Abstract: An antenna structure of an external antenna device includes an elongated substrate, a grounding segment, an antenna segment, a matching module, and a low-frequency extending segment, the latter four of which are disposed on the substrate. The grounding segment and the low-frequency extending segment are respectively arranged on two opposite sides of the antenna segment. The antenna segment includes a feeding portion, a high-frequency portion, and a low-frequency portion. The high-frequency portion and the low-frequency portion are electrically connected to the feeding portion and the grounding segment via the matching module. The low-frequency portion and the low-frequency extending segment each has a signal path, and a total length of the two signal paths is 0.375˜0.625 times of a wavelength corresponding to a center frequency of a low-frequency band. The low-frequency extending segment is arranged apart from and is electrically coupled to the low-frequency portion.

Abstract: An antenna device includes a carrier and an antenna array. A first dual-frequency antenna structure of the antenna array includes a first conductive sheet, a first transmitting antenna, and a first receiving antenna. A first extension line passes through both two centers of two regions defined by respectively and orthogonally projecting the first transmitting antenna and the first receiving antenna onto the first conductive sheet. A second dual-frequency antenna structure of the antenna array includes a second conductive sheet, a second transmitting antenna, and a second receiving antenna. A second extension line passes through both two centers of two regions defined by respectively and orthogonally projecting the second transmitting antenna and the second receiving antenna onto the second conductive sheet. The first and second conductive sheets have a four-fold rotational symmetry relative to an intersection point between the first extension line and the second extension line.

Abstract: An antenna structure is provided. The antenna structure includes a first insulating substrate, a second insulating substrate, a first antenna, a second antenna, a third antenna, a grounding element, and a feeding point. The first insulating substrate and the second insulating substrate are spaced apart from each other. The first antenna and the second antenna are respectively disposed on two side surfaces of the first insulating substrate. The first antenna has a first line of symmetry, and the second antenna has a second line of symmetry. The first line of symmetry and the second line of symmetry have an angle there-between, and the angle is within a range from 35 degrees to 55 degrees. The third antenna and the grounding element are respectively disposed on two side surfaces of the second insulating substrate. The feeding point is connected to the third antenna and the grounding element.

Abstract: An antenna structure is provided. The antenna structure includes an insulating seat, a first antenna and a second antenna that are disposed on the insulating seat, and two feeding points electrically coupled to the first antenna and the second antenna. The first antenna includes a first body portion and a plurality of first extending portions connected to the first body portion. Each of the plurality of first extending portions is non-parallel to the first body portion. The second antenna includes a second body portion and a plurality of second extending portions connected to the second body portion. The second body portion is spaced apart from the first body portion. Each of the plurality of second extending portions is non-parallel to the second body portion. The second extending portions and the first extending portions are spaced apart from each other and jointly generate a capacitance effect.

Abstract: A wireless communication device includes an electronic assembly and a rear cover fastened on the electronic assembly. A groove is recessed from an outer edge of a surrounding side plate of the rear cover. An antenna structure of the rear structure includes a dual-frequency antenna at least partially arranged on the surrounding side plate and arranged adjacent to the groove, a low-frequency selector and a high-frequency selector both connected to the dual-frequency antenna, and a switch connected between the high-frequency selector and the dual-frequency antenna. Each of the low-frequency selector and the high-frequency selector is configured to change a center frequency of the dual-frequency antenna by impedance matching. When the dual-frequency antenna is in a low-frequency mode, the switch is configured to open the connection between the high-frequency selector and the dual-frequency antenna for obstructing a parasitic capacitance effect generated from the high-frequency selector.
