Antenna structure of electronic device

The utility model discloses an antenna structure of an electric device, which comprises at least one touch-control pen groove, an antenna body and a touch-control pen. The touch-control pen groove is positioned in the electric device, the antenna body is connected with the touch-control pen groove, and the antenna body is electrically connected with the electric device, therefore, the electric device can transmit and receive signals through the touch-control pen and the antenna body. The touch-control pen is provided with a groove; and when the touch-control pen is inserted into the touch-control pen groove in the extension direction of the touch-control pen groove, the antenna body is mutually clamped with the groove on the touch-control pen so as to clamp the touch-control pen. Therefore, the touch-control pen has low probability of dropping off from the touch-control pen groove.
