ABSTRACT

In this era of the Internet of Things, we designed a rectenna working at 5.8 GHz in order to solve the finite things about battery-powered wireless sensor. First, an E-shape embedded microstrip feed antenna by HFSS software has been designed, then a technique called “offset correction” to balance the deviation between theory and simulation was proposed. It effectively spanned the gap between simulation and measure, so that the physical antenna could achieve the design specifications. Then, an impedance measurement model for rectifier circuit was established, which was applied to the vector network analyzer with limited output power. Finally, rectifier’s error was analyzed by “mirror de-embedding impedance measurement”.
