Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: what a kind of full frequency band suitable for small headroom covered
Mobile communication terminal antenna, including shell 1, the shell 1 include upper metal frame 2, lower metal frame 3, antenna minor matters
11 and USB model 12, in 1 side of shell, the lower metal frame 3 is arranged in institute for the setting of upper metal frame 2
Shell 1 is stated far from 2 side of upper metal frame, the USB model 12 is mounted on the shell 1 close to the lower metal
Among 3 side of frame, the antenna minor matters 11 are arranged in the shell 1 close to 12 side of USB model.
Specifically, the antenna minor matters 11 are connect by feed placement 101 with the shell 1, feed placement 101 can be used
Carry out feed-in current signal.
Specifically, the antenna minor matters 11 are connected with link position 105, the connection position by first time position 102
105 are set to connect with the lower metal frame 3, by link position 105 can allow current signal antenna minor matters 11 with
It is transmitted between lower metal frame 3.
Specifically, 12 two sides of USB model are provided with second time position 103 to the shell 1 and third goes back to status
104 are set, second time position 103, the third are returned position 104 and are connect with the lower metal frame 3, and second time
Position 103 and third return the adjustable inductance value of position 104 to realize frequency shift (FS).
First time position 102 has accessed the electronic device with radio frequency on-off, such as: switch, diode, the present embodiment
It is middle to be illustrated using switch, but other electronic devices with radio frequency on-off can also reach this programme purpose；Second time status
Set 103 and third return position 104 access lamped element such as: inductance, capacitor, resistance can be equivalent to the structure of lamped element such as
Interdigitation or U-typed structure etc., in the implementation case second time position 103 and third return position 104 using inductance into
Row explanation.
Working principle: current signal enters antenna minor matters 11 from 101 feed-in of feed placement, and antenna minor matters 11 itself produce
Raw high-frequency resonant realizes that 2500~2690MHz frequency coverage, current signal flow into lower metal frame 3 by antenna minor matters 11,
After divide two-way, current signal is generated compared with low-frequency resonant and its frequency multiplication resonance, under by the long-armed radiation of lower metal frame 3
The galianconism radiation of portion's metal edge frame 3 generates resonance and realizes 1710~1880MHz frequency coverage, is adjusted by second time position 103
Economize on electricity inductance value, which can be tuned, achieves 699~800MHz frequency coverage compared with low frequency resonance frequency shift, then passes through first go back to ground
The switched tuning that position 102 is accessed achieves 790~960MHz frequency coverage to control frequency shift (FS), finally realizes 699
~960MHz frequency coverage, can tune frequency multiplication resonance frequency shift by the third time adjusting of position 104 inductance value makes in fact
Existing 1850~2170MHz frequency coverage, then made by the switched tuning that first time position 102 accesses to control frequency shift (FS)
It realizes 2300~2400MHz frequency coverage, is finally reached covering LTE and often uses 699~960MHz of full frequency band, 1710~
The purpose of 2690MHz.
