The present invention relates to a USB communications terminal, and in particular, to a data card. The USB communications terminal includes a USB connector and a printed circuit board PCB, where the USB connector includes a metal housing, a radio-frequency signal feedpoint is disposed on the PCB, and the radio-frequency signal feedpoint is electrically coupled with the metal housing. According to the USB communications terminal in the present invention, a radio-frequency signal feedpoint is electrically coupled with a metal housing of a USB connector, so that the metal housing of the USB connector is used as an antenna or a part of an antenna of the USB communications. Therefore, no antenna needs to be additionally designed on the USB communications terminal, thereby saving space of the USB communications terminal and also reducing costs. |
