The huge growth and evolution of wireless communications increases the need for the
development of innovative antennas with advanced characteristics. The extensive use of wireless
terminals demands antennas with smaller dimensions and enhanced radiation performance.
There is a strong need for the development of innovative reconfigurable antennas that are able
to change and adapt accordingly some of their operating characteristics. Towards that direction,
a significant research activity is being evolved which is related to the composition or the structure
of innovative materials (chemical compounds, mixtures or metamaterials) with suitably selected
properties which, when incorporated into the development of an antenna, can drastically improve
its characteristics (e.g. antenna miniaturization, tuning frequency and polarization
A key of this course is the synergy between Materials Science and Antenna Technology
aiming at the optimization of the antenna functionality. During the course, the basic principles of
material science will be presented for the structure and the properties of the materials used in
microwave and antennas applications. There will be a number of lectures focusing on the so
called “functional materials” with tunable dielectric and/or magnetic properties. In addition the
theoretical background and the recent evolutions in the area of metamaterials for innovative
antennas will be presented. Hands on simulations and measurements of reconfigurable antenna
prototypes using magneto-dielectric materials are also planned during the course. The course
also includes case studies with characterization measurements of selected materials.
Topics of the course

Material basics (structure and properties of materials)
Functional materials (adjustable εr, silicon based, ferrites with adjustable μr and mixtures)
Synthetic Metamaterials (nanoscale to 3D printed materials)
Magnetodielectric materials and antenna reconfigurability (theoretical analysis and
Case studies (hands on measurements of selected material parameters and antennas with
polarisation and frequency tuning)

Learning outcomes
Attending this course the students will gain experience in the following:

Material and metamaterial characterization measurements and instrumentation
Antenna design, simulation and far-field measurements
Metamaterial design and application to antennas

– The NCSRD is a pleasant green campus with superb conference facilities and ideal climate in
June. It is situated on the foot on Mount Hymettus in a suburb of Athens about 12km to the
north from downtown Athens.
– There is easy interconnection by Metro with the Athens city centre, where there are numerous
hotels overlooking the Acropolis.
– Excursions to the Acropolis and archaeological sites will be organised.
