Impedance matching is one of the most important theory for Wireless Power Transfer(WPT). It is to realize complex conjugate condition at both load and source impedances and lumped elements such as inductors and capacitors are used. Lumped elements have ohmic loss so it causes mismatching when they are not considered. In this paper, exact impedance matching circuits are used for different length of dipole and loop antennas and each efficiency is demonstrated.
