Design of broadband RF-DC converter

Abstract

Almost all of the wireless devices are supplied by chemical batteries. These batteries have a number of disadvantages. In this study, a broadband RF energy harvester was designed to providing the use of wireless devices without batteries or increasing battery life. The system is designed to work between 500 MHz and 900 MHz. Thus, the proposed system can be obtained electrical energy from both DTV and GSM signals at the same time. The system efficiency which is mentioned above frequencies ranges is close to 80% for 0 dBm input power level.
