报告摘要

This lecture reviews the fundamental role of impedance matching circuits in wireless communication systems and wireless power transfer systems. A range of matching methods, from lumped-element to distributed circuits, will be presented. Particular attention will be given to practical designs that incorporate element losses in order to ensure both eficiency and reliability.
