Embodiment
Below, describe with reference to the accompanying drawings the preferred embodiments of the present invention in detail.
Fig. 1 is the figure illustrating according to the schematic structure of the antenna assembly of the embodiment of the present invention.Antenna assembly comprises the flexible print circuit (FPC) 20 as flexible portion.In this embodiment, on flexible print circuit 20 on transparent panel 23, be formed for two conductive patterns of high frequency band (HB) and low-frequency band (LB) as antenna element 21, this antenna element 21 is carried out feed as primary radiator.In this example, adopt the multiband linear antenna corresponding with multiple frequency bands as an example.For multiband, for example, consider for cellular 800MHz channel and 1950MHz and for the 2.5GHz of Bluetooth (registered trade mark) etc.
Two antenna elements 21 all have: gold-plated contact point 21a, and gold-plated contact point 21a is the feed part for the treatment of feed; Non-mesh portion 21b, follows after gold-plated contact point 21a; With mesh portion 21c, follow after non-mesh portion 21b.
Preferably, near the region feed part of antenna element 21 has thinner mesh or solid (the inside is not empty).In this example, each antenna element 21 has the length of 1/4 wavelength (/ 4) of corresponding frequencies, and the distolateral only about half of mesh portion 21c that is used as of antenna element 21.Non-mesh portion 21b is in this embodiment solid, and because the reason of describing is after a while positioned at supply side.
Fig. 2 illustrates the schematic sectional view of the mesh portion 21c of flexible print circuit 20.
The structure of flexible print circuit 20 is not limited to the structure in Fig. 2.For example, flexible print circuit 20 can be sandwiched between two transparent components with the opposite face facing with each other.In this case, this layer of clear binder 25 can omit.
Fig. 3 illustrates the example of the structure of mesh portion 21c.In this example, mesh is foursquare, and conductor wire 41 has the line interval of line width and the 220 μ m of 10 μ m.Article two, intersecting lens is assumed to be electrical connection.Thus, current flow path has planar structure, can reduce thus resistive component.In order to obtain stable contact, preferably do not use fabric construction, but preferably use etched slab structure (metallic plate is copper coin in this embodiment).
In the time determining the line width of conductor wire 41 and line interval, need to meet the requirement of the radiation characteristic of antenna and the light transmittance of mesh portion.
Fig. 4 illustrates the curve chart that the present invention is applied to the result of study of the experiment of the antenna of working under the 800MHz frequency band often adopting in mobile telephone terminal.In this curve chart, transverse axis display frequency (MHz), the antenna efficiency (dB) of longitudinal axis display measurement.Test for the antenna element of being made by the Copper Foil element without mesh portion and (being made of copper) antenna element with mesh portion.For the antenna element with mesh portion, use two kinds of situations of conductor wire.A kind of situation is the conductor wire at line width, the thickness of 10 μ m and the line interval (spacing) of 220 μ m with 10 μ m.Another kind of situation is to have the line interval (spacing) of 400 μ m and the conductor wire of the size identical with the former.
Curve chart from Fig. 4, can confirm compared with not thering is the Copper Foil element of mesh portion, the antenna element with mesh portion has the resonance frequency of shifting to a little lower frequency side, but has substantially similar antenna performance in the case of having the spacing of 220 μ m.Can confirm the spacing in the case of thering are 400 μ m, thereby the too large conductor losses in the interval of mesh increases, and makes antenna efficiency reduce about 1dB.
In the time determining the line width of conductor wire of mesh portion, line width is larger, and the radiation characteristic of the antenna of acquisition is better, and line interval is less, and the radiation characteristic of acquisition is better.On the other hand, in order to obtain light (visible ray) more than the grade of hope, line width is less, and the result of acquisition is better.In addition, line interval is longer, and the result of acquisition is better.
By this way, between the radiation characteristic of antenna and light transmittance, there is trade-off relation.Therefore,, in order to meet two requirements, must carry out following research.
For the lower limit of line width (and thickness) of determining conductor wire is to improve light transmittance and can not increase conductor losses, need to consider the skin depth for the target frequency of antenna element.High-frequency current has the characteristic that is called kelvin effect, and flow in the many surfaces at conductor of electric current.Skin depth is the mainly index of the degree of depth of mobile " exodermis " of indicator current.
Consider the direction of upper surface and the lower surface of conductor wire, think that line width (and thickness) need to be that the twice of skin depth is not to increase conductor losses.For example, if conductor material is copper, be about 3 μ m for the skin depth of low band frequencies 850MHz, therefore minimum required line width becomes 5 to 7 μ m.From the viewpoint of the radiation characteristic of antenna, the line width of 10 μ m in above-mentioned example is enough line widths.
By this way, wish the line width W (and thickness) of the conductor wire of mesh portion to be set to the twice of conductor material for the skin depth of the target frequency of antenna element.
Aspect this, for high frequency band, skin depth has less value, therefore thinks and has just enough used for the definite line width of low-frequency band.
In order to obtain light transmittance (visible ray) more than the grade of hope, in the time forming the line width of conductor wire of mesh portion 21c of antenna element 21 and diminish and more favourable in the time that line interval is also elongated.If suppose that the light transmittance obtaining from the relation between the line width W shown in Fig. 3 and line interval D is minimum necessary, the relation between line width W and line interval D becomes D >=22W substantially.
In this case, can consider the degree of percent opening (aperture rate) as light transmittance (visible ray).Percent opening is that aperture portion is divided the ratio with respect to the area of mesh portion.In the example of Fig. 3, obtain percent opening by expression formula below.
Percent opening=220 × 220/{ (220+10) × (220+10) }=0.915
That is to say, in order to obtain the transmissivity of hope, percent opening is preferably more than 91%.
Fig. 5 illustrates the CURRENT DISTRIBUTION on the antenna element in the antenna assembly shown in Fig. 1.In this example, as shown in Figure 5 A, antenna assembly comprises the combination with respect to low-band antenna element 21 (LB) and the high-band antenna element 21 (HB) of earthing conductor 61.Distributing point, between each antenna element 21 and earthing conductor 61, and has been arranged unshowned antenna-matching circuit in the accompanying drawing here.
Be appreciated that for low-frequency band (in this example for 850MHz) from Fig. 5 B, a large amount of electric currents low-band antenna element 21 (LB) of flowing through, most of electric currents concentrate near distributing point in addition.In an identical manner, be appreciated that for high frequency band (in this example for 1950MHz) from Fig. 5 C, a large amount of electric currents high-band antenna element 21 (HB) of flowing through, most of electric currents concentrate near distributing point in addition.
By this way, 1/4 wavelength (λ/4) antenna often adopting in mobile telephone terminal, a large amount of electric currents are at distributing point Flow Structure Nearby.Therefore, as mentioned above, be solid or thinner if make the mesh of this part, can reduce to be concentrated on thin antenna element and the reduction of the antenna efficiency that the conductor losses causing causes by electric current.
Fig. 6 A and 6B illustrate the modification of mesh portion 21c.In this example, in mesh portion 21c, the line width of the conductor wire 42 of the outermost longitudinal direction along antenna element, this mesh portion that a large amount of electric currents are flowed through is greater than the line width of inner conductive line 41.Fig. 6 A illustrates the network structure that inner conductive line 41 is parallel with outermost conductor wire 42.Fig. 6 B illustrates the network structure of inner conductive line 41 oblique arrangement.In Fig. 6 B, cancellated line width W and line interval D are determined by thinner conductor wire 41.
Fig. 7 A and 7B illustrate the cancellated other modification of mesh portion.Above-mentioned example has shown such structure: in this structure, at least inner conductive line 41 is the parallel lines that are perpendicular to one another.But, in the example of Fig. 7 A and 7B, identical with above-mentioned example along the conductor wire 41 of the longitudinal direction of antenna element, but conductor wire 43 is perpendicular to conductor wire 41 and be the short line segment that connects adjacent conductive line 41.Conductor wire 43 is arranged according to regular interval along the longitudinal direction of antenna element.But their phase place moves between each conductor wire 41.In this example, phase shifts 180 degree, and the piece corresponding with mesh looks like and lays bricks.Aspect this, the amount of phase shift is not limited to 180 degree.
Although do not illustrate particularly in the figure, but in the network structure of Fig. 7 A and 7B, as shown in Figure 6A and 6B, can there is such structure: in this structure, make the line width of the conductor wire of the outermost longitudinal direction along antenna element, mesh portion that a large amount of electric currents flow through be greater than the line width of inner conductive line.
Fig. 8 illustrates another example of the antenna element 21 with multistage mesh density.Give identical Reference numeral to the element identical with the element shown in Fig. 1, and omit the description repeating.In this example, the mesh portion 21d that has the mesh density higher than mesh portion 21c is between mesh portion 21c and non-mesh portion 21b.That is to say, in this example, mesh density changes according to two-stage.The change of mesh density is not limited to two-stage, and mesh density can be according to more multistage change.Select as another, mesh density can change continuously.
