A part of antenna entity is shared between same frequency range, it can be by adjusting the on-off shape of the control switch between each antenna part
State makes antenna length free switching between multiple states, cooperates adjustable adjustable match circuit, realizes antenna same
Moment only supports the frequency range needed, reduces requirement of the multifrequency antenna to day space of lines, realizes the miniaturization and intelligence of antenna
Change, reduces area and the environmental requirement of mobile terminal antenna.
Based on the structural schematic diagram of antenna shown in Fig. 3, present invention also provides the structures of another antenna shown in Fig. 4
Schematic diagram, as shown in figure 4, the antenna further includes that sheet metal 8 and metal are shorted needle on the basis of antenna structure shown in Fig. 3
7.Wherein,
One end of sheet metal 8 is connect with one end that metal is shorted needle 7, and metal is shorted the other end of needle 7 and prolonging for most latter end
It also is provided with extension antenna 2-n and metal for controlling most latter end between long antenna 2-n and is shorted to concatenate between the other end of needle
Switching circuit 3-n+1, wherein switching circuit 3-n+1 is connected to the ON-OFF control circuit 4 for control switch connecting and disconnecting of the circuit.
Wherein, there is a protective case on sheet metal 8, for so that sheet metal 8 and metal are shorted the top of needle 7 and mobile terminal
Frame or lower frame are connected.Wherein, the material of protective case can be silica gel.
Wherein, the length of sheet metal 8 is greater than or equal to the first preset threshold and is less than or equal to the second preset threshold；Metal
The length for being shorted needle 7 is greater than or equal to third predetermined threshold value.
Wherein, the first preset threshold can be 25 millimeters, can be 26 millimeters, can be 27 millimeters, can be 29 millimeters；
Second preset threshold can be 70 millimeters, can be 69 millimeters, be also possible to 68 millimeters etc..It should be noted that sheet metal 8
Length adjusts according to the actual situation, and length is longer, and frequency is lower.
Wherein, third predetermined threshold value can be 1.0 millimeters to 1.5 millimeters.It should be noted that metal is shorted the length of needle 7
To spend longer, the frequency of the frequency range part of above-mentioned Antenna Operation is lower, but in order to enable the shape of mobile terminal is more beautiful,
Therefore when third predetermined threshold value is 1.5 millimeters, user has been met for the demand of the shape of mobile terminal.
Wherein, sheet metal 8 is less than or equal to the 4th preset threshold at a distance from the upper side frame or lower frame of mobile terminal.Its
In, the 4th preset threshold can be 2 millimeters.
Antenna shown in Fig. 4 realizes the 700MHz working frequency range for generating and needing.It should be noted that applicant is by dividing
Analysis antenna current distribution learns that if only passing through sheet metal 8 and coupling with antenna, sheet metal 8 is upper with mobile terminal
The distance of frame or lower frame is how many, due to low frequency branch (the most extension antenna 2-n of latter end) electric current of sheet metal 8 and antenna
Always it is in the same direction, therefore cannot achieve low frequency branch length and effectively increase, to cannot achieve the 700MHz work for generating and needing
Make frequency range, and connect by one end in sheet metal 8 with one end that metal is shorted needle 7, metal is shorted one end and the low frequency point of needle 7
Zhi Xianglian realizes the 700MHz working frequency range for generating and needing so as to allow sheet metal 8 to couple with the low frequency branch of antenna；
When not needing to generate 700MHz working frequency range, only metal need to be shorted to the extraction of needle 7 or ON-OFF control circuit 4 disconnects switching circuit
3-n+1.
Fig. 5 is the schematic diagram of the application antenna and mobile terminal, wherein the length of the sheet metal 8 in the present embodiment is
60mm, sheet metal 8 are equal to 2 millimeters at a distance from the upper side frame or lower frame of mobile terminal, and metal is shorted one end and the low frequency of needle 7
Branch is connected, and the other end that metal is shorted needle 7 is connected with one end of sheet metal 8.
