摘要： Device (10) to convert radio frequency electromagnetic energy, comprising an antenna (12), advantageously of the microstrip patch type, and an associated adapted multi-band rectifier circuit formed by a rectifier circuit (31) and by an adaption circuit (32) of the impedance of the load in the frequency bands concerned, to feed at least a connected electronic user device (40). The antenna (12) comprises a single radiant element (13), an associated conductive element (14) below the radiant element (13) and a reception circuit of the power received by the antenna (12). The radiant element (13) has an annular circular shape. The power reception circuit comprises at least a power divisor circuit (22) and a 90° phase shift circuit (24), Two feed branches (25) of the radiant element (13) are connected to the power divisor circuit (22) and the phase shift circuit (24), and are configured so as to generate two electromagnetic field components orthogonal and shifted 90° out of phase and therefore so as to receive a signal with any polarization whatsoever on at least three distinct frequency bands.
