An antenna structure applied in a wireless communication device including a hinge, the antenna structure includes a feed portion, a first radiation portion, and at least one ground portion; an end of the first radiation portion is electrically connected to the feed portion, another end of the first radiation portion is spaced from the hinge with a gap; the antenna structure generates a radiation signal in at least one radiation frequency band when the feed portion feeds electrical current to the first radiation portion and the hinge couples the electrical current from the first radiation portion. A wireless communication device having the antenna structure is also provided.

Antenna structure and wireless communication device using same

An antenna structure applied in a stylus includes a first radiating portion, a second radiating portion, and a main body. The second radiating portion corresponds to the first radiating portion. The main body covers the first radiating portion and the second radiating portion. The first radiating portion electrically connects to a feed source to feed in current, the first radiating conducts the current to activate a first mode to generate radiating signals, the main body couples the current from the first radiation portion, the second radiating portion couples the current from the main body, the first radiating portion, the main body, and the second radiating portion conduct the current and connect to ground to activate a second mode to generate radiation signals. A stylus using the antenna structure is also provided.

An antenna structure includes a main body, a first radiating body, and a second radiating body. The main body includes a feeding portion, a connecting portion, a first coupling portion, and a second coupling portion. The connecting portion is perpendicularly connected to the feeding portion. The first coupling portion and the second coupling portion are positioned at two opposite sides of the connecting portion. The first radiating body is configured to surround and resonate with the first coupling portion. The second radiating body is configured to surround and resonate with the second coupling portion.

Antenna structure and wireless communication device using the antenna structure

An antenna structure includes a feed terminal, a first antenna, and a second antenna. The first antenna includes a first antenna portion connected to the feed terminal, and a second antenna portion connected to the first antenna portion. The second antenna is substantially parallel to the second antenna portion and cooperatively defines a space with the second antenna portion.

A wireless communication device includes a base board, a display module, and a metal member. The display module is located on the base board. The metal member includes a frame and a metal body. The frame surrounds the display module. The metal body extends from the frame, and is spaced from the display module to reduce electromagnetic interference between the at least one metal body and the display module.

Wireless communication device

Antenna structure includes a feed section, a first radiator, and a second radiator. The first radiator includes a first radiation portion, a ground end, a second radiation portion, the first radiation portion is spaced from the feed end, the ground end is connected between the first radiation portion and the second radiation portion. The second radiator is located below the second radiation portion, and includes a first extending strip, a ground portion, a second extending strip, and a third extending strip. The first extending strip is spaced from the feed end, the second extending strip is connected to the first extending strip and extends along the first extending strip, and the ground portion is connected to a junction of the first extending strip, the second extending strip, and the third extending strip.
