Chapter 4 DOI: 10.4018/978-1-7998-0117-7.ch004 ABSTRACT This chapter presents many research works that have been carried out to deal with the problem of power supply to remote sensors. A 2.45 GHz voltage multiplier rectifer was validated to deliver 18V of output voltage with a conversion efciency of 69%. Another rectenna was fabricated at 5.8 GHz of the Industrial Scientifc Medical band and reach a measured voltage of 7.4V at 18 dBm. The third struc- ture is about a series rectifer working at 2.45 GHz associated with a microstrip low pass flter which produces a supplying voltage of 11.23V. Added to the aforementioned results, the objective in this work is to design, optimize and realize two structures: A dual band patch antenna working at 2.45 GHz and 5.8 GHz, and a compact rectifer circuit at 2.45 GHz for the power supply of low-consumption devices. This rectifer has been designed using Advanced Design System. The bridge topology was employed on an FR4 substrate. A good matching input impedance was observed and high conversion efciency was obtained. Simulation results have been validated through realization and measurements.
