Herein, signal line 20a, 20b extends from the coupling part of inductor L to the negative direction side in x-axis direction and positive direction side respectively.The coil axes Ax of inductor L extends to x-axis direction.That is, in high frequency signal transmission line 10, the direction that the direction of coil axes Ax extension and signal line 20a, 20b extend from the coupling part of inductor L is consistent.
Connector 100a, 100b are arranged on the surface of connecting portion 12b, 12c respectively, and are electrically connected with signal line 20a, 20b, inductor L and earthing conductor 22.The structure of connector 100a, 100b is identical, therefore, is described below for the structure of connector 100b.Fig. 5 is the stereoscopic figure of connector 100b and connecting portion 12c.Fig. 6 is the sectional structure chart of connector 100b.
As shown in Figures 5 and 6, connector 100b by connector body 102, outside terminal 104,106, center conductor 108 and external conductor 110 form.The rectangular plate of connector body 102 is linked with the shape of cylinder, is made up of insulating material such as resins.

Center conductor 108 is arranged on the center of the cylinder of connector body 102, and is connected with outside terminal 104.Center conductor 108 is the signal terminals inputing or outputing high-frequency signal.External conductor 110 is arranged at the inner peripheral surface of the cylinder of connector body 102, and is connected with outside terminal 106.External conductor 110 is the earth terminals keeping earthing potential.
The connector 100b with above structure is arranged on the surface of connecting portion 12c, and to make outside terminal 104 be connected with outside terminal 16b, outside terminal 106 is connected with terminal conductor 22c.Thus, signal line 20a, 20b and inductor L is electrically connected with center conductor 108.In addition, earthing conductor 22 is electrically connected with external conductor 110.
High frequency signal transmission line 10 uses by the mode of following explanation.Fig. 7 is the figure overlooking the electronic equipment 200 employing high frequency signal transmission line 10 from y-axis direction.Fig. 8 is the figure overlooking the electronic equipment 200 employing high frequency signal transmission line 10 from z-axis direction.
Electronic equipment 200 comprises high frequency signal transmission line 10, circuit substrate 202a, 202b, socket 204a, 204b, battery pack (metallic object) 206 and housing 210.
In high frequency signal transmission line 10, circuit substrate 202a, 202b, socket 204a, 204b and battery pack (metallic object) 206 are accommodated in by housing 210.Circuit substrate 202a is provided with the transtation mission circuit or receiving circuit that such as comprise antenna.Circuit substrate 202b is provided with such as power supply circuits.Battery pack 206 is such as Li-Ion rechargeable battery, has the structure that its surface is covered by metal cover board.Circuit substrate 202a, battery pack 206 and circuit substrate 202b arrange from the negative direction side direction positive direction side in x-axis direction according to this order.
Socket 204a, 204b are separately positioned on the interarea of the negative direction side in the z-axis direction of circuit substrate 202a, 202b.Socket 204a, 204b are connected with connector 100a, 100b respectively.Thus, via socket 204a, 204b, the center conductor 108 to connector 100a, 100b is applied to the high-frequency signal such as with 2GHz frequency carrying out between circuit substrate 202a, 202b transmitting.In addition, via circuit substrate 202a, 202b and socket 204a, 204b, the external conductor 110 of connector 100a, 100b is remained on earthing potential.Thus, high frequency signal transmission line 10 is connected electrically between circuit substrate 202a, 202b.

(manufacture method of high frequency signal transmission line)
Below, be described with reference to the manufacture method of Fig. 2 to high frequency signal transmission line 10.Below, be described for the situation making a high frequency signal transmission line 10, but make multiple high frequency signal transmission line 10 indeed through stacked and the large-scale dielectric sheet material of cutting simultaneously.
First, prepare dielectric sheet material 18a ~ 18c, the thermoplastic resin that this dielectric sheet material 18a ~ 18c is formed with Copper Foil by whole surface is formed.The surface of the Copper Foil of dielectric sheet material 18a ~ 18c is such as implemented for antirust zinc-plated next smoothingization.The thickness of Copper Foil is 10 μm ~ 20 μm.
Then, utilize photo-mask process, form outside terminal 16a, the 16b shown in Fig. 2 and earthing conductor 22 on the surface of dielectric sheet material 18a.Specifically, the Copper Foil of dielectric sheet material 18a prints its outside terminal 16a, 16b shown in shape with Fig. 2 and the identical resist of earthing conductor 22.Then, etch processes is implemented to Copper Foil, thus remove the Copper Foil of the part do not covered by resist.Then, resist is removed.Thus, outside terminal 16a, 16b as shown in Figure 2 and earthing conductor 22 is formed on the surface of dielectric sheet material 18a.
Then, utilize photo-mask process, form signal line 20a, 20b shown in Fig. 2 and linear conductor 40a ~ 40h on the surface of dielectric sheet material 18b.Utilize photo-mask process, form the linear conductor 42a ~ 42g shown in Fig. 2 on the surface of dielectric sheet material 18c.In addition, above-mentioned photo-mask process is identical with photo-mask process when forming outside terminal 16a, 16b and earthing conductor 22, and therefore the description thereof will be omitted.
Next, through hole is formed from the position illuminating laser beam of rear side to formation via hole conductor b1, b2, b11 of dielectric sheet material 18a ~ 18c ~ b17, b21 ~ b27.Afterwards, conductive paste is filled in the through hole being formed at dielectric sheet material 18a ~ 18c.
Next, dielectric sheet material 18a ~ 18c is stacked according to this order from the positive direction side in z-axis direction towards negative direction side.Then, from the positive direction side in z-axis direction and negative direction side, heat and pressure are applied to dielectric sheet material 18a ~ 18c, thus dielectric sheet material 18a ~ 18c is softened and carries out crimping/integration, and, the conductive paste be filled in through hole is cured, to form via hole conductor b1, b2, the b11 shown in Fig. 2 ~ b17, b21 ~ b27.In addition, via hole conductor b1, b2, b11 ~ b17, b21 ~ b27 both can form through hole after making dielectric sheet material 18a ~ 18c integration, be filled in through hole by conductive paste and formed, and also can be formed by forming plated film.In addition, for via hole conductor b1, b2, b11 ~ b17, b21 ~ b27, not necessarily fill up through hole completely with conductor, such as, form via hole conductor by only forming conductor along through hole inner peripheral surface.
Then, by coating resin (resist) thickener, thus protective layer 14 is formed on dielectric sheet material 18a.
Finally, mounted connector 100a, 100b on the surface of connecting portion 12b, 12c.Thus, the high frequency signal transmission line 10 shown in Fig. 1 is obtained.
(effect)
According to the high frequency signal transmission line 10 with above structure, while suppressing the inductance value of inductor L to decline, the slimming of high frequency signal transmission line 10 can be realized.More specifically, in high frequency signal transmission line 10, the coil axes Ax of inductor L extends along the x-axis direction, almost parallel with the interarea of earthing conductor 22.Therefore, the magnetic flux that inductor L produces mainly towards x-axis direction, and is difficult to run through earthing conductor 22.Thus, even if in order to realize the slimming of high frequency signal transmission line 10 and the distance between reduced inductance device L and earthing conductor 22, the eddy current produced in earthing conductor 22 is also difficult to increase.Consequently, in high frequency signal transmission line 10, while suppressing the inductance value of inductor L to decline, the slimming of high frequency signal transmission line 10 can be realized.Such high frequency signal transmission line 10 is specially adapted to the high frequency signal transmission line of flat cable type.
In addition, according to high frequency signal transmission line 10, the deviation of the inductance value of inductor L can be reduced.More specifically, in the microwave circuit described in patent documentation 1, the magnetic flux that inductor produces is easily through grounding electrode, and therefore the inductance value of inductor easily reduces.Then, if the thickness of substrate exists deviation, then the slippage of the inductance value of inductor can produce deviation.Consequently, in microwave circuit, the inductance value of inductor easily produces deviation.
On the other hand, in high frequency signal transmission line 10, the decline of the inductance value of inductor L can be suppressed.If the inductance value slippage of inductor L reduces, then the deviation of the inductance value slippage of inductor L reduces.Consequently, in high frequency signal transmission line 10, the deviation of the inductance value of inductor L can be reduced.
In addition, according to high frequency signal transmission line 10, the loss in inductor L can be reduced.More specifically, in the microwave circuit described in patent documentation 1, inductor in the shape of a spiral.When high-frequency signal flows through such inductor, because of skin effect, current convergence flows through the face (that is, close to the face of coil axes) of the inner circumferential side of the linear conductor forming inductor.In the microwave circuit described in patent documentation 1, the cross sectional shape of linear conductor is laterally long rectangle, and therefore current convergence flows through near the minor face of the inner circumferential side in laterally long rectangle.
On the other hand, in efficient signal transmission line 10, coil axes Ax extends to x-axis direction.Therefore, when high-frequency signal flows through inductor L, current convergence flows through near the long limit of the negative direction side in the z-axis direction in linear conductor 40a ~ 40h cross section.Equally, current convergence flows through near the long limit of the positive direction side in the z-axis direction in linear conductor 42a ~ 42g cross section.Thus, the region that the region that in high frequency signal transmission line 10, current convergence flows through is flow through than current convergence in microwave circuit is wide.Consequently, according to high frequency signal transmission line 10, compare the microwave circuit described in patent documentation 1, the loss in inductor L can be reduced.
In addition, according to high frequency signal transmission line 10, easily high frequency signal transmission line 10 can be bent.More specifically, when overlooking from z-axis direction, the linear conductor 40a ~ 40h of high frequency signal transmission line 10,42a ~ 42g are zigzag.Therefore, when overlooking from z-axis direction, in the interval being provided with inductor L, the harder part and be not provided with linear conductor 40a ~ 40h, 42a ~ 42g and softer part is alternately arranged in the direction of the x axis because being provided with linear conductor 40a ~ 40h, 42a ~ 42g in the x direction.That is, soft part is formed in the interval being provided with inductor L.Therefore, if high frequency signal transmission line 10 is at xz plane inner bending, then the part owing to not arranging linear conductor 40a ~ 40h, 42a ~ 42g and softness deforms.Therefore, easily high frequency signal transmission line 10 can be bent.
(variation 1)
Below, with reference to accompanying drawing, the high frequency signal transmission line 10a involved by variation 1 is described.Fig. 9 is the exploded view of the dielectric body 12 of high frequency signal transmission line 10a involved by variation 1.For the stereoscopic figure of high frequency signal transmission line 10a, quote Fig. 1.
High frequency signal transmission line 10a is mainly different from high frequency signal transmission line 10 on the direction that coil axes Ax extends.More specifically, as shown in Figure 9, in high frequency signal transmission line 10a, coil axes Ax extends to y-axis direction.Thus, the direction (x-axis direction) of coil axes Ax extension with the coupling part from signal line 20a, 20b and inductor L is orthogonal.
In high frequency signal transmission line 10a as above, same with high frequency signal transmission line 10, also while the decline of inductance value suppressing inductor L, the slimming of high frequency signal transmission line 10a can be realized.
In addition, in high frequency signal transmission line 10a, linear conductor 40a ~ 40f, 42a ~ 42e extend to the direction tilted slightly relative to x-axis direction.Signal line 20a, 20b extend to x-axis direction.Thus, signal line 20a, 20b and linear conductor 40a ~ 40f, 42a ~ 42e extend to roughly the same direction, and the sense of current flowing through them is also roughly equidirectional.Therefore, the direction of the electromagnetic field produced in signal line 20a, 20b and linear conductor 40a ~ 40f, 42a ~ 42e is also roughly the same.Consequently, the electromagnetic field that the interference of electromagnetic field signal line 20a, the 20b that linear conductor 40a ~ 40f, 42a ~ 42e can be suppressed to produce produce.Therefore, by arranging inductor L, inhibit the variation of the transmission characteristic of signal line 20a, 20b.
(variation 2)
Below, with reference to accompanying drawing, the high frequency signal transmission line 10b involved by variation 2 is described.Figure 10 is the exploded view of the dielectric body 12 of high frequency signal transmission line 10b involved by variation 2.About the stereoscopic figure of high frequency signal transmission line 10b, continue to use Fig. 1.
High frequency signal transmission line 10b is mainly different from high frequency signal transmission line 10 on the direction that coil axes Ax (not shown) extends.More specifically, as shown in Figure 10, in high frequency signal transmission line 10b, coil axes Ax and x-axis direction and y-axis direction all not parallel.Thus, coil axes Ax relative to the direction (x-axis direction) of signal line 20a, 20b extension from inductor L in being greater than the angle that 0 ° is less than 90 °.
In high frequency signal transmission line 10b as above, same with high frequency signal transmission line 10, also while the decline of inductance value suppressing inductor L, the slimming of high frequency signal transmission line 10b can be realized.
(variation 3)
Below, with reference to accompanying drawing, the high frequency signal transmission line 10c involved by variation 3 is described.Figure 11 is the exploded view of the dielectric body 12 of high frequency signal transmission line 10c involved by variation 3.About the stereoscopic figure of high frequency signal transmission line 10c, continue to use Fig. 1.
The difference of high frequency signal transmission line 10c and high frequency signal transmission line 10 is also to comprise earthing conductor 24.Next, centered by above-mentioned difference, high frequency signal transmission line 10c is described.In addition, for the structure identical with high frequency signal transmission line 10 in high frequency signal transmission line 10c, mark identical reference label.
The dielectric body 12 of high frequency signal transmission line 10c is by stacked and form from the positive direction side direction negative direction side in z-axis direction according to this order by protective layer 14 and dielectric sheet material 18a ~ 18d.
Linear conductor 42a ~ the 42g of high frequency signal transmission line 10c is formed on the surface of dielectric sheet material 18b.The structure of the linear conductor 42a ~ 42g of high frequency signal transmission line 10c is identical with the structure of the linear conductor 42a ~ 42g of high frequency signal transmission line 10, therefore omits the description.
In high frequency signal transmission line 10c, signal line 20a, 20b and linear conductor 40a ~ 40h are formed on the surface of dielectric sheet material 18c.In addition, signal line 20a, 20b of high frequency signal transmission line 10c and the structure of linear conductor 40a ~ 40h identical with signal line 20a, 20b of high frequency signal transmission line 10 and the structure of linear conductor 40a ~ 40h, therefore omit the description.
In addition, high frequency signal transmission line 10c also comprises via hole conductor b3, b4.Via hole conductor b3 runs through near the central authorities of connecting portion 18b-b in the z-axis direction.Via hole conductor b1, b3 are connected with each other thus form a via hole conductor, are connected by outside terminal 16a with the negative direction side end in the x-axis direction of holding wire 20a.
Via hole conductor b4 runs through near the central authorities of connecting portion 18b-c in the z-axis direction.Via hole conductor b2, b4 are connected with each other thus form a via hole conductor, are connected by outside terminal 16a with the positive direction side end in the x-axis direction of holding wire 20b.
As shown in figure 11, earthing conductor 24 (the second earthing conductor) is arranged in the negative direction side more leaning on z-axis direction in dielectric body 12 compared with signal line 20a, 20b, more specifically, earthing conductor 24 is arranged on the surface of dielectric sheet material 18d.Earthing conductor 24 extends along signal line 20a, 20b in the direction of the x axis on the surface of dielectric sheet material 18d, and as shown in figure 11, earthing conductor 24 is relative with signal line 20a, 20b across dielectric sheet material 18c.Earthing conductor 24 is made by the metal material that the resistivity being main component with silver, copper is less.
The surface that earthing conductor 24 is formed at dielectric sheet material 18d refers to and forms metal forming on the surface of dielectric sheet material 18d by plating, and pattern is carried out to metal forming form earthing conductor 24, or in the surface mount metal forming of dielectric sheet material 18d, and pattern is carried out to metal forming form earthing conductor 24.In addition, owing to implementing smoothing techniques to the surface of earthing conductor 24, therefore, the surface roughness in the face connected with dielectric sheet material 18d of earthing conductor 24 is greater than the surface roughness in the face do not connected with dielectric sheet material 18d of earthing conductor 24.
In addition, earthing conductor 24 is made up of primary conductor 24a, terminal conductor 24b, 24c.Primary conductor 24a is arranged on the surface of line part 18d-a, and extends in the direction of the x axis.And primary conductor 24a is by alternately arranging the multiple openings 30 not being formed with conductor layer and the part being formed with conductor layer and multiple bridge part 60 along signal line 20a, 20b, thus stepped.As shown in figure 11, when overlooking from z-axis direction, opening 30 is the rectangle of long side direction in x-axis direction, overlapping with signal line 20a, 20b.Thus, when overlooking from z-axis direction, signal line 20a, 20b and opening 30 and bridge part 60 alternately overlapping.In addition, opening 30 equally spaced arranges.
Terminal conductor 24b is arranged on the surface of connecting portion 18d-b, and is the straight-flanked ring of the central authorities surrounding connecting portion 18d-b.Terminal conductor 24b is connected with the negative direction side end in the x-axis direction of primary conductor 24a.
Terminal conductor 24c is arranged on the surface of connecting portion 18d-c, and is the straight-flanked ring of the central authorities surrounding connecting portion 18d-c.Terminal conductor 24c is connected with the positive direction side end in the x-axis direction of primary conductor 24a.
As mentioned above, earthing conductor 22 is not provided with opening, and is provided with opening 30 at earthing conductor 24.Thus the area that earthing conductor 24 is relative with signal line 20a, 20b is less than earthing conductor 22 area relative with signal line 20a, 20b.
In addition, signal line 20a, 20b and earthing conductor 22 distance is in the z-axis direction larger than signal line 20a, 20b and earthing conductor 24 distance in the z-axis direction.
Here, the characteristic impedance of high frequency signal transmission line 10c mainly based on the relative area between signal line 20 and earthing conductor 22 and distance and dielectric sheet material 18a, 18b relative dielectric constant and determine.Therefore, when the characteristic impedance of high frequency signal transmission line 10c is set as 50 Ω, such as, by signal line 20 and earthing conductor 22, the characteristic impedance of high frequency signal transmission line 10c is set as 55 Ω slightly higher than 50 Ω.Then, the shape of earthing conductor 24 is adjusted, make the characteristic impedance of high frequency signal transmission line 10c become 50 Ω because of signal line 20, earthing conductor 22 and earthing conductor 24.As mentioned above, earthing conductor 22 plays the effect of reference ground conductor.
Earthing conductor 24 is the auxiliary earth conductors also playing shielding action.In addition, as mentioned above, designing earthing conductor 24 is finally adjust to make the characteristic impedance of high frequency signal transmission line 10c become 50 Ω to carry out.Specifically, the size of opening 30, the live width etc. of bridge part 60 are designed.
As shown in figure 11, in high frequency signal transmission line 10c, the region being provided with opening 30 is called region A1, the region being provided with bridge part 60 is called region A2.That is, in the A1 of region, signal line 20a, 20b are overlapping with opening 30, and in the A2 of region, signal line 20a, 20b are overlapping with bridge part 60, not overlapping with opening 30.Region A1 and region A2 is alternately arranged in the direction of the x axis.The characteristic impedance of the high frequency signal transmission line 10c of region A1 is higher than the characteristic impedance of the high frequency signal transmission line 10c of region A2.
Multiple via hole conductor B1 ~ B3 run through line part 18a-a, 18b-a, 18c-a of dielectric sheet material 18a, 18b, 18c respectively along the z-axis direction, and line part 18a-a, 18b-a, 18c-a equally spaced form a line.When overlooking from z-axis direction, via hole conductor B1 ~ B3 is arranged on the positive direction side in the y-axis direction of signal line 20.And via hole conductor B1 ~ B3 is connected to each other, thus form a via hole conductor, thus connect earthing conductor 22 and earthing conductor 24.Via hole conductor B1 ~ B3 by with silver, copper for main component and the less metal material of resistivity make.
Multiple via hole conductor B4 ~ B6 run through line part 18a-a, 18b-a, 18c-a of dielectric sheet material 18a, 18b, 18c respectively along the z-axis direction, and line part 18a-a, 18b-a, 18c-a equally spaced form a line.When overlooking from z-axis direction, via hole conductor B4 ~ B6 is arranged on compared with signal line 20 more by the negative direction side in y-axis direction.And via hole conductor B4 ~ B6 is connected to each other, thus form a via hole conductor, thus connect earthing conductor 22 and earthing conductor 24.Via hole conductor B4 ~ B6 by with silver, copper for main component and the less metal material of resistivity make.
As mentioned above, signal line 20a, 20b and earthing conductor 22,24 are in three template strip lines configurations.
In high frequency signal transmission line 10c as above, same with high frequency signal transmission line 10, also while the decline of inductance value suppressing inductor L, the slimming of high frequency signal transmission line 10c can be realized.
(other execution mode)
High frequency signal transmission line involved by the utility model is not limited to high frequency signal transmission line 10,10a ~ 10c, can want to change in point range at it.
In addition, in high frequency signal transmission line 10, can between dielectric sheet material 18a and dielectric sheet material 18b further layered dielectric sheet material, form linear conductor 40a ~ 40h on the surface of this dielectric sheet material.Thus, signal line 20a, 20b and linear conductor 40a ~ 40h Distance geometry signal line 20a, 20b in the z-axis direction and linear conductor 42a ~ 42g close proximity in the z-axis direction.Therefore, signal line 20a, 20b is close to the coil axes Ax of inductor L.Owing to being difficult to produce magnetic flux near coil axes Ax, therefore inhibit the transmission characteristic change causing signal line 20a, 20b because of the impact of magnetic flux.
In addition, dielectric body 12 also can be the substrate without flexual hard.
In addition, high frequency signal transmission line 10,10a ~ 10c also can be used as the high frequency signal transmission line of the RF circuit substrates such as antenna front ends module.
In addition, high frequency signal transmission line 10,10a ~ 10c can not via connector 100a, 100b, and utilize solder to be connected to other circuit substrates via outside terminal 16a, 16b and terminal conductor 22b, 22c.
In addition, at least one of connector 100a, 100b can be installed on the back side of dielectric body 12.
In addition, also the structure of high frequency signal transmission line 10,10a ~ 10c can be combined.
In addition, in high frequency signal transmission line 10,10a ~ 10c, also can not some in signalization circuit 20a, 20b.

As mentioned above, the utility model for high frequency signal transmission line and electronic equipment useful, excellent in the performance of following this point: while suppressing the inductance value of inductor to decline, slimming to be realized.
