N2 - In this paper, the link design and measurement of received power of 5 GHz band backscatter communication are reported. The backscatter performed by the sensor node (SN) communicates using only the power of the Wi-Fi signal of the access point (AP). Therefore, there is a possibility that sufficient received power is not be obtained. We designed miniaturized antenna modules for SN with a backscatter feature and measured the received power during backscatter communication. As a result, it was possible to communicate about 2.5 m.
