A kind of antenna and notebook computer

Abstract

The invention discloses an antenna and a notebook computer. The antenna includes: a first antenna part, which is arranged on the shell of the optical drive; a second antenna part, which is arranged on the optical disk tray of the optical drive; a substrate, which is arranged on the notebook computer and Corresponding to the top and bottom of the optical drive, the substrate is provided with a first connection circuit and a second connection circuit that are both electrically connected to the wireless network card of the notebook computer; the first connection circuit is connected to the first antenna part, and a switching part is provided in the first connection circuit ; When the disc tray retracts into the shell, the second antenna part is electrically connected to the second connection circuit, and at the same time the switching part acts to disconnect the first connection circuit from the wireless network card; when the disc tray pops out of the shell, the second antenna part It is disconnected from the second connection circuit, and at the same time, the switching part acts to electrically connect the first antenna part to the wireless network card. The antenna of the invention can be installed in a notebook computer with an all-metal casing and can ensure stable sending and receiving signals without opening an antenna window.

Description

technical field [0001] The invention relates to an antenna, in particular to an antenna applicable in a notebook computer with a full metal casing and a notebook computer with the antenna. Background technique [0002] At present, many notebook computer products require metallic appearance and multi-functional performance, so there are fewer and fewer places where notebook antennas can be placed. Moreover, the metal casing has a great influence on the radiation field of the antenna, and it is necessary to open an additional antenna window or require a large antenna clearance area to meet the user's wireless use requirements. However, opening the antenna window is not conducive to the appearance and craftsmanship of the notebook computer, and the cost is very high; and if the headroom area of ​​the antenna is increased, it will directly affect the placement space of other components. [0003] For the above problems, there are two existing solutions. The first one is: all the...

Problems solved by technology

[0004] The disadvantage of this solution is that it requires an injection molding (insert molding) process, and the process yield rate is low when this process is applied to a notebook computer. In addition, the cost of opening the antenna window is relatively high

[0006] The disadvantages of this solution are: the hinge cover is generally closer to the motherboard of the notebook computer, and the installation of the antenna there seriously affects the system transmission rate, and the noise is relatively large. If you want to solve the noise impact, you need higher costs.
