The present invention relates to a rectifying electronic circuit, for instance an electronic carrier for antennas for a smartcard, comprising two electronic circuits. A first electronic circuit comprises a first wire antenna configured to provide energy to an electrical load for a smartcard and a first diode connected to the first wire antenna and having a first forward bias; a second electronic circuit comprises a second wire antenna configured to provide energy to the electrical load and a second diode connected to the second wire antenna and having a second forward bias. An induced current is generated in the first wire antenna and in the second wire antenna when they are exposed to an alternating magnetic field. The first diode and the second diode are positioned on the rectifying electronic circuit in such a way that only one diode has a forward bias that allows flowing of said induced current, given a predefined direction of the alternating magnetic field, so that the induced current can flow alternatively through the first electronic circuit or in the electronic circuit to provide energy to the electrical load in the form of a rectified signal.
