Abstract :

Radio Frequency Identification is the method identifity object  individual by use radiowave. Use this technology we can collect information for production, time and trades. This system is include three section tag, reader and host computer that antenna goal in a RFID tag is couple of chip with reader  magnetic fild. In this paper inductively coupled RFID antennas in two different structures, namely arc-shape and dual-body configurations, are presented. High input resistance can be easily achieved with these structures to realize conjugate impedance matching with some tag chips. 1.99dBi and 5.62dBi directivities at 915MHz are also observed.
