Problems solved by technology

The advantage of using a diversity antenna is that it can increase the download rate of the data card. However, because the diversity antenna requires a certain amount of space to implement, the size of the current data card is usually relatively large, which also causes the cost of the data card while the appearance is not beautiful. increase

Embodiment Construction

[0018] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The invention provides a data card, which forms a diversity antenna of the data card by electrically connecting the joint with the metal shaft of the joint, and forms the antenna of the data card together with the main antenna of the data card for data interaction with a user terminal.

[0020] refer to figure 1 and figure 2 , figure 1 It is a schematic structural diagram of the first implementation mode in the first embodiment of the data card of the present invention; figure 2 It is a schematic structural diagram of the second implementation manner in the first embodiment of the data card of the present invention.

[0021] The data card provided in this embodiment includes a casing 10, a PCB board 20 and a main antenna 30 disposed in the inner cavity of the casing 10, and is fixedly connected to the casi...

Abstract

The invention discloses a data card. The data card comprises an enclosure, a printed circuit board (PCB) and a main antenna which are arranged in a cavity in the enclosure, a connector which is fixedly connected with the enclosure, and a connector metal rotation shaft which is arranged in the enclosure and electrically connected with the connector; and the connector metal rotation shaft and the connector form a diversity antenna of the data card. The invention also discloses a data interaction system which comprises the data card and a user terminal. By adopting the scheme, the diversity antenna is not needed to be set independently, so that the dimension of the data card is reduced, and the data card is attractive in appearance; and therefore, the production cost of the data card is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a data card and a data interaction system. Background technique [0002] With the rapid development of wireless communication technology in recent years, personal data cards have been widely popularized and applied. When this type of data card works, it is connected to the user terminal equipment (notebook, netbook) through the data connector (USB head) and then connected to the network. However, since the material of the user terminal equipment is usually metal (LCD screen and main board), when the data card is close to this type of material, the antenna of the data card will be affected by the metal plate, resulting in a decrease in the radiation efficiency of the antenna and making the antenna The distortion of the radiation pattern will eventually affect the user's use. [0003] In order to increase the rate at which users use wireless terminal products, ante...
