An electronic device including a touch screen, a first back cover, a transmitting antenna and a receiving antenna is provided. The first back cover includes a frame and a cover body. The transmitting antenna is adjacent to an edge of the touch screen and has a feeding point for receiving a feeding signal. The receiving antenna is adjacent to the cover body of the first back cover and is electrically connected to a ground plane. The receiving antenna and the transmitting antenna are spaced apart by a coupling distance, and a signal from the receiving antenna is transmitted to the feeding point through the coupling distance and the transmitting antenna.

Electronic device

A mobile communication device includes a substrate, a frame, a ground plane, and an antenna element. The substrate includes a first surface and a side wall. The frame includes a frame portion adjacent to the side wall. The ground plane is arranged on the first surface and includes a notch. An opening of the notch faces the frame portion. The antenna element includes a first radiation portion having a feeding point, a second radiation portion electrically connected to the ground plane, a third radiation portion electrically connected to the first radiation portion, and a fourth radiation portion electrically connected to the second radiation portion. Orthogonal projections of the first and second radiation portions on the first surface are located in the notch of the ground plane, and the third and fourth radiation portions are located on the frame portion or the side wall of the substrate.

Mobile communication device

A mobile communication device includes a substrate, a metal frame, a feeding portion, and a parasitic portion. The substrate includes a ground plane and a non-ground area. The metal frame surrounds the substrate and includes a plurality of gaps to form a first frame element and a second frame element separated from each other. The first frame element is electrically connected to the ground plane. The feeding portion and the parasitic portion are located in the non-ground area. A first end of the feeding portion is configured to receive a feeding signal, and a second end of the feeding portion is an open end. The parasitic portion is electrically connected to the second frame element and the ground plane. The feeding portion, the second frame element, and the parasitic portion of the mobile communication device constitute a loop antenna.
