Detailed description will be provided to the embodiment of the present invention below.Although the present invention will combine some specific embodiments
It is illustrated and illustrates, but should be noted that the present invention is not merely confined to these embodiments.On the contrary, to the present invention
The modification of progress or equivalent replacement, are intended to be within the scope of the claims of the invention.
In addition, in order to better illustrate the present invention, numerous details is given in specific embodiment below.
It will be understood by those skilled in the art that without these details, the present invention can equally be implemented.It is right in other example
It is not described in detail in known structure and component, in order to highlight the purport of the present invention.
Carry out detailed description of the present invention exemplary embodiment now with reference to attached drawing.Fig. 1 is in one embodiment of the invention
Antenna assembly stereoscopic schematic diagram.Fig. 2 is the schematic top plan view of the antenna assembly in one embodiment of the invention.Fig. 3 is this hair
Diagrammatic cross-section of the antenna assembly at feed element in a bright embodiment
As shown in Figure 1, Figure 2 and shown in Fig. 3, the antenna assembly 10 of first embodiment of the invention includes the first resonant antenna 101
And second resonant antenna 102.
The first resonant antenna 101 is introduced first.First resonant antenna 101 is a non-closed cavity, including
Metal shell 1101 and sheet metal 1012, sheet metal 1012 surround to form non-closed cavity with metal shell 1101.At this
In embodiment, the shape of the first resonant antenna 101 is cuboid, it is contemplated that the first resonance day in other embodiments
Line 101 can also be other shapes.
Metal shell 1101 includes metal backing 10111 and metal edge frame 10112, and metal edge frame 10112 is carried on the back around metal
Plate 10111.Wherein, metal backing 10111 and metal edge frame 10112 are integrally formed, that is to say, that metal backing 10111 and gold
There is no gap between category frame 10112, without nonmetallic interval of the prior art yet.
In the present embodiment, sheet metal 1012 is rectangle, has the four edges being connected.Sheet metal in other embodiments
1012 can also use other shapes, such as diamond shape or trapezoidal.
At least one gap 1013 and at least one opening are formed between the periphery of sheet metal 1012 and metal edge frame 10112
Portion 1014, that is to say, that the first resonant antenna 101 is non-closed, so that when the first resonant antenna 101 passes through feed element
11 by direct feed or couple feed when, the first resonant antenna 101 can send out the signal of certain frequency.In the present invention, until
A few gap 1013 is formed between the periphery of sheet metal 1012 and metal edge frame 10112, without being formed at sheet metal
On the one hand 1012 first-class other positions, such setting ensure that the integrality of the metal shell of antenna assembly 10, and convenient for adding
Work, the another aspect position will not set other component, example in the side of metal backing 10111 opposite to each other because of in sheet metal 1012
Such as display device, and signal transmitting and receiving is had an impact.
Here direct feed refers to feed element 11 by being in direct contact with the first resonant antenna 101 and to the first resonance
Antenna 101 is fed, and couple feed refers to first resonance by way of being not directly contacted with the first resonant antenna 101 of feed element 11
Antenna 101 is fed.The present embodiment employs the mode of couple feed, as shown in FIG. 2 and 3, the first resonant antenna 101 it is interior
Portion sets circuit board 12, one end connection circuit board 12 of feed element 11, to obtain exciting current from circuit board 12.Feed element
11 other end connects the second resonant antenna 102, is not connected to the first resonant antenna 101, but encourages the first resonant antenna 101 in spy
Determine resonant frequency resonance.
The resonant frequency of first resonant antenna 101 is mainly determined by the length of non-closed cavity, width and height.Specifically
For, shape in the present embodiment has a long a, wide b and high c for the cavity 100 of cuboid, the first resonant antenna 101 it is humorous
Vibration frequency f1 meets the following formula：
M, n, p=0,1,2,3,4 ... (integers)
Wherein, v is the aerial speed of light.Same first resonant antenna 101 has multiple mode (mode), different
The combination of m, n, p represent different modalities, and different mode has corresponded to different resonant frequencies, i.e. the first resonant antenna 101 has
There are multiple working frequency range.Wherein, first mode has corresponded to the first working frequency range, and second mode has corresponded to the second working frequency range.
The resonant frequency of first resonant antenna 101 is also influenced by the length and quantity in gap 1013.Sheet metal
1012 periphery has four sides adjacent with the metal shell 1011, is open wherein being formed between metal shell 1011 on one side
Portion 1014 at least forms a bar shaped gap 10131 in excess-three side between adjacent localized metallic frame 10112 on one side.
As the quantity in bar shaped gap 10131 increases and total length increases, the resonant frequency of the first resonant antenna 101 reduces.Fig. 4 a-
4d is schematic top plan view when first antenna of the invention includes different bar shaped gaps.
As one of optional embodiment, as shown in fig. 4 a, a line of sheet metal 1012 and adjacent local metal edges
Frame 10112 forms a bar shaped gap 10131.The position in one bar shaped gap 10131 is not limited to the position shown in Fig. 4 a,
But the arbitrary a line of sheet metal 1012 except 1014 position of opening portion and adjacent local metal edge frame can be formed in
Between 10112.
As another optional embodiment, as shown in Figure 4 b, two sides that sheet metal 1012 is connected respectively with it is adjacent
The metal edge frame 10112 of part forms a bar shaped gap 10131, which connects.Between two bar shapeds
The position of gap 10131 is also not necessarily limited to the position shown in Fig. 4 b.
As another optional embodiment, as illustrated in fig. 4 c, its excess-three side of sheet metal 1012 respectively with adjacent part
A bar shaped gap 10131 is formed between metal edge frame 10112, which does not connect.
As another optional embodiment, as shown in figure 4d, its excess-three side of sheet metal 1012 respectively with adjacent part
A bar shaped gap 10131 is formed between metal edge frame 10112, three bar shaped gaps 10131 connect, i.e. three bar shaped gaps
10131 end to end connections are in a ring.
By above explanation as can be seen that by gap 1013 be set as 1012 periphery of sheet metal at least on one side with it is adjacent
Localized metallic frame 10112 between bar shaped gap 10131, on the one hand can ensure the whole installation of full metal jacket, it is another
Aspect is when needing to adjust the first 101 resonant frequency of resonant antenna, the quantity or length in adjustment bar shaped gap 10131, phase
For the set-up mode in other gaps, adjustment is more simple easy to process.
In the first embodiment of the present invention, 1013 set-up mode of gap as shown in figure 4d, i.e. the first resonance are employed
Antenna 101 includes an opening portion 1014 and the bar shaped gap 10131 of three connections.However can be seen that as described above,
Due to increasing and total length increases with the quantity in bar shaped gap 10131, the resonant frequency of the first resonant antenna 101 reduces,
The quantity and length in the length of the first resonant antenna 101 of design, width, height and matching design gap 1013 can be passed through
It spends that the first resonant antenna 101 is worked under specific frequency.
