Description
[technical field]
The utility model belongs to communication technique field, more particularly to a kind of metal Coupling antenna structure.
[background technique]
For modern cell phones terminal antenna mostly based on built-in antenna, built-in antenna again can be by surrounding metal electronic component
Interference.For metal fuselage, method commonly used in the trade is that the antenna of FPC LDS material is made on antenna holder, is then put
Signal radiation is carried out in interior of mobile phone, or using metal cutting a part as antenna body.Disadvantage is done so it is also obvious that gold
Belonging to rear shell has the effect of shielding signal, leads to that antenna efficiency is poor, directionality is bad；If antenna body cut off,
It is affected when will affect complete machine appearance, and holding state.
[utility model content]
The main purpose of the utility model is to provide a kind of metal Coupling antenna structures, and metal rear shell ontology is participated in spoke
It penetrates, allows antenna to couple resonance required for generation with metal rear shell, improve antenna efficiency and radiation direction stability.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of metal Coupling antenna structure comprising gold
Belong to rear shell, the rectangular line of rabbet joint opened up from metal rear shell upper end side or lower end side level and is arranged described rectangular
Coupled antenna in the line of rabbet joint, the coupled antenna and the rectangular line of rabbet joint periphery are contactless, and feedback is provided on the coupled antenna
Electric, the end of the metal rear shell is provided with one in the region of the rectangular line of rabbet joint and switchs over the ground.
Further, the coupled antenna is rectangular slat shape.
Further, the coupled antenna is FPC antenna or LDS antenna.
Further, the width of the rectangular line of rabbet joint is 1.5-2.5mm.
Further, plastic cement is filled in the rectangular line of rabbet joint.
Further, the switch over the ground and cell phone mainboard grounding connection.
Further, the switch port over the ground, which is provided with, adjusts antenna resonance frequency inductively or capacitively.
Compared with prior art, a kind of beneficial effect of metal Coupling antenna structure of the utility model is: antenna frequencies
Return loss in range is nearly all in -5dB hereinafter, broader bandwidth；It is over the ground and electric by 5 different port RF1/RF2 of switch etc. over the ground
Sense or capacitor can switch different frequency, and low frequency bandwidth can be switched to 960mhz from 700mhz, and medium-high frequency can be from
1710mhz is switched to 2690mhz, greatly improves the passive index such as bandwidth, radiation efficiency of antenna, due to FPC antenna or
Person LDS antenna can reduce influence when holding at the back side of metal rear shell in this way；Utilize metal rear shell and FPC or LDS days
The design scheme of line coupling, had not only improved the signal radiation of mobile phone, but also do not influence complete machine appearance, and do not pollute, and assembling is simple
And other effects.
[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:
100 metal Coupling antenna structures；1 metal rear shell；The 2 rectangular lines of rabbet joint；3 coupled antennas；4 feeding points；5 switch over the ground.
[specific embodiment]
Embodiment:
Please refer to Fig. 1-Fig. 2, the present embodiment is metal Coupling antenna structure 100 comprising metal rear shell 1, after metal
The rectangular line of rabbet joint 2 that 1 upper end side of shell or lower end side level open up and the coupled antenna 3 being arranged in the rectangular line of rabbet joint 2, coupling
It closes antenna 3 and rectangular 2 periphery of the line of rabbet joint is contactless, feeding point 4 is provided on coupled antenna 3, the end of metal rear shell 1 is close to rectangular
Switch 5 over the ground are provided in the region of the line of rabbet joint 2, over the ground switch 5 and cell phone mainboard grounding connection, 5 port of switch is arranged over the ground
Have inductively or capacitively, to adjust the frequency point of antenna resonance, to widen the frequency range of complete machine antenna.
Coupled antenna 3 is rectangular slat shape, and the coupled antenna 3 is FPC antenna or LDS antenna, by FPC antenna or
The coupling of LDS antenna and the rectangular line of rabbet joint 2 of metal, improves the signal radiation of antenna.The length master of FPC antenna or LDS antenna
High-frequency resonant is controlled, therefore, the entire length of coupled antenna 3 can be adjusted flexibly according to high frequency radiation demand.The rectangular line of rabbet joint 2
Depth mainly control low-frequency resonant, its depth can be adjusted flexibly according to low frequency radiation demand.The width of the rectangular line of rabbet joint 2 is 1.5-
2.5mm is filled with plastic cement in the rectangular line of rabbet joint 2 in order to not influence the overall appearance of mobile phone.
Metal rear shell 1 with FPC perhaps LDS antenna couples when FPC or LDS length, width etc. all can be to complete machine day
The resonance of line has an impact, and therefore, should increase coupling area as far as possible in design, improve antenna radiation efficiency.
Fig. 2 is the present embodiment antenna passive return loss simulation result diagram, from figure 2 it can be seen that antenna frequencies range
Interior return loss is nearly all in -5dB hereinafter, broader bandwidth；By 5 different port RF1/RF2 of switch etc. over the ground over the ground and inductance or
Person's capacitor can switch different frequency, and low frequency bandwidth can be switched to 960mhz from 700mhz, and medium-high frequency can be cut from 1710mhz
2690mhz is changed to, the passive index such as bandwidth, radiation efficiency of antenna is greatly improved, due to FPC antenna or LDS antenna
At the back side of metal rear shell, influence when holding can be reduced in this way；It is coupled using metal rear shell with FPC LDS antenna
Design scheme had not only improved the signal radiation of mobile phone, but also did not influenced complete machine appearance, and do not pollute, and assembling is simple and other effects.
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.
