Abstract
Optimal operating frequency is studied in this paper to enhance the wireless link efficiency. Frequency effect is analyzed for far-field wireless power transmission. The electrical properties of human muscle is studied to calculate attenuation constant of human tissue and field reflection loss at muscle-to-air interface. The gain of an implantable antenna is estimated after assuming incident plane-wave propagation. Safety considerations are fully considered to establish equivalent isotropic radiated power of external device. The received power is calculated by indoor line-of-sight propagation model. Thus the optimal frequency can be achieved by the maximum received power versus frequency.
