535327 V. Description of the invention (1) The present invention relates to an antenna device, and more particularly, to an antenna device that prevents the signals of other analog or digital components on the substrate from affecting the data transmission quality of the antenna on the layout. Bluetooth was first developed by Ericsson in 1994. In 1998, Intel, Lucent and other SIG (Bluetooth Special Interest Group) members jointly published the Bluetooth 1.0 regulations. At present, more than 200 companies have publicly supported Bluetooth, and it has become the de facto standard for wireless connection of mobile devices. After the Bud 1.0 specification is established, manufacturers around the world can complete product design work that includes Bluetooth technology, and perform product certification and compatibility testing. ^ The budding technology department combines the communication and information industries to develop radio transmission. The purpose is to break the restrictions of electronic and computer communication equipment. Because i * H ^ ^ ^ is necessary to grasp the products using l teeth technology, they can communicate with each other's purpose 'to cover; although 〆 笫 f; f e t ^ the disadvantages of different manufacturers and manufacturers of different standards. The wireless and baseband module chips of the electronic devices interfere with each other, change the field _ MU shell half is 2. 45GHZ. For the sake of protection, the signal is just here: = = divide the frequency band into many small parts. Bluetooth technology can be applied to various random jumps to prevent interference with telephone and personal digital assistant products, such as personal computers, mobile phones, Bluetooth modules, modules, printers, etc., all available for online service sharing Information. , ^ W combined together, use none Refer to Figure 1 Figure 1 is a block diagram showing a traditional data transmission circuit

For example, the antenna 12 'is used to transmit and receive data in the circuit M: The function of the chip module 13 is to perform data processing and hunting of = media: the transmission line "connected with the antenna 12 to achieve the operation of = In addition, the M bud chip module 13 additionally has a number of digital and analog components inside the channel 15 and the communication purpose = link 2; 'Related functions.' As mentioned above, the antenna 12 is used for transmission and reception. The signal transmission product of the transmission side 14 and the bluetooth chip module 13 as described in the transmission line 14 and the transmission line is described in detail. The frequency of the signal received by the antenna 12 is 2 45GHz. Transmission line effects are produced at such a south frequency. The coupling phenomenon of 1 pin will appear particularly clear. However, due to the limitation of the area of the circuit board U, the distance between the 15 ^ digital and analog components and the antenna 12 and the transmission line " is close to the transmission line effect described in the second paragraph, antenna 12 And the transmission line 14 will be virtual; the switching phenomenon of the nearby peripheral circuit 15 will cause the signal sent by Tianxin II = ineffective! : This. In view of this, in order to solve the mystery problem, Q es provides an antenna device. When the main purpose of the substrate is seven batches, it is necessary to avoid other problems. The analogy $ 立 f f interferes with the quality of the data signal transmitted by the antenna, so avoid placing elements that may cause coupling effects near the antenna and the transmission line.

Embodiment: Refer to Fig. 2 '. Fig. 2 is a block diagram showing data of a rain circuit according to an embodiment of the present invention. Here, a Bluetooth wafer is used as an example. The antenna device according to the embodiment of the present invention includes the following structure: The wide board JPCB 21 ′ has a plurality of peripheral circuits 25 and running wires. The antenna element is disposed on the substrate 21, and the width of the antenna element 22 is used as a boundary. It is used for external data. The transmission line 24 is coupled to the antenna element 22 to transmit the data signal received by the antenna το component 22 to the processing chip 23. The processing chip 23 is coupled to the transmission line 24 and the peripheral circuit elements 25 for receiving data signals from the transmission line 24 or transmitting the processed data as the transmission line 24 and the antenna 22 to the reception located in the external environment; Λ As shown in Figure 2, the oblique line area indicated by reference numeral 26 is a forbidden area where no other components are provided, and the boundary between the area 26 and the antenna M + is 1.5 times to 2.5 times the antenna width W, And 2 times w is better. During operation, the digital or analog components in the peripheral circuit 25 are too close to the antenna 22 or the transmission line 24, which will easily cause a coupling effect with the antenna 24 and cause the center frequency of the antenna 22 to shift: the distance of the signal transmission .
