Abstract: A universal serial bus (USB) type wireless data card is used for wireless communication in a multi-in/multi-out (MIMO) environment. The USB type wireless data card includes a card body. A USB connector is disposed at one end of the card body and connectable to a USB port of an electronic device. An antenna part includes first and second antennae connected to the card body such that the first and second antennae may be received in the card body and may be extended from the card body to move away from the card body and be spaced apart from the USB connector.
