This paper proposes a rectifying antenna (rectenna) for operation in the ISM (Industrial, Scientiflc and Medical) band centered at 2.45GHz. It consists of a modifled circular monopole loaded with a rectangular ring and a half-wave rectifler. Numerical and experimental data are reported and discussed. From measurements, it is demonstrated that when the power density incident on the monopole is 155"W/cm 2 , the device here presented exhibits values of the RF- to-DC conversion e-ciency higher than 30% in the frequency range 2.35{2.5GHz with a maximum of about 50% at 2.45GHz.
