A mobile device with high radiation efficiency includes a ground element, a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, a dielectric substrate, a speaker body, and a cable. The first radiation element and the fourth radiation element are coupled to the ground element. The second radiation element and the third radiation element are coupled to a feeding point. An antenna structure is formed by the first radiation element, the second radiation element, the third radiation element, and the fourth radiation element. The speaker body has a first vertical projection on the dielectric substrate, and the first vertical projection at least partially overlaps the third radiation element. The cable is coupled to the speaker body. The cable has a second vertical projection on the dielectric substrate, and the second vertical projection does not overlap the antenna structure at all.

Mobile device with high radiation efficiency

A back cover includes a metal body having a first side, a second side, and a groove that is formed at the first side. The metal body further has a first radiator, a second radiator, and a ground radiator. The first radiator is disposed in the groove, and has a main portion and a support portion that cooperatively form a T-shape. The main portion includes a feeding end adjacent to a closed end of the groove. The second radiator is adjacently connected to the groove and is defined by the first and second sides, and an edge of the groove. The ground radiator is formed by a portion of the metal body excluding the first and second radiators. The second radiator and the support portion are connected to the ground radiator. The first and second radiators, and the ground radiator are serve as an antenna structure.

Back cover for electronic device and electronic device

A mobile device and antenna structure thereof are provided. An antenna structure is placed next to a pivot structure of the mobile device and a parasitic element is placed next to a high-frequency radiation element extending from a feeding element, so as to resonate with the high-frequency radiation element to generate a resonant mode for compensating the lack of a high-frequency bandwidth.

Mobile device and antenna structure thereof

A mobile device includes a ground element and an antenna structure. The antenna structure includes a ground branch, a feeding branch, a low-frequency radiation branch, and a high-frequency radiation branch. The feeding branch is coupled through the ground branch to the ground element. The low-frequency radiation branch is coupled to the feeding branch. The high-frequency radiation branch is coupled to the feeding branch. The low-frequency radiation branch has a meandering structure for reducing the SAR (Specific Absorption Rate) of the antenna structure.

Mobile device

An antenna structure includes a ground element, a first radiation branch, and a second radiation branch. The first radiation branch has a first end and a second end. The first end of the first radiation branch is coupled to a signal source. The second end of the first radiation branch is open. The second radiation branch has a first end and a second end. The first end of the second radiation branch is coupled to the signal source. The second end of the second radiation branch is coupled to the ground element. The length of the second radiation branch is substantially equal to that of the first radiation branch.

Antenna structure

A mobile device includes a metal body element, a feeding element, and a second antenna. The metal body element is substantially a planar structure and has a slot, wherein a first antenna is formed by the slot of the metal body element. The feeding element extends across the slot of the metal body element, and is coupled to a first signal source. The second antenna is substantially located inside the slot of the metal body element, and is coupled to a second signal source. The slot is used as a portion of a resonant structure of the second antenna in order to reduce a total size of the first antenna and the second antenna.
