Abstract :
Non-leak energy technology is essential for high power system in microwave power transmission (MPT). MPT mainly consists of a transmitting antenna and a receiving antenna, and we focus on the receiving antenna. Non-leak energy system requires the receiving antenna to receive all the energy which reaches the antenna surface. It is known that the receiving efficiency of an infinite dipole array antenna with reflector becomes 100% analytically under the matching condition by the induced electromotive force (EMF) method. In this paper, the matching condition is discussed by using finite difference time domain (FDTD) method simulation. The radiation impedance is analyzed to satisfy the matching condition. In case that the load impedance is complex conjugate of the radiation impedance, the receiving efficiency reaches 99.9%. In addition, the reflection of the transient state is discussed.
