Abstract: An antenna structure is provided, including a first radiator, a second radiator, a second coupling portion and a switch Circuit. The first radiator includes a feed portion and a first radiator body. The second radiator includes a first coupling portion, a second radiator body and a ground portion. The first coupling portion is connected to a first end portion of the second radiator body. The ground portion is connected to the second radiator body. At least a portion of the first radiator body is located between the first coupling portion and the second coupling portion. When the antenna structure is in a first mode, the switch circuit forms an electric path between the second radiator and the second coupling portion, and when the antenna structure is in a second mode, the switch circuit removes the electric path between the second radiator and the second coupling portion.

Abstract: An antenna structure includes a ground metal element, a first metal element, and a second metal element. The ground metal element has a slot. A feeding point is positioned at the first metal element. The first metal element and the second metal element are coupled to the ground metal element. The first metal element and the second metal element extend into the interior of the slot. The slot includes a first branch portion, a second branch portion, a third branch portion, and a fourth branch portion. The first metal element is disposed between the second branch portion and the third branch portion of the slot. The second metal element is disposed between the third branch portion and the fourth branch portion of the slot.

Abstract: A mobile device includes a metal back cover, a ground metal element, a feeding radiation element, and a dielectric substrate. The metal back cover has a slot. The feeding radiation element has a feeding point, and includes a first feeding branch, a second feeding branch, and a third feeding branch. The second feeding branch and the first feeding branch extend in opposite directions. The third feeding branch and the first feeding branch extend in the same direction. The feeding radiation element has a vertical projection on the metal back cover, and the vertical projection at least partially overlaps the slot. The dielectric substrate is disposed adjacent to the metal back cover. The ground metal element and the feeding radiation element are disposed on the dielectric substrate. An antenna structure is formed by the feeding radiation element and the slot of the metal back cover.

Abstract: An antenna structure includes a metal piece, a dielectric substrate, a feeding radiation element, a grounding radiation element, and a grounding metal element. The metal piece has a slot. A lower surface of the dielectric substrate is adjacent to the slot of the metal piece. The feeding radiation element is disposed on an upper surface of the dielectric substrate, and is coupled to a positive electrode of a signal source. The grounding radiation element is disposed on the upper surface of the dielectric substrate, and is coupled to a negative electrode of the signal source. The grounding radiation element is coupled through the grounding metal element to the metal piece. At least one of the feeding radiation element and the grounding radiation element has a vertical projection which at least partially overlaps the slot of the metal piece.
