Problems solved by technology
 Example 1
 like figure 1 As shown, the rectenna includes a microstrip receiving antenna 1 and a microstrip rectifying circuit 2 , which are connected through a joint 3 . When microwaves in the RFID frequency band are transmitted to the microstrip receiving antenna 1 , the microstrip receiving antenna 1 can receive microwave energy and transmit the microwave energy to the microstrip rectifier circuit 2 through the connector 3 .
 like figure 2 , 3 As shown, the microstrip receiving antenna 1 includes a floor 4, a radiation plate 5, a pillar 8 and an SMA head 6 for coaxial feeding. The gap 7 exists, the floor 4 is connected to the radiation board 5 through the pillar 8; the SMA head 6 of the coaxial feed passes through the floor 4 and connects to the radiation board 5
 like image 3 As shown, the floor 4 includes a dielectric layer 41 and a copper clad layer 42, and the bottom surface of the dielectric layer 41 is attached to the top surface o...
