It is understandable to enable the above-mentioned purpose, feature and advantageous effect of the utility model to become apparent, below in conjunction with the accompanying drawings
Specific embodiment of the utility model is described in detail.
First embodiment
With reference to figure 1 and Fig. 2, Fig. 1 and Fig. 2 are the vertical views of antenna assembly, and Fig. 2 simplifies aerial coil 12
Preferably to illustrate.In first embodiment, antenna assembly includes mainly metallic plate 10 and aerial coil 12.The antenna assembly can be with
It is the antenna assembly of NFC antenna device, RFID antenna device or other appropriate types.
The material of the metallic plate 10 can be various metal materials appropriate, such as copper.Envelope is offered on the metallic plate 10
The profile of the through-hole 11 namely the through-hole 11 that close is closed, and without open opening or slit.It can in the through-hole 11
To be filled with dielectric material, or it can also be hollow out.Furthermore, the through-hole 11 may include center 110 and
Multiple (such as the 3) marginal zones 111 being connected to center 110.Wherein, multiple marginal zones 111 are all stretched out from center 110.
In other words, multiple marginal zones 111 converge at center 110.
As a unrestricted example, each vertex of the through-hole 11 in Fig. 1 connects the profile to be formed (referring to Fig. 2
In dotted line frame) shape be triangle.In other instances, each vertex of through-hole 11 connects the profile to be formed and can also be
Other shapes, including but not limited to rectangle, circle, ellipse, polygon (such as trapezoidal, pentagon etc.), irregular shape (example
Such as cloud shape).Metal component can be provided in center 110, but the metal component is not connect with the edge of center 110,
Namely has between metal component and the edge of center 110 and be isolated.It can be filled out between metal component and the edge of center 110
Filled with dielectric material, such as ceramics, plastics, paint etc..
As a unrestricted example, 111 shape of marginal zone in Fig. 2 is irregular figure, and which includes one
A or multiple bending sections, namely be bent to form similar to snakelike shape by one or many.In other instances, marginal zone
111 can also be other shapes, including but not limited to L-shaped, V-arrangement, N shapes, M shapes, W-shaped, triangle, ellipse, polygon, do not advise
The then combination of shape or these shapes.The profile of marginal zone 111 can be smooth, it is possible to have burr, such as integrally
In tree-shaped.The width of marginal zone 111 can be constant, can also be to become narrow gradually from center 110 or gradually become outward
Width, either first broaden to narrow again or first narrow broadens or other situations appropriate again.The shape of center 110 can be with
It is triangle, rectangle, circle, ellipse, polygon, irregular shape or other proper shapes.
Aerial coil 12 can be formed by multiturn conducting wire coiling, and cover at least part namely antenna of through-hole 11
The wiring path of coil 12 passes through through-hole 11.Wherein, aerial coil 12 covers the wire spacing of the part of through-hole 11 more than remaining
Partial wire spacing, that is, the wire spacing that aerial coil 12 covers the part of through-hole 11 is more than the portion for not covering through-hole 11
The wire spacing divided.Using such set-up mode, in the part aerial coil 12 for covering through-hole 11, each conducting wire will to the greatest extent may be used
It is dispersed at each position of through-hole 11 to energy, no matter which direction external electromagnetic field comes from relative to the antenna assembly, all
Have at least one conducting wire and be in preferably position relatively, to preferable sensitivity (for example, the distribution of magnetic flux is more
It is advantageous and reasonable).In turn, entire antenna assembly also correspondingly has preferable performance.
In addition, being covered in through-hole 11 in the aerial coil 12 of exterior domain, wire spacing is the smaller the better, to reduce occupancy
Area.

110 area is bigger, and the magnetic field energy of coupling is stronger, is also more conducive to the overall performance for improving antenna assembly.
Still further, aerial coil 12 covers at least one marginal zone 111 of through-hole 11, it is preferable that aerial coil
At least two marginal zone 111 of 12 covering through-holes 11.Since the wire spacing that aerial coil 12 covers the part of through-hole 11 is larger,
Therefore when covering one or two above marginal zones 111, the distributing position of conducting wire will more disperse, to occupy as much as possible
Various positions in through-hole 11, as much as possible so that wherein one or more conducting wire is in the more excellent position under present case, from
And be conducive to improve the performance of entire antenna assembly.
Preferably, in aerial coil 12, the width for being covered in the conducting wire on through-hole 11 compares the conductor width in other regions
It is wider.Specifically, the width for the conducting wire being covered on through-hole 11 is more wider than the width for being covered in the conducting wire on metallic plate 10.Compared with
Wide conducting wire makes the Q value highers of antenna assembly, is conducive to improve antenna performance；And wider conductor resistance is relatively low, on an equal basis
Under the conditions of electric current bigger, be conducive to improve antenna performance.The width for being covered in the conducting wire on metallic plate 10 is smaller, can reduce face
Long-pending occupancy.
Preferably, in the part of the covering of aerial coil 12 center 110, conducting wire is situated so as to cabling along straight line.Except this
In addition, the conducting wire of other parts could be provided as various figures appropriate, such as could be provided as arc, compared to rectangle, make
Cabling it is shorter, be conducive to reduce occupy area.
With reference to figure 2, Fig. 3 and Fig. 4, when external equipment (such as card reader) and antenna assembly couple, the antenna of external equipment
15 can be positioned near metallic plate 10, to be coupled with aerial coil 12.Antenna 15 is different relative to the position of metallic plate 10,
It can so that the inductive energy induced in aerial coil 12 is different.
In addition, aerial coil 12 is different relative to the position of through-hole 11, the inductive energy of aerial coil 12 can be also influenced.Tool
For body, the distance D (referring to Fig. 2) on the bottom edge of the profile of the top margin of the open area of aerial coil 12 apart from through-hole 11 can influence
The inductive energy of aerial coil 12.Different numerical value and antenna 15 difference relative to metallic plate 10 of the applicant for distance D
