| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed and investigated 5GHz-band wireless-LAN based simple beamforming wireless IoT communication system with Wi-Fi backscatter communication for beam tracking. In this system, an access point (AP) is assumed to be placed on the base of machine tool or robot in the factory and a sensor node (SN) is assumed to be put on the moving/rotating tool or the arm of the robot. In this paper, a miniaturized antenna module for Wi-Fi backscatter SN is designed and fabricated. The link design and the received Wi-Fi backscatter power measurement are carried out using fabricated antenna module. The design result shows that the maximum communication distance between AP and SN is 2.7 m under the condition of 17 dBm transmit power (CW) from AP and $-80$ dBm sensitivity of AP’s receiver. This is a invited presentation for the research encouragement award received for the presentation at the Technical Committee on Smart Radio (SR) in July 2020. |
