A Compact 5.8GHz Rectifying Circuit Design and Ezperiments

摘要：

A compact rectenna circuit at 5.8 GHz is presented. A matching inductor and two series diodes are introduced to the rectifying circuit so as to achieve well impedance matching. The circuit simulation and layout electromagnetic (EM) simulation are compared hereby to confirm this design. The layout EM simulation and circuit simulation are close to each other. There is a RF-DC conversion efficiency difference of about 3％-5％ between them. The experiment DC output voltage of the rectifying circuit with this novel design achieves 9.80V at a DC load 2000 Ohm, when the input RF power is at 20 dBm. The highest RF-DC conversion efficiency is 60％. The capacitors used in the rectifying circuit are also studied, and by adjusting their values, the RF-DC conversion efficiency at desired frequencies could be optimized.
