Problems solved by technology

[0016] However, for the above-mentioned wireless communication circuit structure, one of the characteristics lies in the integrity of the wireless communication signal line and the grounding line. The loss (Loss) is close to 0dB, which has a good wireless communication effect. However, due to the integrity of the wireless communication signal line and the grounding line, the internal system ground and the external ground cannot be separated, that is, the above-mentioned wireless communication circuit structure has no way to provide resistance. Electromagnetic susceptibility (EMS) interference, anti-electrostatic discharge (ESD) and ability to prevent leakage, which will cause internal systems to be affected by electromagnetic susceptibility interference and electrostatic discharge, resulting in system failure or even damage

[0017] In order to provide anti-electromagnetic susceptibility interference, anti-static discharge and anti-leakage capabilities, it is necessary to separate the wireless communication signal line and the grounding line in the above-mentioned wireless communication circuit structure, in the wireless communication frequency range of 800MHz to 6GHz The loss in the medium is greater than 30dB, that is, the effect of wireless communication cannot be provided

[0018] In summary, it can be seen that there have been problems in the existing wireless communication circuit structure for a long time, such as anti-electromagnetic susceptibility interference, anti-static discharge, and anti-leakage functions and wireless communication functions. Therefore, it is necessary to propose an improved technology means to solve this problem
