A hybrid method on the design of C band microwave rectifiers

Microwave rectifiers have been developed in various forms since the microwave power transmission (MPT) began to attract researchers´ attention. A hybrid simulation method is implemented by the combination of IE3D and ADS simulation to realize a fast and accurate rectifier design in this paper. A 5.8 GHz microstrip rectifier based on HSMS 286 Schottky diode is realized and fabricated based on the proposed method for demonstration. Microstrip structures are light and easy to be integrated into rectennas in a MPT system. The whole circuit is compact with a dimension of 55 mm by 18 mm. The measured MW-to-DC conversion efficiency is 68%, which is obtained at an input microwave power of 16 dBm. The simulated and measured results agree well, which proves the validity of the proposed design method.
