain.

At CTTC, he has played the role of assisting the coordination of research consortiums in European and National funded projects such as H2020-SANSA and ELISA (TEC2014-59255-C3-1-R); as well of technical contributor in the field of antenna design in these and other European and National funded projects like FP7-BuNGee or TERESA (TEC2017-90093-C3-1-R). Besides, he has also technically contributed to several industrial contracts, including ESA projects like SATNEX IV (Work Item 4.5), and managed some of them like POLAR series projects. He was also largely involved in the in the development of the CTTC strategic ultrawideband Testbed ULAND. In the last years, he has developed strong skills for European proposal coordination and elaboration which translated in the co-coordination of at least one proposal each of the last 3 years. He is co-author of more than 20 scientific publications.

His current research interests include reflectarray and metasurface antennas, reconfigurable antennas and multiantenna and Massive MIMO systems for terrestrial and satellite systems. He is a regular reviewer of IEEE Transactions on Antennas and Propagation and IEEE Antennas and Wireless Propagation Letters.
