| Abstract: | A novel microstrip rectifying circuit is proposed in this paper.The rectifying circuit is analyzed and designed with the software ADS 2006A.Simulation results show that the rectifying circuit obtains 81.4% conversion efficiency from microwave to DC power on a load of 320 Ω at 5.80 GHz.The bandwidth of conversion efficiency more than 75% is 300 MHz.Experiment results indicate that the highest voltage of 4.57 V is measured on a load of 298 Ω with conversion efficiency of 68.5%.The rectifying circuit has advantages of compact structure,high conversion efficiency and ease of integration.It can be applied to energy supply for radio frequency identification(RFID) systems and wireless sensors. |
