Embodiment
Below, will describe the preferred embodiments of the present invention in detail with reference to accompanying drawing.
Fig. 1 is the figure that illustrates according to the schematic structure of the antenna assembly of the embodiment of the invention.Antenna assembly comprises the flexible print circuit (FPC) 20 as flexible portion.In this embodiment, two conductive patterns that on the flexible print circuit on the transparent panel 23 20, are formed for high frequency band (HB) and low-frequency band (LB) are as antenna element 21, and this antenna element 21 is carried out feed as primary radiator.In this example, adopt the multiband linear antenna corresponding as an example with a plurality of frequency bands.For multiband, for example, the 2.5GHz etc. that considers to be used for cellular 800MHz channel and 1950MHz and be used for Bluetooth (registered trade mark).
Two antenna elements 21 all have: gold-plated contact point 21a, and gold-plated contact point 21a is a feed of treating feed; Non-mesh portion 21b follows in gold-plated contact point 21a back; With mesh portion 21c, follow in non-mesh portion 21b back.
Preferably, near the zone the feed 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 in this embodiment is solid, and owing to the reason of describing after a while is 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 among Fig. 2.For example, flexible print circuit 20 can be sandwiched between two transparent components with the opposite face that faces with each other.In this case, this layer clear binder 25 can omit.
Fig. 3 illustrates the example of 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 resistive component thus.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).
At the line width of confirming conductor wire 41 during, need satisfy the requirement of light transmittance of radiation characteristic and the mesh portion of antenna with the line interval.
Fig. 4 is the curve chart that the result of study of the experiment of antennas operating under the 800MHz frequency band that the present invention is applied in mobile telephone terminal, often adopt is shown.In this curve chart, transverse axis display frequency (MHz), the longitudinal axis shows the antenna efficiency of measuring (dB).Experimentize to the antenna element of processing by the Copper Foil element that does not have mesh portion and (being made of copper) antenna element with mesh portion.For antenna element, use two kinds of situation of conductor wire with mesh portion.A kind of situation is the line conductor wire of (spacing) at interval of thickness and the 220 μ m of line width with 10 μ m, 10 μ m.Another kind of situation is the line conductor wire of (spacing) and the size identical with the former at interval with 400 μ m.
Curve chart from Fig. 4; Can confirm to compare with the Copper Foil element that does not have mesh portion; Antenna element with mesh portion has the resonance frequency of shifting to lower frequency side a little, but under the situation of the spacing with 220 μ m, has similar basically antenna performance.Can confirm under the situation of spacing, thereby the too big conductor losses in the interval of mesh increases, and makes antenna efficiency reduce about 1dB with 400 μ m.
When the line width of the conductor wire of confirming mesh portion, line width is big more, and the radiation characteristic of the antenna of acquisition is good more, and line is more little at interval, and the radiation characteristic of acquisition is good more.On the other hand, for the light more than the grade that obtains to hope (visible light), line width is more little, and the result of acquisition is good more.In addition, line is long more at interval, and the result of acquisition is good more.
By this way, between the radiation characteristic of antenna and light transmittance, there is trade-off relation.Therefore, in order to satisfy two requirements, must carry out following research.
For the lower limit of the line width (and thickness) of confirming conductor wire can not increase conductor losses to improve light transmittance, need to consider skin depth to the target frequency of antenna element.High-frequency current has the characteristic that is called kelvin effect, and promptly electric current is many flows in surface of conductors.Skin depth is the mainly index of the degree of depth of mobile " exodermis " of indication electric current.
Consider the direction of the upper surface and the lower surface of conductor wire, think that line width (and thickness) need be that the twice of skin depth is not so that increase conductor losses.For example, if conductor material is a copper, then the skin depth to low band frequencies 850MHz is about 3 μ m, and 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 the above-mentioned example is enough line widths.
By this way, hope the line width W (and thickness) of the conductor wire of mesh portion is set to the twice of conductor material to the skin depth of the target frequency of antenna element.
Aspect this, for high frequency band, skin depth has littler value, thinks that therefore the line width of confirming to low-frequency band has just enough used.
For the light transmittance more than the grade that obtains to hope (visible light), when the line width of the conductor wire of the mesh portion 21c that constitutes antenna element 21 diminishes and more favourable when the line interval is also elongated.If suppose from the light transmittance that the relation between line width W shown in Fig. 3 and the line interval D obtains to be minimum necessary, then the relation between line width W and the line interval D becomes D >=22W basically.
In this case, can consider the degree of percent opening (aperture rate) as light transmittance (visible light).Percent opening is the ratio of aperture portion branch with respect to the area of mesh portion.In the example of Fig. 3, obtain percent opening through following expression.
Percent opening=220 * 220/{ (220+10) * (220+10) }=0.915
That is to say that for the transmissivity that obtains to 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, shown in Fig. 5 A, antenna assembly comprises the combination with respect to the low-band antenna element 21 (LB) and the high-band antenna element 21 (HB) of earthing conductor 61.Distributing point and has been arranged unshowned antenna-matching circuit in the accompanying drawing here between each antenna element 21 and earthing conductor 61.
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 in addition current concentrations are near distributing point.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 in addition current concentrations are near distributing point.
By this way, under the situation of 1/4 wavelength (λ/4) antenna that in mobile telephone terminal, often adopts, a large amount of electric currents flow near distributing point.Therefore, as stated, be solid or thinner if make the mesh of this part, then can reduce by current concentration on thin antenna element and the reduction of the antenna efficiency that the conductor losses that causes causes.
Fig. 6 A and 6B illustrate the modification of mesh portion 21c.In this example, in mesh portion 21c, a large amount of electric currents flow through along the line width of the conductor wire 42 of outermost longitudinal direction, this mesh portion of antenna element line width greater than inner conductive line 41.Fig. 6 A illustrates the parallel network structure of inner conductive line 41 and outermost conductor wire 42.Fig. 6 B illustrates the network structure of inner conductive line 41 oblique arrangement.Cancellated line width W and line interval D are confirmed by thin conductor wire 41 among Fig. 6 B.
Fig. 7 A and 7B illustrate the cancellated other modification of mesh portion.Above-mentioned example has shown such structure: in this structure, inner conductive line 41 is the parallel lines that are perpendicular to one another at least.Yet, identical along the conductor wire 41 of the longitudinal direction of antenna element in the example of Fig. 7 A and 7B with above-mentioned example, 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 along the longitudinal direction of the antenna element separation according to rule.Yet 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.
Though 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 have such structure: in this structure, make that a large amount of electric current flows through along the line width of the conductor wire of outermost longitudinal direction, mesh portion of antenna element line width greater than the inner conductive line.
Fig. 8 illustrates another example of the antenna element 21 with multistage mesh density.To giving identical Reference numeral, and omit the description of repetition with the element components identical shown in Fig. 1.In this example, the mesh portion 21d with mesh density higher than mesh portion 21c is between mesh portion 21c and non-mesh portion 21b.That is to say that 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.As another selection, mesh density can change continuously.
