摘要：During grain storage, it is necessary to monitor the temperature, humidity and other environmental factors, so a large number of sensors are needed. The power supply to the sensor requires a lot of cables, which is very cumbersome to arrange a large number of cables. If battery power is used, the battery needs to be replaced regularly. The sensor can be powered by microwave wireless power transmission technology. This paper analyzes the feasibility of this method during grain storage from the perspective of transmission loss, introduces and designs the rectenna, and uses HFSS software to simulate the rectenna. ? 2021 ACM.
