摘要
In this paper, a complete RF to DC wireless power transmission implantable rectenna system is presented. For simplicity, an external half-wave dipole at Industrial, Scientific and Medical bands (ISM 902.8-928 MHz) is selected as an energy emitter from outside human body. An embedded circular dipole antenna receives the energy and then converts it to DC power by a rectifying circuit. The structure of the system is discussed in details. Finally, the rectifying efficiency and the global system's efficiency are examined for different external antenna to human body distances, different embedded depth and various levels of circuit's input power.
