Abstract: An RFID transponder including an antenna, a chip having at least one transmission and reception circuit as well as a memory, a dielectric carrier element which is covered on a first surface with a structured first metallization and which is covered on a second surface disposed opposite the first surface with a second metallization. The first and second metallizations are mutually electrically conductively connected, thereby forming the antenna. The first metallization is structured such that it forms two electric terminals of the antenna arranged on the first surface of the dielectric carrier element. The chip can be or is electrically contacted via these two terminals. An adaptation network is at least partly formed by the structuring of the first metallization and adapting the input impedance of the antenna in a conjugate complex manner to the impedance of the chip.

Abstract: The invention relates to an RFID transponder comprising: an antenna, a chip comprising at least one transmission and reception circuit as well as a memory, a dielectric carrier element which is covered on a first surface at least sectionally with a structured first metallization and which is covered on a second surface disposed opposite the first surface at least sectionally with a second metallization, wherein the first and second metallizations are mutually electrically conductively connected, thereby forming the antenna, wherein the first metallization is structured such that it forms two electric terminals of the antenna arranged on the first surface of the dielectric carrier element, and wherein the chip can be or is electrically contacted via these two terminals and is positionable or arranged on the first surface and/or is positionable or arranged at least sectionally integrated into this surface, and an adaptation network at least partly formed by the structuring of the first metallization and adaptin
