goals

The students have acquired in-depth knowledge of metrological characterization of transmit and receive circuits as well as various antenna systems. They have learned to use state-of-the-art microwave measurement devices and three-dimensional field simulation software.

content

Both receiving and transmitting units of a communication system are composed of different microwave components, e.g. low-noise preamplifiers, mixers, power amplifiers and filters. To ensure reliable operation of the entire system, different requirements are placed on each of these components depending on the target application. Accordingly, the first part of the practical course covers the characterization of the individual components in a receiving and transmitting unit using a 'testbed'. For this purpose, the students are introduced to the practical use of spectrum and network analysis. The focus of the second part is the investigation of antenna properties. For the wireless transmission of electromagnetic waves, antennas are required to send and receive the respective signal. While the transmitting antenna ensures the radiation of the generated signal, the receiving antenna transforms the signal back into a voltage at its base point. For the development of such antenna systems numerical field simulators are used, which allow for the calculation of antenna characteristics such as antenna gain, directivity and return loss based on three-dimensional models. To acquire a deeper understanding of this development process, the students independently carry out field simulations of an antenna system and the properties of different antenna systems are characterized metrologically.
