Antennas can always be affected by the attached materials. Such a property is here integrated with RFID technology of designing a passive RFID tag which is sensitive to a chosen object material. A good sensing ability will help the tag bonding up with the chosen material, which will benefit material security a lot. To achieve a high tag‐object bonding sensitivity, a fragmented‐type tag is introduced here. When permittivity of attached object material changes a little bit, readability of the tag will degrade rapidly. The sensitive properties are investigated by simulated and articulated experimentations. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:318–323, 2017
