| Abstract(in English) | In this paper, we discuss the change of read range between a UHF passive RFID tag and a reader when a tag is close to another tag because of a power-mismatching arises between a tag's antenna and a tag's IC. The read range is determined by the strength of the forward and reverse link. In this research, we calculate received powers of a tag and a reader with states of matching between a tag's antenna and a tag's IC. In addition, we measure received powers of a tag and a reader under the same condition of the calculation and clarify which the forward link or reverse link restricts the read range. As a result, it becomes clear that the read range is determined by the forward link finally. |
