Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0018] Such as figure 1 As shown, a downhole wireless communication tool includes an antenna 9 , a second coaxial cable 11A, a circuit board 12 and a first coaxial cable 11 connected in sequence. Among them, the first and second coaxial cables 11 and 11A are used for signal transmission, the circuit board 12 is used for receiving radio frequency signals, and the antenna 9 is used for transmitting signals.
[0019] Specifically, the first coaxial cable 11 is directly connected to the ground, and the ground transmits instructions to the circuit board 12. The circuit board 12 converts the instructions into wireless signals, and radiates outwards through the second coaxial cable 11A and the antenna 9. Wherein, the circuit board 12 also re...
