Abstract
An RFID tag is provided for transmitting and receiving a communication signal. The RFID tag includes a base material, an antenna pattern disposed on the base material, and a high-loss member. The high-loss member is disposed adjacent to the antenna pattern and has a high loss at a frequency higher than a frequency of the communication signal, compared with the antenna pattern and the base material. When the RFID tag is subjected to an electromagnetic wave heating microwave, the high-loss member generates heat and the antenna pattern is cut at a position of the high-loss member.
