Summary:
This paper describes the characteristics of microstrip antenna for transponder of Radio Frequency Identification (RFID) at Ultra High Frequency (UHF) band. The microstrip antenna is used to connect with the IC with standard ISO-18000-6A (Part ID: EM4223). The simulation tool based on Method of Moments (MoM) is used to analyze the transponder antenna. The antenna is designed to operate in UHF band from 860 to 950 MH with the advantage of simple structure and inexpensive cost. The antenna feeding structure is easily to integrate with a RFID microchip. This antenna has radiation pattern of omni-directional beam. In the analysis, the antenna１ characteristics such as radiation pattern, directivity, input impedance, standing wave ratio and bandwidth are investigated. The proposed antenna can be applied for data recording of supply chain.
