Antennas are wave mode changers, that are classically described by a set of antenna parameters such as input impedance, gain, directivity, antenna factor and radiation diagram. Due to progressing complexity and integration of transmission systems, the exact knowledge of these parameters is getting more and more important. For the measurement of quantities conforming to standards, different measurement setups in absorber chambers and on open-area test sites exist. With progressing computational capabilities, computationally intensive methods based on near-field-tofar-field transformation gain importance. Flying measurement platforms based on autarkic multicopters are used for the characterization of large stationary antenna systems. The talk shows some new developments.
Electromagnetic field theory is probably not the most favorite topic for many engineers, but it is crucial for understanding EMC. Many times, teaching of electromagnetic fields includes a lot of heavy mathematics obscuring the actual physics of electromagnetic fields. In this presentation, I use 3D electromagnetic field simulations to visualize the behavior of fields and how it results in effects that are important for EMC. After a short introduction to the calculation methods, I will discuss concepts that we use daily like voltage, current, power transfer and shielding in terms of electromagnetic fields.
