New description: [New technical field] The present invention relates to a wireless device, and more particularly to an improved grounding structure between a plurality of circuit boards and an antenna in a wireless device, so that the antenna of the wireless device has better gain. . [Prior Art] Today's world is an era of booming electronics industry. With the introduction of various high-tech products, advances in mobile communication products and network products, many products are becoming smaller, more functional and more expensive. It's low-cost, and it's loved by more and more people, especially the most common mobile communication products that are closely related to our lives, such as mobile phones, personal digital assistants and Bluetooth headsets. The wide application of these mobile communication products has shortened the distance between people in time and space. With the continuous development of various mobile communication products, people have higher and higher functional requirements for mobile communication products. Whether mobile communication products provide more convenient, more efficient and more functions and services, it has become an evaluation and purchase. An important indicator of this mobile communication product. With the amazing growth rate of mobile communication devices on the market, the main component antennas installed in mobile communication devices are getting more and more attention. The antennas in the wireless communication as a window for transmitting and receiving electromagnetic energy, the electrical characteristics of the antenna will directly affect the communication. The quality, therefore, for many antenna manufacturers, they are trying their best to improve the electromagnetic wave reception of the antenna or to launch the 5 M329253 effect, in order to improve the quality of the product. As mobile communication products improve in the short, light, and easy to carry market, most mobile communications products are used with built-in antennas. In the existing mobile communication products, most of them have a plurality of separate circuit boards, and the boards have different functions. Taking a mobile phone as an example, today's mobile phones have a display module, a camera module, and a residual mode. The group, the battery module and the antenna module, and the modules are mostly disposed on different circuit boards, so that the electrical characteristics of the boards are different. When the mobile phone is used, the circuit board having the antenna module and the circuit board having the other modules are electrically connected through the wire. Because the electrical characteristics of the circuit boards are different, the electrical characteristics of the other circuit boards are The circuit board with the antenna module is affected, so that the electromagnetic wave receiving or transmitting effect of the antenna module is reduced by the electrical characteristics of other circuit boards, and the call quality of the mobile phone is also deteriorated. The reason is that the creator feels that the above-mentioned deficiencies can be improved, and he has devoted himself to researching and finally proposes a new idea of improving the antenna gain of the wireless communication device by improving the grounding structure of the circuit board and the antenna of the wireless communication device.
