Abstract:
This paper proposes a rectifying antenna (rectenna) for operation in the ISM (Industrial, Scienti¯c and Medical) band centered at 2.45 GHz. It consists of a modi¯ed circular monopole loaded with a rectangular ring and a half-wave recti¯er. Numerical and experimental data are reported and discussed. From measurements, it is demonstrated that when the power density incident on the monopole is 155 ¹W/cm2, the device here presented exhibits values of the RF- to-DC conversion e±ciency higher than 30% in the frequency range 2.35{2.5 GHz with a maximum of about 50% at 2.45 GHz.
