A mobile electronic device includes a ground plane, a first slot, a plurality of first inductive elements, a first antenna, a second antenna, a first signal source, and a second signal source. The first slot is disposed in the ground plane to form a first ground portion and a second ground portion separated from each other. The first inductive elements are respectively connected to the first ground portion and the second ground portion. The first antenna and the second antenna respectively receive a radio-frequency signal in a predetermined band. The first signal source is electrically connected between the first antenna and the first ground portion and receives the radio-frequency signal from the first antenna. The second signal source is electrically connected between the second antenna and the second ground portion and receives the radio-frequency signal from the second antenna.

Mobile electronic device

A mobile device includes a host upper cover, a host lower cover, a metal cavity structure, an H-shaped slot antenna, and a feeding element. The metal cavity structure is coupled between the host upper cover and the host lower cover. The H-shaped slot antenna is formed on the host upper cover, the host lower cover, the metal cavity structure, the host upper cover and the metal cavity structure, or the host lower cover and the metal cavity structure. The feeding element is coupled to a signal source. The feeding element is configured to excite the H-shaped slot antenna.

Mobile device and antenna structure therein

An electronic device including a ground plane, a metal frame, a plurality of radiation elements and a switching circuit is provided. A first end of a frame element in the metal frame is connected to the ground plane, and a second end of the frame element is an open end. Each of the radiation elements is spaced by a coupling distance from the frame element. The switching circuit transmits a feeding signal to one of the radiation elements. When the feeding signal is transmitted to a first radiation element among the radiation elements, the electronic device operates in a first band and a second band through the first radiation element and the frame element. When the feeding signal is transmitted to a second radiation element among the radiation elements, the electronic device operates in a third band and a fourth band through the second radiation element and the frame element.
