Nowadays, due to the increasing consumer demand for mobile computing, notebook PCs (personal digital assistants) and personal digital assistants (PDAs), which are convenient to carry around, are becoming more and more popular with consumers. At the same time, with the increasing demand for mobile computing, wireless network modules that can connect to the Internet at any time and place have also become the basic equipment of notebook computers. These wireless network modules such as 802.1a, 802 · lib, 802 · llg and other wireless network interfaces are collectively called WiFi (Wireless Fidelity) interfaces, and their operating frequency band is 2.4GHz (802.11b, 802 · llg) With 5GHz (802.11a). In the frequency band used by the GSM (Global System for Mobile Telecommunications) mobile phone system, such as _MHz, 1800MHz, 1900MHz, 2100MHz, etc., if it is within the radio wave coverage area of the mobile phone base station, it can also be used by mobile phone operators. Provide the ship to achieve the purpose of Internet access. In addition to the need for Internet access, the popularity of scale peripherals such as scale keyboards, wireless mice, and so on, has also made notebook computers often equipped with wireless communication modules that can transmit wireless communication modules, such as Bluetooth branches ( Bluet〇th Module), its operating frequency band is 2.4 GHz. In addition, the global positioning system (Global Positioning System, GPS) is also often used to calculate the rainbow, in order to achieve navigation, and the frequency

TP050098-TW 5 M276331 segment is 1.57GHz. See figure 5. The fifth figure is a conventional electronic device 9 having a plurality of antenna modules of different frequency bands. The conventional electronic device 9 may be a notebook computer or other mobile computing devices. The conventional electronic device 9 includes a wireless network antenna module 2 and a GSM antenna module & and a wireless communication antenna module 41. The wireless network antenna module 2 and the GSM antenna module 31 and the wireless communication antenna module 41 are installed on the casing 91 of the conventional electronic device 9 in a built-in manner. Because these antenna lions need to be installed separately in the electronic equipment M_ pre-hybrid, the electronic equipment Wei Liuxiang is dumped to set up these unscrupulous Tianlai groups in the county, so it will increase the design of the electronic equipment mechanism. manufacturing cost. On the other hand, because these antenna modules are independent of each other, it is necessary to use a different connection in the electronic design part to connect to the processing device 4 in the electronic device, which will also increase the manufacturing cost of the electronic device. To sum up, because the manufacturer ’s wireless transmissions include wireless Internet access devices, wireless peripherals, and global fixed-line devices, so on a mobile computing device, it is often necessary to have a wire pool. . f Knowledge shooting, tree computing devices, such as note brains, various unconnected antenna modules occupy different positions on the pen computer. In this way, not only the positions of multiple antenna modules need to be reserved in the organization, but also each antenna module «requires a separate transmission channel for the arithmetic processing device in the Echuan notebook computer. This will not only increase the manufacturing cost of related structures, but also must use a variety of different transmission cables to transmit signals from different antenna modules. Pursuing light and thin pen-type computer design requirements will increase design difficulty and reduce manufacturing costs. [New content]
