It is connected to the access area of second layer 100B.In addition, second transmission line 162 crisscrosses signal wire 122, signal wire 124 and access area
130.For example, signal wire 122, signal wire 124 and access area 130 are perpendicular to second transmission line 162, so that on circuit board
Wiring it is more efficient, improve the area utilization rate of circuit board.It is worth noting that, between signal wire 122 and access area 130
Every a spacing X1, a spacing X2 is spaced between signal wire 124 and access area 130.For example, spacing X1 is equal to spacing X2
(that is, first spacing).In addition, signal wire 122 and 124 is respectively provided with line width W122 and W124.The impedance of first transmission line 120
Value is associated with the line width W122 and W124 of the first spacing and signal wire 122 and 124.For example, as line width W122 and W124
Numerical value when being fixed, the impedance value of the more big then first transmission line 120 of the first spacing is bigger.When the numerical value of the first spacing is to fix
When, the impedance value of the more big then first transmission line 120 of the numerical value of line width W122 and W124 is smaller.
Specifically, the first transmission line 120 including signal wire 122, signal wire 124 and access area 130 is one coplanar
The electric field of the up and down direction of first transmission line 120 itself can be guided and be changed by waveguide (Coplanar Waveguide)

And the length L130 in this two-wire area is greater than or equal to the width W160 of slot 160.In another embodiment, the length in two-wire area
L130 also may be defined as the distance between two interlayer hole 130V of access area 130, and the present invention is not limited to this.
Since first transmission line 120 is including single line area 126 and 128 and by signal wire 122,124 and 130 institute of access area
The two-wire area of composition can allow adjustment spacing X1 and X2 and line to reach impedance matching to reduce the loss of signal transmission
Wide W122 and W124 is to obtain the impedance value of ideal signal wire 122 and 124.In one embodiment, the impedance value in single line area 126
It is equal to the equivalent impedance of the signal wire 122 and 124, and the equivalent impedance of signal wire 122 and 124 is equal to single line area

The numerical value of X4 is different, that is, the second spacing is not equal to third spacing.In addition, the impedance value of first transmission line 120 is associated with
The line width W122 and W124 of spacing X1, X2, X3 and X4 and signal wire 122 and 124.For example, as line width W122 and W124
Numerical value when being fixed, the impedance value of the equidistant more big then signal wire 122 and 124 of X1, X2, X3 and X4 is bigger.As X1, X2, X3
When with the equidistant numerical value of X4 being fixed, the impedance value of the more big then signal wire 122 and 124 of the numerical value of line width W122 and W124 more
It is small.User can allow that adjustment X1, X2, X3 and X4 be equidistant and line width W122 and W124, to obtain ideal signal wire
122 and 124 impedance value.
It is worth noting that, in one embodiment, the width W130 of access area 130 is greater than or equal to signal wire 122 and 124
Three times of line width W122 and W124.The width W132 in the region adjacent with signal wire 122 of access area 132 is greater than or equal to signal
The width W134 of three times of the line width W122 of line 122, the region adjacent with signal wire 124 of access area 134 is greater than or equal to signal
Three times of the line width W124 of line 124.In other words, the present invention is not intended to limit the not region adjacent with signal wire 122 of access area 132
Width, do not limit the width in the not region adjacent with signal wire 124 of access area 134 yet.Above-mentioned access area 132 and 134 not with
The adjacent region of signal wire 122 and 124, can according to circuit design needs and be configured to arbitrary shape or size.It is noted that
, for signal wire 122 or 124, the width of two access areas of the adjacent two sides in left and right is both greater than or equal to it
Three times of body line width.Therefore, when signal wire 122 or 124 transmits radio signal, more than the three times width of the left and right sides connecing
Area can lock the electric field of its left and right directions.In this way, the up and down direction of signal wire 122 or 124 can be further reduced
Electric field, and improve between first transmission line 120 and second transmission line 162 because of disturbing effect caused by grooving or cabling.It lifts
For example, when the radio frequency band of 20.6GHz uses transmission line structure 10 provided by the present invention, the minimum isolation of signal
It (isolation) is about -20.3dB, and using the minimum isolation of the signal of conventional backing plate cabling is about -10.2dB.Thus may be used
Know, since electric field is changed into the electric field of horizontal direction by transmission line structure 10, thus preferable isolation can be provided, effectively completely cut off
