Résumé

In this paper, a 1.85 and 2.45 GHz dual-band dual-polarized rectenna for RF energy harvesting is designed and experimentally validated. The proposed rectenna consists of stacked circuits for both antenna and rectifier. The antenna is a dual-polarized array consisting of 4 single elements. Each polarization is associated with one frequency band of operation. The rectifier is built around a diplexer for the two input frequencies 1850 and 2450 MHz and a series-mounted Schottky diode. The insertion losses of the diplexer are significantly reduced which improves the conversion efficiency. The proposed rectenna is fabricated and measured, the experiments are in good agreement with the simulations. More than 500 and 400 mV dc voltage were measured across an optimal 2 k-Ohms load, with −8 dBm input power, at 1.85 and 2.45 GHz, respectively.
