Abstract

Nowadays the demands for radio frequency identification (RFID) have been widely used in many services in the industry because of its more capable in many ways. This makes               the design and development for RFID system is numerous. In particular, the premier label antenna as well known as a Tag, which is one element that is important. Due to it is a device that allows the RFID system can be communication between them. The researchers are interested in studying the identification system with radio frequency extensively. The system can be utilized in a wide range of aspects. Furthermore, it can be development for                  signal transmission of the RFID system good to be most effective. In this research presented the design of the novel RFID Tag for the identification system with radio frequency. The antenna      is designed to provide effective and appropriate to the requirements for the RFID system as well as possible. The propose antenna for the identification system with radio frequency is designed on FR4 substrate, since it is small size, easy fabrication and low cost. In antenna design, we analyze and simulate Tag antenna by using CST program. To confirmed simulation results,        the purposed Tag antenna will be realized and experimented. In measurement, it found that antenna has bandwidth 14.25 % covered the operating frequency for RFID system at 2.45 GHz. This antenna has omni-directional radiation patterns and gain is about 4.95 dB with return loss less than -10 dB over the frequency range of 2.28 – 2.63 GHz. The advantage of the proposed Tag antenna is that it can be used in identification system with radio frequency more efficiently.
