Portable electronic device

The invention relates to a portable electronic device, substantially in the form of a card, provided with an integrated circuit which has a first side and an opposite second side, comprising on the first side a first electrically conductive face and on the second side a second electrically conductive face, the device further comprising a first and a second electrically conductive structure, the first structure being situated on the first side of the integrated circuit and the second structure being situated on the second side of the integrated circuit, data and energy being transferable to the integrated circuit from a base station via said structures and faces. The electronic device () comprises an integrated circuit () with a first () and a second side (), on both sides () of which first and second conductive areas () are present. The electronic device () further has a first () and a second () conductive structure, which () are present on a-preferably enveloping-layer () of dielectric material. Signal and power to and from the integrated circuit () are transferred through capacitors () formed by the conductive areas () and the conductive structures () and an intermediate layer () of dielectric material. The integrated circuit () may contain a protective layer () in the second conductive area ().
