An insert for a chip card includes a body provided with a cavity in which is inserted an electronic module provided with a microelectronic chip connected to an inductive or capacitive coupling. The body has a stack of layers at least a first layer of which comprises a first booster antenna and a second layer of which comprises a second booster antenna, the various booster antennas being coupled together inductively and/or capacitively, and at least one of the booster antennas being coupled inductively and/or capacitively with the coupling of the module. The body furthermore comprises at least one metal plate disposed between two layers of ferrite, the first and second booster antennae and the metallic plate being arranged in such a way that at least one of the two booster antennas and the electronic module remain coupled together inductively and/or capacitively, despite the presence of the metal plate.
An insert for a contactless or hybrid contact/contactless chip card, said insert including a body provided with a cavity in which an electronic module provided with a microchip that is connected to a capacitive or inductive coupling means is located, wherein the body is formed from a stack of layers at least one first layer of which includes a first booster antenna and one second layer of which includes a second booster antenna, said booster antennae being coupled together inductively and/or capacitively, and at least one of the booster antennae being coupled inductively and/or capacitively to the coupling means of the module, and wherein the body furthermore includes at least one metal plate that is placed between two ferrite layers, said first and second booster antennae and said metal plate being arranged so that at least one of the two booster antennae and the electronic module remain inductively and/or capacitively coupled to each other despite the presence of the metal plate.
