摘要： The present invention relates to an expansion card and an antenna structure for this expansion card for wireless data transmission, which card (C) comprises a card part (1) to be placed inside an expansion card interface of an electronic device, and which antenna part for receiving and transmitting of signals comprises at least one electroconductive, radiating antenna plane (31) and a ground plane (32) arranged parallel to the same, at a distance, as well as a dielectric (33) between said planes. In the invention, for improving the antenna properties, said antenna structure is placed in a housing part (2) which is connected to the end of the card part (1) and which comprises a cover structure (21) and a bottom structure (22), for extending said antenna structure at least partly outside said interface, wherein the antenna plane (32) is arranged on the side of the cover structure (21), the ground plane (32) is arranged on the side of the bottom structure (22), and said dielectric is arranged a free clearance.
