Description

Antenna

Technical field

The present invention relates to a kind of built-in aerial, more particularly, relate to a kind of built-in aerial that can enhance productivity, because it is not by making the built-in aerial that the built-in aerial metal part divides assembling to form respectively, but bar line wherein is bent to the shape of wanting and is anchored on the built-in aerial of synthetic resin material surface.

Background technology

Flush type antenna as shown in Figure 1 relates to and becomes elongated to reduce the device of wireless device overall volume, to be different to be installed in the outer exterior antenna of wireless device.

That is to say that described built-in aerial becomes the folded monopole antenna that sends and receive radio signals by the folded monopole antenna that increase is installed on the wireless device.

Be known that, such built-in aerial has thoroughly improved by obtaining a kind of built-in aerial pattern impedance has been reduced to the quality that metallic resistance rate level sends and receives radio signals, and described built-in aerial pattern is made up of with the offset point structure that forms C value capacitor the distributing point structure and parallel being positioned at described distributing point structure adjacent position of upwards advancing to form L value inductor.

Yet, conventional built-in antenna is is seldom researched and developed the wireless device that is used to be installed in elongated shapeization, for example on the mobile phone, especially almost do not have research and development to be used for the built-in aerial of CDMA frequency type or PCS frequency type, this has been regarded as the obstacle to the miniaturization mobile phone development.

Recently, as shown in Figure 2, those are developed according to the elongated built-in aerial of becoming of aforementioned miniaturization mobile phone.Fig. 2 is the perspective view that conventional built-in antenna is shown.So that metal part 20 is fixed on the surface of synthetic resin susceptor material 10, so it has the shortcoming that needs multiple operation, low production efficiency and high cost to described conventional built-in antenna by artificial assembling.

Another shortcoming of described conventional built-in antenna is assembly working difficulty and error incidence height, and this is not only because impedance transformer and amplifier for constructing separately, are gone back because they are arranged on the main body.

Summary of the invention

Technical problem

Therefore, the present invention is in order to solve aforementioned general issues, its main purpose provides a kind of built-in aerial, in described built-in aerial, the pedestal of built-in aerial is made by the synthetic resin material, and a plurality of boss that repeat continuously with certain interval are formed on the surface of every part, and the bent stick line is fixed between these boss with welding, so that they can easily be made, simultaneously to shortening production technology and reducing production cost and make very big contribution.

Embodiment

Now, describe the preferred embodiments of the present invention with reference to the accompanying drawings in detail.

Fig. 3 is the perspective view that built-in aerial of the present invention is shown; And Fig. 4 is the profile that built-in antenna arrangement of the present invention is shown.

As shown in these figures, described built-in aerial of the present invention comprises pedestal 30, bar line 40 and terminals 50.Especially, as shown in Figure 3,, on each surface of described pedestal 30, repeat to be formed with a plurality of boss continuously with certain interval G by the spray up moulding of synthetic resin material.

At this moment, described clearance G between the boss is decided by the thickness of described bar line 40, by using these boss, can be with described bar line 40 bendings, so that on front surface 32, left and right sides surface 33 and the upper surface 34 and the lower surface 35 of described pedestal 30, arrange on a large scale.

In addition, when during with the definite shape curved arrangement, inserting the described bar line of the certain thickness D in the described clearance G between described boss and should firmly be fixed, thereby do not allow it to move along the described gap of 31 of described boss.

Then, the described bar line 40 that is connected between the described boss 31 is connected in tangent terminals 50, and described terminals are arranged on the side of described pedestal 30 to form described built-in aerial.

Described bar line 40 is preferably copper cash, but can use any other Metallic rod line that is suitable for antenna.

By using the method for example have the crooked and insertion rod line of the manipulator that is fixed on the described pedestal 30 on the assembly fixture, this kind job step easily realizes automation.In addition, according to the present invention, after in the described clearance G between the described bar line 40 insertion boss 31, it is preferred breaking away from by the anti-stopping bar line in the end of some boss of hot melt.

That is to say, as shown in Figure 4, by hot melt distortion prevent that described bar line 40 breaks away from so that the front end area of boss 31 bigger be preferred.At this moment, it is preferred providing the manipulator with thermofusion device to carry out hot melt work behind bending and the insertion rod line immediately.

Fig. 5 to 7 illustrates the built-in aerial according to another embodiment of the present invention.

In the described built-in aerial shown in Figure 5, pedestal 30a has a pair of board 36, and described board is crooked at a predetermined angle and keep the shape of V in the portion of being in contact with one another, thereby stops the radio wave reflection and they are absorbed easily.After this, identical with previous embodiment boss 31 is formed on the described a pair of board 36 to form described built-in aerial.

Here, described board 36 has the portion of turning down 37 in the bottom, and bump bonding 39 is formed on the base plane of each described portion that turns down, so that be installed in like a cork on the printed circuit board (not shown).

In Fig. 6, in the built-in aerial according to Fig. 5 embodiment, the described portion 37 that turns down only is formed in arbitrary board 36.If also nonessential use two is in conjunction with projection 39 when being installed to described printed circuit board, this can be used.

In Fig. 7, plate shape connecting portion 38 is formed between a pair of board 36.When bar line 40 being arranged as when the opposite side of the described board 36 of a side direction of described board 36 extends, this connecting portion 38 plays the effect that alleviates with the bent stick line.

Certainly, preferably, boss 31 also is formed in this connecting portion 38 with the introducing that helps bar line 40 and fixing.

Industrial applicibility
