Abstract
A microwave-safe inlay includes an RFID chip, an antenna, and a substrate having special shielding surfaces. These shielding surfaces are arranged in such a manner that the shielding surfaces block microwave radiation, while communication in the HF/NFC and UHF range continues to be possible. The inlay is thin, mechanically and thermally durable, and is used with or without shielding elements to be additionally placed under the inlay. The inlay is intended for use with and integration into reusable microwavable dishes, so as to allow reliable identification and writing or reading of additional information.
Claims20
A microwave-safe inlay, comprising an RFID chip, an antenna connected with the chip electrically or magnetically, and a first substrate arranged surface-parallel, having a plurality of discrete shielding surfaces, wherein the RFID chip, with the antenna, is applied to the first substrate, and two adjacent shielding surfaces have an interstice between the two adjacent shielding surfaces, in each instance,
- wherein the shielding surfaces are arranged as separate elements, spaced apart from one another, on the first substrate, in at least one pattern layer, in which the interstices between the adjacent shielding surfaces are oriented relative to one another so as not to align, in such a manner that the adjacent shielding surfaces block every straight-line path through the shielding surfaces that runs exclusively along the interstices.
