Description
[technical field]
The utility model belongs to communication technique field, more particularly to a kind of antenna structure of all-metal shell mobile phone.
[background technique]
Raising with people to requirements such as cell phone appearance, quality, present antenna for mobile phone mostly use built-in antenna, pass through
Built-in antenna carries out mobile phone signal radiation.The common design method of antenna for mobile phone is at present: with metal materials such as FPC or LDS
It is designed to the antenna pattern of different frequency, antenna body is then fed into mobile phone signal source, so that mobile phone signal can lead to
Antenna body is crossed to be radiated.This antenna design method radiation effect in plastic fuselage is relatively good, but encounters all-metal machine
When body, since metal fuselage has signal shielding effect, mobile phone signal is difficult to radiate.
[utility model content]
The main purpose of the utility model is to provide a kind of antenna structures of all-metal shell mobile phone, by the metal of mobile phone
Rear shell ontology is radiated as antenna, to improve the signal radiation effect of all-metal shell mobile phone.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of antenna structure of all-metal shell mobile phone,
It includes all-metal rear shell ontology, and the top or lower part of the all-metal rear shell ontology are provided with a penetrating gap, institute
It states filled with plastic cement in gap, the all-metal rear shell ontology is separated into large-area metal plate and strip gold by the gap
Belong to item, be provided on the strip metal strip first over the ground switch and second switch over the ground, the strip metal strip is upper
A signal feed-in point and grounding point, the grounding point are provided between described first switchs over the ground and described second switchs over the ground
Ground connection is connect with cell phone mainboard.
Further, the all-metal rear shell ontology and cell phone mainboard are grounded.
Further, the width in the gap is more than or equal to 1.5mm.
Compared with prior art, a kind of beneficial effect of the antenna structure of all-metal shell mobile phone of the utility model is:
Return loss within the scope of antenna frequencies is nearly all in -5dB hereinafter, over the ground and inductance switches over, low frequency by switch different port
Bandwidth can be switched to 960mhz from 700mhz, and medium-high frequency can be switched to 2690mhz from 1710mhz, greatly improve day
The passive index such as bandwidth, the radiation efficiency of line；The cost of built-in antenna can be saved by making antenna using metal rear shell simultaneously, not had
Pollution, assembling is simple, saves human cost；It makees antenna using metal rear shell to be difficult to control antenna body size, to antenna resonance
It is affected, this programme is utilized switched tuning over the ground and adjusts its length, improves the stability and validity of antenna resonance.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the passive return loss simulation result diagram of the utility model embodiment；
Digital representation in figure:
The antenna structure of 100 all-metal shell mobile phones；1 metal rear shell ontology, 11 large-area metal plates, 12 strips gold
Belong to item；2 gaps；3 first switch over the ground；4 second switch over the ground；5 signal feed-in points；6 grounding points.
[specific embodiment]
Embodiment:
Fig. 1-Fig. 2 is please referred to, the present embodiment is the antenna structure 100 of all-metal shell mobile phone comprising all-metal rear shell
Ontology 1, the top or lower part of all-metal rear shell ontology 1 are provided with a penetrating gap 2, are filled with plastic cement in gap 2, entirely
Metal rear shell ontology 1 is separated into large-area metal plate 11 and strip metal strip 12, strip metal strip 12 by the gap 2
On be provided with the first switch 3 and the second switch 4 over the ground over the ground, the first switch 3 and second over the ground is located on strip metal strip 12
A signal feed-in point 5 and grounding point 6 are provided between switch 4 over the ground, grounding point 6 connect ground connection with cell phone mainboard.
All-metal rear shell ontology 1 and cell phone mainboard are grounded.
All-metal rear shell ontology 1 is cut off the strip metal strip 12 that isolation is formed and is used as antenna body, antenna sheet by gap 2
Body plastic cement is connect with large-area metal plate 11, and the width in gap 2 is more than or equal to 1.5mm, guarantees that aerial radiation effect is good.
By the way that the first switch 3 and the second switch 4 over the ground over the ground are arranged on strip metal strip 12, it is respectively intended to adjust low
Frequency and medium-high frequency antenna resonance, to increase the beamwidth of antenna.
Referring to figure 2., Fig. 2 is the present embodiment antenna passive return loss simulation result diagram, from figure 2 it can be seen that day
Return loss within the scope of line frequency is nearly all in -5dB hereinafter, over the ground and inductance switches over, low-frequency band by switch different port
Width can be switched to 960mhz from 700mhz, and medium-high frequency can be switched to 2690mhz from 1710mhz, greatly improve antenna
The passive index such as bandwidth, radiation efficiency；The cost of built-in antenna can be saved by making antenna using metal rear shell simultaneously, without dirt
Dye, assembling is simple, saves human cost；It makees antenna using metal rear shell to be difficult to control antenna body size, to antenna resonance shadow
Sound is larger, and this programme is utilized switched tuning over the ground and adjusts its length, improves the stability and validity of antenna resonance.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
