Università Roma Tre

This course gives theoretical and experimental basis for the characterization of microwave and radiofrequency circuits and antennas. The first part of the course will be devoted to measurements in guided structures, in particular the student will be introduced to measurement of frequency, wavelength, attenuation, swr, and impedance. The scattering parameters of microwave components will also be measured. The second part of the course will be devoted to the characterization of different types of antennas: measurements of gain, directivity, radiation pattern and polarization will be performed, by using horn antennas, parabolic reflectors, arrays of slot and of microstrip antennas, loop antennas, yagi-uda and log-periodic antennas. In a final part of the course, environmental electromagnetic fields will be measured, due to electromagnetic pollution, by employing both wide-band and selective techniques. At the end of the course the student will be able to plan and perform experimental activities, in the electromagnetic fields area, by adopting the most appropriate equipment and components.
