Miniaturized design of passive ultra-high frequency Radio Frequency Identification tag

The growing interest in the Radio Frequency Identification (RFID) technology is giving rise to new applications. This interest has initiated the development of new designs for RFID tag antenna. This paper presents an UHF miniaturized tag antenna, it's designed and simulated by using FR4 substrate at 915 MHz, meander line is used to design this tag, it's simulated by using CST microwave software it's found a good results of matching, radiation pattern and gain at 915 MHz.
