Abstract

A wireless data card and an electronic device, which relate to wireless communication equipment, are adapted to solve the technical problem that the exposed size of an antenna of a built-in wireless data card used in an existing electronic device is too small to achieve a desired performance of receiving radio signals for the antenna. The wireless data card includes a data card body and an antenna electrically connected to the data card body. An elastic structure capable of enabling the antenna to extend out of the data card body and also retract into the data card body is disposed between the data card body and the antenna. The electronic device includes a device case provided with a device port and the wireless data card disclosed above in this disclosure, in which the wireless data card is disposed in the device case and relative to the device port, and the antenna is disposed relative to the device port. This disclosure is applied for transmitting wireless data communication signals.

Claims
