| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, positioning system for the passive RFID tag is presented. The antenna aperture is composed of 2 4-elements arrays of the circular polarized rectangular microstrip patch antennas. In order to provide electric power to the passive RFID effectively and to reduce responses of many tags, electronic scanning using Butler matrix has been used. And, transmitting and receiving antenna are used to enhance the isolation between transmitting and receiving. Responses from the tag are received by TDD receiver, and directions of arrival are estimated by the MUSIC. And, the distance between transmitting antenna and Tag are estimated by the required transmitting power according to the range. The resolution and accuracy is 17cm and 6cm in the fan-shaped area with the radius of 1m and angle of ±60°. |
