Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Antenna for terminal units such as current panel computers cannot realize the problem that full frequency band covers, and this utility model carries
Supply the design of a kind of LTE all frequency bands antenna.
Refer to shown in Fig. 1～Fig. 4, LTE all frequency bands antenna described in the utility model, it is mainly used in panel computer.
Mainboard 10 is installed in panel computer, is provided with a clearance zone 11 in one end of mainboard 10, corresponding in this clearance zone 11
Be provided with the support 20 that a rectangle backing material plate is made, wherein said support 20 be by dielectric constant be 4.3, tangent angle loss be
The FR4 backing material plate of 0.025 is made.
In the present embodiment, mainboard 10 size uses the size of 9.7 the most conventional inch flat panel computers: 150 × 240mm2。
Having a size in the top of mainboard 10 is 16 × 150mm2Clearance zone 11, antenna is placed on clearance zone 11, the phase pair
Should a size of 90 × 16 × 3.6mm3FR4 (dielectric constant 4.3 and tangent angle loss 0.025) support on, antenna size is 57
×16×3.6mm3。
The support 20 that FR4 backing material plate is made, includes front 21, the back side 22, leading flank 23, trailing flank 24 and left and right two
Side, and support 20 are provided with loudspeaker 25.
The front 21 of its medium-height trestle 20 is printed with antenna body 211 and couples the first parasitic sky producing low frequency with body
Line 212, described first passive antenna 212 includes the first branch 2121 and the second branch 2122.The loudspeaker being provided with in support 20
Between 25 and antenna body 211 spacing be 6mm.
The leading flank 23 of support 20 is printed with the distributing point 231 connected as one with antenna body 211 and with described
The parasitism that one passive antenna 212 connects as one goes back to place 232, and described distributing point 231 and parasitic returning are formed between place 232
There is gap.
The 4th branch 241, quintafurcation the 242, the 6th branch 243 and the 7th branch it is printed with on the trailing flank 24 of support 20
244；Described 4th branch 241 connects as one with antenna body 211；
The back side 22 of support 20 is printed with the second passive antenna 221 and the 3rd branch 222.Described second passive antenna 221
For improving the high-frequency resonant of antenna body 211；Quintafurcation 242 and the first branch are passed through in described 3rd branch 222 one end
2121 connect, and the other end and the 6th branch 243 connect, and the first passive antenna 212, quintafurcation the 242, the 3rd branch 222 and
6th branch 243 connects as one；It is formed with gap between described 3rd branch 243 of branch the 222, the 6th and the 4th branch 241
30。
Wherein, antenna body 211 is fully wrapped around in the first passive antenna 212, and described antenna body 211, first is parasitic
Antenna the 212, second passive antenna 221 constitute with the monopole antenna that couples.
As shown in Figure 5,6, Fig. 5 is the simulation result after having done corresponding coupling, it is achieved that S11 value is at 693MHz-
3800MHz is both less than-5dB；The antenna-matching circuit figure that Fig. 6 is done by the design.
As it is shown in fig. 7, after removing back the second passive antenna, near 2GHz, return loss is deteriorated, and high frequency end floats simultaneously, because of
This back the second passive antenna effectively improves the resonance of HFS.
As shown in Figure 8, all there is impact on antenna resonance at all band in the distance between loudspeaker and antenna body, if removing
Loudspeaker, then can find that low frequency narrows, and HFS floats, i.e. the existence of loudspeaker has been also involved in the generation of resonance.
Owing to, in this programme, the size in coupling gap is very big for antenna resonance impact, as it is shown in figure 9, when changing feed
When point and the parasitic gap size returned between place, gap is the least, and the return loss near 2170MHz is the most shallow, and 3GHz part is humorous
Shake and all float.
In this programme, the motherboard size of panel computer is 150 × 240mm2, in order to verify that this programme can be fitted the most simultaneously
For smaller size of panel computer, then simulate the small-size main board impact on antenna, as shown in Figure 10, along with mainboard
Size reduces, and low frequency bandwidth narrows, and 1.4GHz-2GHz return loss deepens, and 2.6GHz shoals simultaneously.
Owing to resonance in this programme is mainly obtained by unipole antenna and right side parasitic couplings, therefore between them
The size in gap determines the most performance of antenna, as shown in figure 11, when gap is decreased or increased on the basis of original state
Time, the return loss of 1.4GHz-2.17GHz all rises and shoals, it was demonstrated that size variation 9. makes antenna resonance change very sensitive.
In order to see the parasitic impact for antenna performance, remove the first passive antenna, obtain Figure 12, it can be seen that go
After falling the first passive antenna, low frequency is wholly absent, and high frequency yet suffers from, and illustrates that the first passive antenna around unipole antenna passes through
Suitably slot-coupled, makes antenna resonance go out the low frequency of 690MHz-960MHz.
In sum, the LTE all frequency bands antenna that this utility model provides, antenna cabling is added two parasitisms and constitutes by one pole,
The antenna adding parasitism from general one pole is different, its first passive antenna (right side is parasitic) fully wrapped around antenna body, leads to body
Overcoupling creates low frequency, and antenna back adds the second passive antenna improving high frequency.This programme not only covers often
2G/3G/4G frequency range, and contain Band 11 and Band 21, i.e. 1400-1500MHz part, and Band 22/Band
42/Band 43, i.e. 3400-3600MHz/3600-3800MHz part, covers all of Band of LTE with this, it is achieved that S11
Value is both less than-5dB at 693MHz-3800MHz.And in common several flat board sizes, performance all meets requirement.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
