Specific embodiment
Fig. 1 is please referred to, better embodiment of the invention discloses a kind of antenna structure 100, is applied to mobile phone, a number
In the wireless communication devices such as word assistant 200.
The wireless communication device 200 includes mainboard 210 and housing 220.The antenna structure 100 is set to the mainboard 210
On, which covers on mainboard 210 to protect the antenna structure 100.One end setting width about 3mm's of the mainboard 210
Clearance zone 230, the clearance zone 230 refer on mainboard 210 without region existing for conductor, to prevent in external environment electronic building brick such as
Battery, vibrator, loudspeaker, charge coupling device（Charge Coupled Device, CCD）Deng to wireless communication device 200
Antenna structure 100 generates interference, its operating frequency offset or radiation efficiency is caused to be lower.
Also referring to Fig. 2, which includes the first radiator 20 and the second radiator 30.First radiation
20 and second radiator 30 of body may be contained within the clearance zone 230 of mainboard 210, so that the antenna structure 100 obtains good spoke
Penetrate performance.
First radiator 20 include feed side 21, the first ground terminal 22, the first extension 23, the second extension 24 and
Third extension 25.21 and first ground terminal 22 of feed side is sheet body, and the two is arranged in parallel and is connected by an adapter section 211
It connects, so that the feed side 21,211 and first ground terminal 22 of adapter section form a structure of falling c-type.The feed side 21 electrically connects
The side of the mainboard 210 is connected to, with for the 20 feed-in electric current of the first radiator.First ground terminal 22 is electrical with the mainboard 210
Connection, ground connection is provided for first radiator 20, so as to flow into the electric current forming circuit of first radiator 20.First extension
Section 23 is electrically connected at the feed side 21, and first extension 23 includes the first plane 231 and second being mutually connected vertically
Plane 232.First plane 231 and 21 vertical connection of feed side, second plane 232 are arranged in parallel with feed side 21.This
Two extensions 24 are coplanar with first plane 231, and one first slit 241 is formed between the first plane 231.The third
Extension 25 and first plane 231 be coplanar with and with 24 vertical connection of the second extension.The third extension 25 along with
The parallel direction of first extension 23 extends to cross first extension 23.First extension 23 and the third extension
One second slit 251 is formed between 25, which connects with the first slit 241.In the present embodiment, this first
The length of extension 23 is 28.5mm, and the length of third extension 25 is 56mm.The width of first extension 23 be more than this
For the width of three extensions 25 so as to preferably feed-in electric current, the width of second slit 251 is 0.5mm.
Second radiator 30 includes the second ground terminal 31 and the linkage section 32 being electrically connected with second ground terminal 31.It should
Second ground terminal 31 is a sheet body, is coplanar with the first ground terminal 22 and is electrically connected at mainboard 210 far from the first ground connection
The side at end 22, to provide ground connection for second radiator 30.The linkage section 32 be connected to second ground terminal 31 and towards this
First ground terminal 22 extends.The linkage section 32 be parallel to the third extension 25 of first radiator 20 and with third extension 25
Setting spaced apart, so that flowing through on the current coupling to the second radiator 30 of the third extension 25.In this implementation
In mode, the length of the linkage section 32 is 22mm.
Also referring to Fig. 3, the operation principle of the antenna structure 100 in the present embodiment is further illustrated below：First when
After 21 feed-in electric current of feed side, there is electric current to flow through on first radiator 20, electric current flows through the first extension 23, the second extension
24 and third extension 25 and pass through adapter section 211 flow to the first ground terminal 22 formed a current loop so that this day knot
Wireless signal of the transmitting-receiving of structure 100 with the first centre frequency.Manufacturing and designing the stage, by adjusting first extension 23, the
Size and the first slit 241, the size of the second slit 251 of two extensions 24 and third extension 25 so that the antenna structure
100 have preferable effect when receiving and dispatching the wireless signal that the first bandwidth is 824MHZ~960MHZ.Meanwhile third extension 25
On when thering is the electric current to flow through, since the spacing between the linkage section 32 and the third extension 25 meets pre-provisioning request so that
On the current coupling to the linkage section 32, electric current, which flows through the linkage section 32 and flow to the second ground terminal 31, forms a current loop,
So that wireless signal of the antenna structure 100 transmitting-receiving with second central frequency.Since third extension 25 can be with linkage section
32 generation couplings inspire new resonance mode jointly, so that frequency range of the antenna structure 100 in second central frequency
It is upper that there is wider bandwidth.Manufacturing and designing the stage, prolonging by adjusting the size and the linkage section 32 of the linkage section 32 with third
The spacing of long section 25 so that the antenna structure have when receiving and dispatching the wireless signal that the second bandwidth is 1710MHZ ~ 2170MHZ compared with
Good effect.In this way, the antenna structure 100 can receive and dispatch the wireless signal in multiple frequency ranges, and with wider bandwidth.
The antenna structure 100 of the present invention causes the first radiator by setting the first radiator 20, the second radiator 30
20 third extension 25 intercouples with the linkage section 32 of second radiator 30 to send out new resonance mode, so that
Antenna structure 100 can receive and dispatch the signal of multiple frequency ranges, and improve the bandwidth of antenna structure 100, can meet wireless communication
Requirement of the device 200 for multifrequency and broadband, enhances user experience.And due to the first radiator 20 and the second radiator 30
It is set to the side of mainboard 210, and the first plane 231 of 25 and first extension 23 of second extension 24 and third extension
It is coplanar with, so that the structure of the antenna structure 100 is more compact to be suitable for the wireless communication with smaller clearance zone
Device saves the inner space of wireless communication device, improves the flexibility of wireless communication device interior design.
