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.

The present invention relates to an electronic carrier for antennas for a smartcard comprising an antenna substrate, a first wire antenna configured to provide energy to a lighting element for a smartcard, and a second wire antenna configured to provide energy to an electronic module for contactless data transfer for a smartcard, wherein the first antenna and the second antenna are formed on opposite sides of the antenna substrate. The present invention also refers to a lighting device for a smartcard comprising a lighting element configured for illuminating a portion of the smartcard and a single diode suitable for providing energy to the lighting element when connected to an energy harvesting antenna. Furthermore, the present invention refers to a pre-laminated structure for a smartcard and a smartcard comprising said electronic carrier and / or said lighting device.

The present invention relates to an RFID tag having a wire antenna having improved transmission / reception characteristics and, more particularly, to an RFID tag in which an RFID chip is mounted and connected to a substrate to which an antenna formed of a conductive high-strength metal wire and a meandering loop pattern are applied, and an antenna connection part is epoxy-molded. The substrate of the RFID tag of the present invention for solving the technical problem may be characterized in that an antenna pattern having a loop structure connecting two terminals of the RFID chip is formed thereon.

An antenna structure for radiating a radiofrequency signal. The antenna structure comprises a conductive element having a rim with a rim edge and a gap. A wire antenna element is positioned to partially overlap the rim by extending in parallel with the rim edge and partially overlap the gap. The rim edge is, in an assembled and ready to operate state of the antenna structure, electromagnetically exposed and the wire antenna element is configured such that a radiofrequency current induced or flowing through the wire antenna element induces an electric field in the overlapped portion of the rim and the edges of the gap, causing the overlapped electromagnetically exposed rim edge of the portion of the rim and the edges of the gap to radiate the radiofrequency signal responsive to the radiofrequency current.
