An electronic device having a function of automatically switching operation modes includes a circuit board, a first case, a second case, and a connector. The second case is assembled with the first case to form an accommodating space. The circuit board is disposed inside the accommodating space. The connector is disposed on the first case and applied for the circuit board. The connector can include a first contacting portion and a second contacting portion. The second contacting portion is equipped with the first contacting portion. The first contacting portion is pressed by the second case and drive deformation of the second contacting portion, and the second contacting portion contacts the circuit board to keep in a first operation mode. When the second case is removed from the first case, the second contacting portion is resiliently recovered and the circuit board is switched to a second operation mode.

Automatically switching operation modes electronic device

A directional antenna including a ground plane, a feeding element and a radiating element is provided. The feeding element is adjacent to the ground plane and includes a feeding point. A coupling gap is formed between the radiating element and the feeding element, and the radiating element includes a coupling point. Both the coupling point of the radiating element and the feeding point of the feeding element are at the perpendicular line of a ground plane. Further, a distance between the coupling point and an open end of the radiating element is smaller than 0.16&#x3bb; of a resonant frequency of the directional antenna.
