Abstract
Rectifier is a fundamental element of a rectenna system that converts RF energy to direct current (dc). We proposed a triple-band rectifier using a novel matching technique and single series diode topology. First, we designed a single band rectifier and then converted it into a dual- and triple-band rectifier by introducing an appropriate transmission line and shorted stub, respectively, to convert simultaneously multiple RF signals into dc. The proposed rectifier operates at the popular frequency bands of 1.95, 2.7, and 5.8 GHz with power conversion efficiency (PCE) of 65.5%, 62%, and 57.1%, respectively, using a single impedance matching circuit.
