Abstract: We present a new angulation method for detection of active RFID tags. Angulation method is a method for detecting a position by using angles from fixed base stations to target object of which the method detects the position. When a person cuts across the transmission path from a tag to a reader, the strength of electric wave is generally changed. The method employs fixed tags whose locations are already known. When the strengths of the fixed tag and a target tag are changed concurrently, our method recognizes an angle of the target tag as an angle of the fixed tag. In general an angulation method for electric wave needs array antenas or an antena which rotates on its axis. In contrast, our method needs only some fixed tags whose locations are already known without the needs of changing the other components of position detection system. Therefore, the method can be easily integrated with existing technologies such as RSS, TDOA, and so forth. In this paper we also describe performed preliminary experiment in order to demonstrate an advantage of our method. We could reduce about 17% errors by integrating our method to RSS method.
