Stefania Monni was born in Cagliari, Italy, in 1974. She obtained her MSc. in Electronic Engineering in 1999 at the University of Cagliari, Italy, and her Ph.D. in 2005 at the Technical University of Eindhoven, The Netherlands. Between 1999 and 2000 she has worked as Young Graduate Trainee at ESA ESTEC on SAR interferometry and polarimetry.

Currently, Stefania is a senior scientist at the Radar Technology department of TNO, where she is responsible for the activities of the antenna team, including technical coordination and roadmapping.  As scientist she is involved in in the definition of novel antenna architectures and RF components for microwave instruments, mainly for defence, aerospace and communication applications, and in the investigation of integration aspects between antennas and front-end, particularly for phased array radar. 

Moreover she is responsible for the R&D management of multi-disciplinary research projects encompassing a broad spectrum of technologies for microwave instruments (i.e. antenna, RF front-end and back-end). Customers are (national and/or international) governmental institutions and/or commercial companies, and the work is performed within national/ international teams. In particular, she has managed a four-years program on the development of novel protection architectures for phased array radar front-end, including both antenna and active technologies.  At national level, Stefania has coordinated the efforts for the preparation of the Active Array Antenna roadmap for the Netherlands Space Office and she has been responsible for several studies on the design of a FMCW SAR for a small spaceborne platform.

Her main research interests concern phased array antennas and periodic structures, leaky wave antennas, antenna/front-end integration, digital beam forming and MIMO techniques, mainly for radar application
