The present invention improves characteristics of a tag antenna for RFID with a ceramic material exhibiting characteristics of a relaxor ferroelectric substance. More specifically, the present invention relates to an RFID tag that is formed of a relaxor ferroelectric substance having a dielectric constant of 3,000 or more and comprising a non-lead based oxide to have an expanded usage, and to exhibit improved orientation by forming the non-lead based relaxor ferroelectric substance in a planar disc or other shapes by a general dry-forming method or by forming the non-lead based relaxor ferroelectric substance in various shapes by powder injection molding.
