Abstract :
This paper introduces an improved detector topology which is used to design the rectifier that is a part of a rectenna, operating in the S-band. Our proposition adds a third diode into the conventional half bridge detector, leading to improve the output DC voltage and to reduce the harmonics power level. Then, a rectifying circuit is built using two approaches. The first rectifier is based on a HSMS2822 doubler with a HSMS2820 diode. While the second rectifier uses a HSMS282P quad. We have achieved a RF-DC conversion efficiency of 57% at 2.45 GHz and of 72% at 2.1 GHz, respectively for the first and the second rectifier.
