Electric and magnetic fields have been known to be a manifestation of the same physical phenomenon for almost two hundred years, but some aspects of electromagnetism are not in balance in nature around us. We are faced with restrictions due to lack of real magnetic charges, currents, and conductors. However, it has turned out that virtual magnetic currents and conductors and magnetic materials can be engineered and used in a variety of applications, antennas being one amongst them. This doctoral thesis focuses on magnetic materials and artificially created magnetic responses in antenna applications. The thesis is divided into three parts concerning antennas in which the magnetic part of Maxwell's equations plays a key role. The common goal...
