First antenna device according to embodiments disclosed herein is changed from slot antenna (slot antenna) Antenna, and multiple band resonances are provided in send and receive wireless signal.In general, wall table of the slot antenna in waveguide There is slit on the surface in face, cylindrical conductor or flat conductive plate, and fed to the part with slit, with raw in slit At electric field.Therefore, slot antenna operation is the radiator for electric wave.Typical slot antenna has been used for handling single band Wireless signal, but it is not used for the treatment of the wireless signal of multiband.This is because the Antenna Impedance Matching in each frequency band exists About 50 Ω (ohm) are executed, and are thus difficult to carry out impedance matching in different frequency bands.

It is configured such that the first radiation of the resonance together with slit according to the antenna assembly of implementations described herein Body is connected to the component of limitation (or restriction) slit, in multiple band resonances.Next, this will be retouched in greater detail with reference to the attached drawings It states.

Fig. 5 is the concept map of the first antenna device of an illustrative embodiments according to the present invention.Fig. 6 is to show figure The figure of the voltage standing wave ratio (VSWR) of antenna assembly shown in 5.Fig. 5 is the concept map for showing the structure of antenna assembly.It will reason Solution, when antenna assembly is actually mounted in mobile terminal, the shape or position for constituting each component of antenna assembly can be with Change.Therefore, the shape of antenna assembly shown in Fig. 5 and the shape of antenna assembly shown in Fig. 4 or Fig. 9 are slightly different.

Carried out on the entire main body of terminal by the radiation of wireless signal that antenna carries out, but mainly in radiator or It is carried out in slit.Therefore, it in order to explain, will hereafter be configured to radiate wireless signal with specific frequency in radiator or slit It is illustrated under assuming that.

As shown in figure 5, first antenna device ANT1 may include first component 310, second component 320, feed element 330 And first radiator 340.First antenna device ANT1 may further include the second radiator 350.With dotted line mark in Fig. 5 The part exemplary current of note along each component flowing.

First component 310 and second component 320 can be set to conductive member.First component 310 and second component 320 limit Make the slit S of (restriction) antenna assembly.That is, the space between first component 310 and second component 320 is slit S.Here, In order to briefly explain, the opening portion of slit S is referred to as opening 313, and due to the company of first component 310 and second component 320 It connects the closure to be formed and is referred to as interconnecting piece 315.

The length of slit S can be formed by the feed method of antenna, the dielectric dielectric constant for constituting antenna, increase Capacitor in feed element 330 etc. and change.Moreover, antenna assembly can be bent at its specific part with slit S or Person has smaller size in such a way that curved structure (Meander structure) is formed.

Slit S has one side opening and the other side by company that first component 310 and second component 320 are connected to each other The shape that socket part 315 is closed.That is, antenna assembly according to the present invention has the slit of a side opening.It is closed with two sides are used The slot antenna of slit compare, such antenna can be configured to humorous in low-frequency band using shorter slit due to mirror effect Vibration.That is, about half (1/2) of the slit for the slot antenna being closed with two sides can be used in the slot antenna of a side opening The slit of length is in same frequency band resonance.

Consider antenna efficiency, needs slit S that there is at least 0.003 λ times of width.When the increase of the width of slit S is more, Antenna assembly can be operated in lower band.

For the slot antenna that two sides are closed, in order to radiate the electric wave of first band, slit, which has, corresponds to wavelength λ/2 length, the length correspond to first band centre frequency f1.On the other hand, the slot antenna of a side opening is narrow Sewer has the length of λ/4 of the wavelength corresponding to centre frequency.In other words, the slot antenna of a side opening is by using shorter Slit can radiate the electric wave of the wireless signal corresponding to low-frequency band.

According to the present invention, the first radiator 340 is connected to a component of limitation slit S, in first band and second Frequency band resonance together with slit.This will lead to the length for further decreasing slit S.

Second band indicates frequency band more higher than first band.

For example, the slit of the slot antenna of one side opening has 45mm when the centre frequency of first band is 850MHz To the length of 50mm, which corresponds to λ/4 of the wavelength of centre frequency.But antenna assembly according to the present invention has the One radiator 340, and therefore can use about 40mm long (that is, the length with 0.15 λ of the wavelength corresponding to centre frequency) Slit sufficiently show antenna efficiency.In this way, since antenna assembly according to the present invention can be with short length Slit show sufficient antenna efficiency, so when antenna assembly is mounted in mobile terminal, it can be ensured that be used for other portions The installation space of part.This can be such that the size of mobile terminal reduces.

First component 310 and second component 320 can be formed by conductive any material.In present embodiment In, first component 310 be arranged to ground connection (ground) flexible printed circuit board, and second component 320 by It is set as the frame of bearing terminal inner.First component 310 and second component 320 can be electrically connected to each other.As shown in Figure 10, One component 310 can be used screw and be connected to second component 320.

First component 310 and second component 320 are the conductive members being arranged in terminal body, and can be set to have There is the conductive member of ground connection, for example, flexible printed circuit board, printed circuit board or metal framework.

Feed element 330 is fed to slot antenna, allows antenna assembly in specific frequency resonance.More specifically, feedback Electric unit 330 can be set such that one end is connectable to a component of limitation slit, to generate electricity in slit S ?.

According to feed method, feed element 330 be can connect to all components or at least partly component.

According to direct feed method, the feed element 330 extended from coaxial cable 252 (referring to fig. 4) can be across slit S Another component is extended to from a component.That is, one end of feed element 330 may be coupled to one according to direct feed method A component, and its other end can extend up to another component, to be connected to another component.

According to couple feed method, one end of feed element 330 may be coupled to a component, and its other end can be with It is separated with another component.

Feed element 330 can be located at the position that interconnecting piece 315 separates preset distance, that is, due to feed element 330, the impedance of the centre frequency of first band is about at the position of 50 Ω.Moreover, feed element 330 may include that setting is useful In the capacitor of impedance matching and the vent diverter (shunt element) of inductor.The adjustable resistance value of vent diverter, should Resistance value is the real part of impedance.For example, inductor increases resistance, and capacitor reduces resistance, enables to as impedance Matching is tuned.Vent diverter can be set to the lumped constant element (lumped at one end of feed element 330 constant element)。

Each of loop 391 and loop 392 may include feed element and matching unit.Feed element can be with It is arranged by the combination of balanced-unbalanced transformer (balun), shift unit, distributor, damper, amplifier etc..Matching is single Member can be implemented as series element or vent diverter.When being embodied as series element, the reactance of the imaginary part as impedance can change Become.As an example, inductor can increase reactance, and capacitor can reduce reactance, to change the resistance of special frequency band It is anti-.On the other hand, when being embodied as vent diverter, the resistance of the real part as impedance be can change.As an example, electric Sensor can increase resistance, and capacitor can reduce resistance, to change the impedance of special frequency band.

Mobile communication terminal can be used wireless communication and be communicated with wireless base station.For example, cellular phone can be used The cellular telephone band of 850MHz, 900MHz, 1800MHz and 1900MHz are (for example, global system for mobile communications (GSM) or GSM Cellular telephone band) it is communicated.Moreover, mobile terminal can for wideband code division multiple access (WCDMA) service from The frequency band of 1.92GHz to 2.17GHz is communicated.In addition, mobile terminal can be in the B13 or B17 for being used for long term evolution (LTE) The frequency band of the slave 704MHz to 960MHz of communication service is communicated.

Especially, it should be allowed first antenna device ANT1 executes communication in those wireless communication frequencies.Therefore, according to this The antenna assembly of the embodiment of invention can further use resonance frequency in high frequency band spread bandwidth.

Second radiator 350 can be separated from feed element 330.In other words, the side of the second radiator 350 can electricity It is connected to feed element 330.Second radiator 350 is provided in the third band resonance of neighbouring second band.For example, when the For one radiator 340 in first band and second band when the resonance together with slit, the second radiator 350 can have corresponding length Degree, in third band resonance.Therefore, the high frequency band of the frequency band of first antenna device ANT1 can be from the center of second band frequency Rate extends up to the centre frequency of third frequency band.

As shown in fig. 6, the centre frequency of third frequency band can be when the centre frequency of second band is 1.7GHz 2.1GHz.On the other hand, when the centre frequency of second band is 2.1GHz, the centre frequency of third frequency band be can be 1.7GHz.Second radiator, 350 adjustable length, to radiate wireless signal in centre frequency.Moreover, the length or width of slit It can change to correspond to the length of radiator.When the length of radiator increases, antenna assembly can be operated in lower band. Moreover, antenna assembly can be operated in lower band when the width of slit or length increase.

First radiator 340 may include：First part 341, being at least partly parallel to for the first part 341 are narrow Seam；And second part 342, the second part 342 at least partly intersect with slit.The change of the length of first part 341 Change the displacement of the centre frequency f2 of the displacement and second band that will affect the centre frequency f1 of first band, and second part The variation of 342 length will affect the centre frequency displacement of first band.

This of second radiator 350 is at least partly disposed parallel to feed element 330, this can permit the second radiation Body 350 has shorter length.The capacitive coupling of this origin self feeding unit 330 causes.Capacitive coupling can cause antenna The increase of capacitive reactance.When capacitor value increases, it is inversely proportional by the input impedance and frequency of capacitor.It therefore reduces resonance frequency. The reduction of resonance frequency indicates that antenna assembly includes capacitive coupling, and therefore can have shorter length, compared with low frequency Band operation.That is, antenna assembly can be in relatively narrow space in low frequency ribbon gymnastics if antenna assembly includes capacitive coupling component Make.
