摘要： A single antenna with a shared radiator includes a radiator unit, a feed-in unit, a sensing module and a ground unit. The feed-in unit is coupled with the radiator unit and used to send or receive radio frequency signals together with the radiator unit. The sensing module is connected to the radiator unit and used for sensing a distance between the radiator unit and an object by the radiator unit. A distributed capacitor structure is formed between the ground unit and the radiator unit.

摘要： A wireless electronic label comprises a display module, a rectenna module and a control drive module. The display module has a display surface. The rectenna module is disposed on the display surface of the display module. The rectenna module is used to receive an electromagnetic wave signal and convert it into an electrical energy signal. The rectenna module is made of light-transmitting electronically conductive material. The control drive module is used to convert the electrical energy signal into electrical energy to power the wireless electronic label and to send a command signal to the display module. The display module is further used to display a label signal on the display surface according to the command signal.
