This study compares rectifier circuits of many kinds that harvest radio frequency energy by utilizing the TL-match approach with those that use the LC-match method. The main purpose of doing the comparison between different types of rectifier circuits under the same frequency of 2.4 GHz is to ease the way for researchers to consider choosing a suitable rectifier circuit from these comparison results that match their application demands. Six different types of rectifier circuits are designed and simulated in this work including: full-wave, half-wave, voltage doubler, Villard charge pump, Graetz charge pump, and Dickson charge pump. These different types of rectifier circuits consist of a standard substrate material with different εr, an HSMS2820 diode, and a 3 kΩ resistance load. Initially, using a single-stage TL-match technique at 2.4 GHz, the rectifiers are constructed on a FR-4 substrate with a thickness of 1.6 mm and a dielectric constant of 4.3. The resistance load was 1 kΩ, the input power range under test was 0 dBm to 30 dBm, and the HSMS2820 diode was employed. The results showed that the Graetz charge pump has the greatest recorded output voltage of about 27 V at 1 kΩ and the best recorded efficiency of 73% at 1 kΩ. Advanced Design System (ADS) is used to design and simulate the rectifier circuits.
