Abstract

A data card includes a casing provided with a circuit board therein. One end of the casing is provided with a plug electrically connected with the circuit board. The data card further includes a connecting part and a cap part. One end of the connecting part is connected with the casing, while the other end is connected with the cap part. The cap part can cover the plug. An antenna which is electrically connected with the circuit board is provided on the connecting part and/or the cap part. The invention mainly use in wireless data signal receiving or transmitting device.
