Embodiment 1

[0058] Such as figure 1 As shown, a near-field antenna device includes a metal plate 1A and an unbalanced antenna part 2, the metal plate is provided with a semi-closed slot 1A1, and the unbalanced antenna part is arranged directly above the semi-closed slot 1A1 , the unbalanced antenna component 2 includes a dielectric substrate layer 24 and an unbalanced antenna trace 21 attached to the dielectric substrate layer, and the unbalanced antenna trace is in the shape of a serpentine multi-bend. The serpentine multi-bending unbalanced antenna line is bent in multiple places and is orthogonally coupled with the semi-closed slot. Such as image 3 As shown, one end of the serpentine multi-bending unbalanced antenna wire is connected to the near-field antenna module 4 , and the other end is grounded. Such as figure 2 As shown, the unbalanced antenna line 21 in the shape of a serpentine multi-bend is orthogonal to the semi-closed slot 1A1 of the metal plate 1A, wherein the current ...

Embodiment 2

[0061] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 lies in the change of the unbalanced antenna routing form. The unbalanced antenna routing in this embodiment has a "匚" font structure, and the "匚" font structure is The upper and lower sides of the balanced antenna line 22 are perpendicular to the semi-closed gap of the metal plate 1A. The current 22i on the unbalanced antenna wire 22 of the "匚"-shaped structure is coupled with the current 3 generated by the semi-closed gap, so that the metal plate 1A has the near field communication capability.

[0062] Such as Figure 6 As shown, one end of the "匚"-shaped unbalanced antenna wiring 22 is connected to the near-field antenna 4 module, and the other end is grounded.

[0063] The rest of the unmentioned technical features of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0065] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the balanced antenna routing form is a "C" semi-circular shape, and the two sides of the unbalanced antenna routing 23 in the "C" semi-circular shape The curved edge is perpendicular to the semi-closed gap of the metal plate 1A. The current 23i on the unbalanced antenna wire 23 in the shape of the "C" semi-circular ring is coupled with the current 3 generated by the semi-closed gap, so that the metal plate 1A has near-field communication capability.

[0066] Such as Figure 8 As shown, one end of the unbalanced antenna wire 23 in the shape of a "C" semicircle is connected to the near-field antenna 4 module, and the other end is grounded.

[0067] The rest of the unmentioned technical features of this embodiment are the same as those of Embodiment 1.

Abstract

The invention provides a near field antenna apparatus and equipment thereof. The near field antenna apparatus comprises a metal plate and a non-balance antenna part, wherein a disconnecting structure is arranged on the metal plate; the non-balance antenna part is arranged just above the disconnecting structure; the non-balance antenna part comprises a dielectric base material layer and a non-balance antenna routing part which is attached to the dielectric base material layer; at least one side of the non-balance antenna routing part is in cross coupling with the disconnecting structure; and one end of the non-balance antenna routing part is connected with a near field antenna module while the other end of the non-balance antenna routing part is grounded. According to the scheme, the implementation way of the conventional power supply coil and a ferrite is abandoned; the way of the scheme is different from the way for realizing cross coupling on a metal slot by adopting a vortex coil conductor in the prior art; instead, the near field antenna apparatus adopts the non-balance antenna for realizing slot coupling; the non-balance antenna of the type has no special shape requirement and is relatively high in flexibility; the near field antenna apparatus adopts a metal back cover for radiating the magnetic field; the design of the ferrite and the coil is not required, so that a lower cost is realized; and in addition, the metal back cover is utilized for realizing the slot coupling, so that the structural utilization rate is high.

Description

technical field [0001] The present invention relates to the field of near-field wireless communication, and more specifically, relates to a near-field antenna device and its equipment. Background technique [0002] In recent years, with the rapid development of consumer electronics products, especially the rapid growth of communication terminals such as smartphone terminals, tablet computers and tablet computers, products with all-metal structure, ultra-thin appearance, good touch and excellent user experience It is a necessary condition for becoming a leader in the consumer electronics industry. The traditional plastic casing has become a representative of cheap products, and the pursuit of higher profit all-metal casing product design has become the appeal of all terminal companies. However, the introduction of all-metal design has brought unprecedented challenges to antenna design. Especially for near-field antennas, it is easy to be shielded in an all-metal environment...
