But, the antenna of prior art literature 1 and the mobile terminal possessing this antenna are by antenna 200 Merely it is arranged on bonnet 103, but this exists the problem that wireless communications efficiency is greatly reduced.

No. 1318707 (antenna of Republic of Korea's registered patent can be introduced as prior art literature 2 Device and mobile communication terminal).

Fig. 2 a represents that the moving body of the antenna assembly of the embodiment 1 being provided with prior art literature 2 leads to Letter terminal, wherein, (A) is the inside figure of housing, and (B) is Section A-A figure.

As shown in (A) and (B) of Fig. 2 a, the antenna of the embodiment 1 of prior art literature 2 Device 1A, by including the coil that is arranged at the side, the inside of the housing 5 of mobile terminal (such as mobile phone) The power supply part 10 of pattern 15, the magnetic portion being made up of the ferrite sheet being attached to power supply part 10 Part 19 and emission element 20 are constituted.

Emission element 20 plays the effect of antenna, launches the transmission signal supplied by power supply part 10 And obtain reception signal and be supplied to power supply part 10, described emission element 20 is at housing 5 Side, the inside constituted with the film of metal or the form of paper tinsel.

The lamination that power supply part 10 is laminated by multiple dielectric layers (thermoplastic resin film) Body is constituted, and coil pattern 15 is will to be respectively arranged at multiple ring-shaped conductors of multiple dielectric layer, logical Cross the interlayer conductors (not shown in (B) of Fig. 2 a) such as via conductor, with to the stacking of laminated body Direction possesses the mode of wireline reel, connects into coil with spiral (helical) shape.

It addition, the two end portions of coil pattern 15 and IC tag etc. wireless being built in housing 5 Circuit connects.

Emission element 20 possesses peristome 21 at one part, and possesses and the limit of peristome 21 The slit portion 22 of edge connection.

One end of slit portion 22 is connected with peristome 21, and the other end is at the lateral edges of emission element 20 Place is open.That is, slit portion 22 open communication portion 21 and the lateral edges of emission element 20.

When the wireline reel direction viewing plane of coil pattern 15, the Zone Full of peristome 21 with The interior survey region of coil pattern 15 is overlapping, and coil pattern 15 is overlapping with emission element 20.

Fig. 2 b is the schematic diagram of the antenna assembly of the embodiment 1 of exploded representation prior art literature 2.

The assembling sequence of antenna assembly 1A as shown in Figure 2 b, is first being built-in with coil pattern 15 Power supply part 10 on adhere to magnetic part 19, and power supply part 10 is attached to emission element 20 On.

In antenna assembly 1A as constituted above, by comprising the power supply part of coil pattern 15 10, the transmission signal from the radio-circuit electrically connected with the two ends of coil pattern 15 is supplied to sending out Penetrate parts 20, and (receive electricity by the reception signal of power supply part 10 spontaneous emission parts 20 in the future Power) supply to radio-circuit.

Below, its operation is described in detail.

As it has been described above, the wireline reel direction of the coil pattern 15 possessed from power supply part 10 is observed flat During face, the peristome 21 of emission element 20 and the inside region of coil pattern 15 are overlapping.

Fig. 2 c be represent prior art literature 2 embodiment 1 antenna assembly coil pattern and The schematic diagram of the combination of emission element.

As shown in Figure 2 c, such as when sending wireless signal, signal code is from radio-circuit flow line Circular pattern 15, this electric current the induced field H produced is as shown in phantom in FIG. by peristome 21 It is scattered in perfect condition.Magnetic field H is scattered in perfect condition and refers to the center B of two magnetic field H and open The center of oral area 21 is consistent, and the gain of emission element 20 reaches maximum in this case.

Fig. 2 d is to represent in the antenna assembly of the embodiment 1 of prior art literature 2 at emission element Peristome periphery produce faradic schematic diagram.

As shown in Figure 2 d, by above-mentioned induced field H, the peripheral part at peristome 21 produces Faradic current I1, I2 (but the flow direction of electric current I1, I2 differs 180 °).

Specifically, as shown in Figure 2 e, faradic current I1, I2 flow through peristome 21 and slit portion 22 around, flows to the plane of emission element 20 and flows to emission element according to edge effect The surrounding edge edge of 20.

Fig. 2 e is to represent to flow through emission part in the antenna assembly of the embodiment 1 of prior art literature 2 The faradic schematic diagram of part surrounding edge edge, Fig. 2 f is the enforcement representing prior art literature 2 The antenna assembly of example 1 and the schematic diagram of the magnetic bonding state of read write line side antenna, wherein, (A) Representing embodiment 1, (B) represents comparative example.

Although it addition, in Fig. 2 e not shown electric current I2, but with electric current I1 reverse flow.

Owing to emission element 20 and coil pattern 15 are the most overlapped, therefore faradic current I1, I2 flow in coil pattern 15 to block the induced field produced because of coil pattern 15 The direction flowing that dynamic electric current is contrary.

Here, produce magnetic field according to faradic current I1, I2 at emission element 20, in whole transmitting Parts 20 flow through faradic current I1, I2.Especially, when the wireless communication that antenna assembly 1A processes When number being HF frequency band, as shown in (A) of Fig. 2 f, emission element 20 does not has flux to pass, because of This flux (Φ) at the peristome 21 using emission element 20 as inner side, with emission element 20 External margin is as forming relatively large loop on the path in outside.

Thus, the communication distance of antenna 40 with read write line can be expanded.

(A) of magnetic bonding state such as Fig. 2 f of the antenna 40 of this antenna assembly 1A and read write line Shown in.As comparative example, (B) of Fig. 2 f represents the situation omitting emission element 20.

In this comparative example, owing to there is not emission element 20, so flux (Φ) can not expand, Thus reduce the binding capacity with antenna 40.Therefore, occur both closer to communication instability on the contrary Phenomenon.

Here, following presentation is measured for the various sizes (size in length and breadth) of power supply part 10 and reads Write device antenna 40 can the measurement result of communication distance.It addition, be to eliminate transmitting in bracket In the comparative example of parts 20 can communication distance.

As 22.5mm × 19mm, 0～43mm (0～23mm)

As 22.5mm × 18mm, 0～41mm (0～19mm)

As 22.5mm × 17mm, 0～39mm (-)

As 22.5mm × 16mm, 0～38mm (-)

Fig. 2 g is that wireless signal is UHF in the antenna assembly of the embodiment 1 of prior art literature 2 Operation schematic diagram during frequency band.

So, in emission element 20, by faradic current I1, I2 generation magnetic field H, and the same day When the wireless signal that line apparatus 1A processes is high frequency band especially UHF frequency band, as shown in Figure 2 g, Produce electric field E by this magnetic field H, produce magnetic field H by this electric field E, thus by such Chain, on whole emission element 20, the distribution of electromagnetic field expands in two dimensions.And, pass through The distribution of this electromagnetic field sends wireless signal because have in whole emission element 20 faradic current I1, I2 flows through, so communication distance can be expanded.

It addition, peristome 21 connects slit portion 22, so the flowing of this faradic current I1, I2 It is restricted at slit portion 22, thus produces potential difference (formation capacity).Therefore, can be by narrow Length L1 in seam portion 22 or the amount of width L2 Perceived control induced current I1, I2 or distribution, thus control Make whole emission element 20 produce electric field and the amount in magnetic field.As a result, can control to send signal Gain.

As it has been described above, can control to send to launching by length L1 of slit portion 22 or width L2 The gain of the wireless signal of parts 20.Specifically, length L1 of slit portion 22 is the biggest or width L2 is the least, then gain becomes big.

As shown in (B) of Fig. 2 a, the ring-shaped conductor that each dielectric layer of power supply part 10 has is excellent Choosing is spaced one from certain intervals by parallel multiple line conductors and is formed.That is, at prior art literature 2 Embodiment 1 in, be made up of two parallel line conductors with the conductor of ring-type formation, thus existed Also having flux to pass between two line conductors, the magnetic field being therefore excited is in coil pattern 15 The direction expansion that heart direction is i.e. vertical with wireline reel, thus can effectively utilize flux.It addition, can lead to Cross the quantity in parallel increasing ring-shaped conductor, reduce the D.C. resistance of ring-shaped conductor.As a result, can improve The gain of wireless signal.

In equivalent circuit as shown in Figure 2 c, illustrate only coil pattern 15 as power supply circuits, In addition to the inductance of coil pattern 15 self is used as inductance composition, due to coil pattern 15 such as It is made up of the ring electrode of stacking described in upper, the parasitism that therefore will be formed between the ring electrode of each layer Electric capacity is used as capacitive component.As long as it addition, power supply part 10 comprising at least one coil pattern 15 , and when power supply circuits have certain resonant frequency, such as, could be included for regulation The capacitive component of resonant frequency or inductance composition.

In the embodiment 1 of prior art literature 2, power supply circuits (coil pattern 15) have one Fixed resonant frequency, the frequency of the wireless signal preferably sending with emission element 20/receiving is actually Identical with this resonant frequency.Here, " practically identical " refers to the resonance frequency that power supply circuits are had The frequency band of rate and the frequency band of wireless signal sending/receiving with emission element 20 are basically identical.

So, due to send signal and/or receive the frequency of signal actually with the resonance of power supply circuits Frequency is identical, therefore can obtain have be hardly dependent on the shape of emission element 20 or material, The shape of the housing 5 of support emission element 20 or the antenna assembly of the frequency characteristic of material.

In other words, according to the peristome 21 in emission element 20 or the shape of slit portion 22 or material, Or the shape of the coil pattern 15 in power supply part 10 or material, determine the frequency band of wireless signal, And realize the coupling of the impedance of emission element 20 and radio-circuit (signal processing part).

It is therefore not necessary to the change peristome 21 of emission element 20 or the shape of slit portion 22 or coil The shape of pattern 15 can realize the antenna assembly corresponding with various mobile communication terminals.

It addition, the magnetic part 19 overlapped with power supply part 10 effectively with emission element 20 In conjunction with to prevent in coil pattern 15, the magnetic field of generation is to external leakage, it addition, also have by resistance Break the magnetic field produced in outside to the function preventing communication performance from deteriorating.

It addition, in the embodiment 1 of prior art literature 2, power supply part 10 and emission element 20 electromagnetic fields combine, therefore without must take into the resistance between power supply part 10 and emission element 20 Anti-coupling.

That is, according to the embodiment 1 of prior art literature 2, as it has been described above, narrow by design effectively The shape in seam portion 22 is easily controlled the gain of wireless signal.

The peristome 21 of emission element 20 and the interior survey region almost all of coil pattern 15 are overlapping, The area of peristome 21 is almost identical with the area in the interior survey region of coil pattern 15 is advisable.

This is because the magnetic field H (refer to Fig. 2 c) that coil pattern 15 produces is because of emission element 20 And effectively propagate, suppress loss, thus improve gain.

It addition, make the interior survey region almost all overlap of peristome 21 and coil pattern 15, thus Whole coil pattern 15 is made to be overlapped in emission element 20.It addition, emission element 20 thus can be passed through Produce big faradic current, thus expand communication distance further.But, if peristome 21 He The inside region of coil pattern 15 overlap, emission element 20 and coil pattern 15 at least partially A part is overlapping.

Additionally, it is preferred that the area of emission element 20 is more than the face of the part formed by coil pattern 15 Long-pending.

Because the area of emission element 20 is more than the area of the part formed by coil pattern 15, sense Electric current forms big loop flow, such that it is able to expand communication distance further.

For the shape of slit portion 22, as shown in the present embodiment 1, during linearly type, be conducive to processing, But formed also may be used with the shape of tortuous (meandering) or the shape of bending.It addition, power supply part 10 can also form coil pattern 15 on single layer substrate.

But, the antenna assembly of prior art literature 2 and mobile communication terminal are due to coil pattern 15 is the most overlapping with emission element 20, so wireless communications efficiency can not be made to reach to maximize.
