Passive RFID tag positioning using 1D stripline-shaped antenna

Radio Frequency Identification (RFID) technology is widely employed for tagging to real objects in our world including books in a library, merchandises in a supermarket, chemical bottles in a laboratory etc. To manage the data about the tagged physical objects, their positions can be key information. This paper proposes a method to identify passive RFID tag location. The proposed method requires only a simple stripline-shaped antenna as a RF component. Other elements composing our localization system are one RFID reader and electric circuits which deal with at most several kilo hertz signals. The paper presents a principle of our proposed method and a fundamental experiment.
