Description

Laptop with printed circuit board antenna

technical field

The utility model relates to a notebook computer equipped with a printed circuit board antenna, in particular to a notebook computer equipped with a printed circuit board antenna which enhances the signal receiving effect and provides good communication quality.

Background technique

The development of information technology is quite rapid, especially the research and development of wireless communication, which has attracted the attention of the industry. In recent years, there are many wireless communication standards, most of which are carried out in digital transmission. There are many types of digital communication modes, especially the wireless network (Wireless) communication mode is the focus of the development of related industries. The advantage of wireless network (or wireless local area network, Wireless Lan, WLAN) is that the transmission distance is the farthest in the current wireless communication, generally speaking, it can reach more than 30 meters, and the data transmission bandwidth is also the largest. Up to 2Mbps, and can climb up to about 54Mbps depending on the demand. Faced with the increasingly popular multimedia-related applications, the wireless network communication mode can provide sufficient communication bandwidth, and it can be said to be a rising star in the future. Especially in countries with extremely high real estate values, because there is no need to design indoor wiring, many local companies or multinational companies have adopted wireless network operating systems one after another. This kind of wireless network operation mode frees users from the office space, which not only improves the productivity and efficiency of employees, but also reduces the office space required by users, effectively reducing the overall operating costs of enterprises.

At present, handheld data processing devices such as Personal Digital Assistant and Notebook, in addition to using an external wireless network card for wireless transmission operations, there are also products with built-in wireless transmission functions, depending on the type of antenna , can be roughly divided into two categories using dipole antennas and using planar antennas such as printed circuit board antennas.

Taking a product with an exposed antenna as an example, the traditional method is to place the dipole antenna in a storage slot on the side or top side of the notebook computer in such a way that it can be movably rotated out or retracted, as shown in the patent in Taiwan, China. Announcement No. 454962 is its representative. As for the products that install the antenna inside, the general method is to bury it on the rear side, sides or top side of the notebook computer display, or bury it at the hinge where the main body of the notebook computer connects with the display. For the approach of the hand parts of the host body, such as China Taiwan Patent Publication No. 479851 and No. 527749 disclose related technologies.

The design of embedding the antenna in the main body of the notebook computer or inside the display has the advantages of beautiful appearance and easy portability. However, the design of disposing the antenna on the top side often results in a corresponding increase in the size and thickness of the display, which makes the whole notebook computer look bulky and bulky. The design of installing the printed circuit board antenna on the rear side, the two sides, the armrest of the host body or the shaft will affect the signal receiving angle of the printed circuit board antenna and cause a dead angle for signal reception, resulting in a decrease in communication quality.

Above-mentioned is known technology or the unresolved problem of commercially available product for a long time, should try to get rid of.
