Abstract
An antenna structure for network card used with a notebook computer includes an antenna retractably connected to the network card. The antenna is in an open-circuited state when it is at a position retracted in the network card, and in a close-circuited state when it is at a position projected from the network card. The network card can therefore be normally plugged into a network card slot of the notebook computer without the need of removing it from the computer when the latter is not connected to a network or is to be positioned in a bag. The problems of missing network card and of damaged, worn or poor-contacted terminal of the network card due to frequent plugging and unplugging of the network card can therefore be avoided.
