Describe the design process in detail.

The helical antenna having a two-dimensional (2D) planar spiral shape is designed to operate in two modes, a normal mode and an axial mode.

Normal mode produces the strongest radiation in the normal direction of the helical antenna axis. This happens when the diameter of the spiral is small compared to the wavelength.

Axial mode produces maximum radiation along the axis of the helical antenna. This occurs in axial mode when the circumference of the helix is about the wavelength.

In FIG. 4, the pitch angle of the helical antenna (

Figure 112010005412917-pat00001
) Can be expressed as in Equation 1.

Figure 112010005412917-pat00002

Where D represents the diameter of the spiral, C represents the circumference, S represents the pitch, the distance from the center of the spiral to the center, and L 0 represents the length of one wheel.

In addition, the radiation resistance R T applied to the helical antenna having the two-dimensional (2D) planar spiral shape by experiment can be expressed as in Equation (2).

Figure 112010005412917-pat00003

Subsequently, a half-power angle (θ), which is a measure of the sensitivity of directional directional helical antennas, is obtained by radiating resistance (R T ) applied to a helical antenna having a two-dimensional (2D) planar spiral shape. As can be seen, Equation 3 can be expressed.

Here, the half-value angle is an angle representing the sensitivity of the antenna directivity, and refers to an angle formed in two directions, which is one half of the maximum value of the main beam in the antenna's directivity. 1/1 of the maximum value of the main beam when the directivity characteristic is expressed by the electric field strength

Figure 112010005412917-pat00004
This is the angle between the two directions.

Figure 112010005412917-pat00005

That is, it has a unidirectional sensitive directivity characteristic in which one main lobe appears in the spiral axis direction and a side lobe appears in the spiral axis and the oblique direction. If the circumference of the helix is 1λ, the traveling wave current is distributed on the helix to obtain a single directivity.

At this time, considering the spiral winding as a unit antenna, if there are n windings, a helical antenna having a beam antenna composed of n elements is formed.

In the radiation type, the helical antenna having a circularly polarized antenna is formed because the spiral portions are symmetrical with respect to the spiral axis direction.

Subsequently, the efficiency of the helical antenna having the two-dimensional (2D) planar spiral shape according to the present invention is designed in consideration of the loss in the antenna structure and the input terminal.

The overall efficiency of the helical antenna can be expressed as Equation 4 below.

Figure 112010005412917-pat00006

Here, e 0 represents overall efficiency (dimensionless), e r represents reflection (mismatching) efficiency, e c represents conductor efficiency, and e d represents dielectric efficiency.

And,

Figure 112010005412917-pat00008
Z A is the antenna input impedance, and Z 0 is the characteristic impedance of the transmission line.

Since the helical antenna radiation efficiency is used in connection with gain and directivity, this can be expressed as in Equation 5.

Etching process

The hybrid antenna

Etching process is formed integrally with the mobile communication terminal case 110,

The etching and laminating step of coating copper on the mobile communication terminal case 110 and

Forming an antenna pattern by etching by using an etching solution formed by adding a corrosion inhibitor and an insoluble powder to an iron chloride solution to the laminating treatment site;

For the protection of the antenna pattern is made of a protective printing step of printing with a viscosity of 30,000 ~ 50,000 (cps) urethane.

In this case, the etching solution is used to prevent corrosion of the linear antenna pattern 20 and to form a high quality pattern, by using a corrosion inhibitor and an insoluble powder added to the iron chloride solution.

Iron chloride is a compound of iron and chlorine, and iron (III) iron (II) chloride, which is a chloride containing divalent and trivalent iron in addition to iron (II) chloride and iron (III) chloride, is known. Ferric chloride (II), also called ferrous chloride, exists as a Lorentzite with nickel chloride in natural iron or volcanic fumes, and has a melting point of 672 ° C, a boiling point of 1,023.4 ° C and a specific gravity of 2.99 (18 ° C).

Ferric chloride (III), also known as ferric chloride, is found in volcanic eruptions or meteorites and has a melting point of 300 ° C, a boiling point of 317 ° C and a specific gravity of 2.804 (11 ° C).

Looking at the etching mechanism using the iron chloride is shown in Scheme 1.

[Reaction Scheme 1]

FeCl 3 + Cu → FeCl 2 + CuCl

As in Scheme 1, iron ions oxidize copper to produce ferrous chloride and cupric chloride.

[Reaction Scheme 2]

FeCl 3 + CuCl → FeCl 2 + CuCl 2

As in Scheme 2, cuprous chloride produced in Scheme 1 further oxidizes copper to produce ferrous chloride and cupric chloride.

The etching solution uses a corrosion inhibitor and an insoluble powder to prevent the antenna pattern corrosion failure and to obtain a strong physical etching effect.

The corrosion inhibitor uses Benzotriazole.

The amount of the corrosion inhibitor is 0.40mM to 0.45mM / L with respect to the entire etching solution. If the corrosion inhibitor is less than 0.40mM / L, the probability of corrosion of the antenna pattern is high, and if the amount exceeds 0.45mM / L, the etching is almost performed. Since there is a problem that does not occur, the corrosion inhibitor is used in addition to the etching solution within the range of 0.40mM to 0.45mM / L.

And, the temperature used by the addition of the corrosion inhibitor is 40 ~ 50 ℃, when the temperature used by adding the corrosion inhibitor is less than 40 ℃ that the activity is lowered and the function of the corrosion inhibitor is added to the etching is not made There is a problem that does not have a problem, because if the etching rate is faster than 50 ℃ to proceed excessively, the temperature used by adding the corrosion inhibitor is maintained at 40 ~ 50 ℃.

The insoluble powder is 0.5 ~ 1㎛ TiO 2 , 0.25mM to 0.30mM / L is used for the entire etching solution. If the particle size of the insoluble powder is less than 0.5㎛ it is difficult to expect a physical etching effect, if it exceeds 1㎛ it may interfere with the spraying of the powder clustering, the particle size of the insoluble powder is 0.5 It is used in the range of ˜1 μm.

When the insoluble powder is less than 0.25mM with respect to the entire etching solution, it is difficult to expect a physical etching effect, and when the insoluble powder exceeds 0.30mM / L, the powder may interfere with the flow of the etching solution to prevent smooth etching. As such, the insoluble powder may be used in an amount of 0.25 mM to 0.30 mM / L based on the total etching solution.

Printing process

The printing process has the advantage of being able to realize an electronic device having a line width of several hundreds of micrometers, and having a high production speed and easy mass production. The printing process includes an inkjet process, a screen process, and a roll printing process, in which the quality of printing varies depending on the printing pressure and viscosity of the ink.

The hybrid antenna 300 is a conductive ink to form an antenna pattern by the inkjet printing method in the mobile communication terminal case 110, the conductive ink is water-based silver nano ink having a particle size of 10 ~ 25㎛ Dilute nano-silver ink in water to adjust the viscosity to 3.5 ~ 4.5cP.

When the viscosity is less than 3.5 cP, bleeding occurs, which causes a non-uniform ink transition, thereby causing an irregular line width. In addition, the line width is irregular, causing the bottleneck partially to increase the resistance. In addition, when the viscosity exceeds 4.5 cP, the ink transfer rate decreases and the print quality is lowered. Thus, the viscosity of the ink is maintained in the range of 3.5 to 4.5 cP.

Deposition Plating Process

A hybrid antenna pattern having a helical antenna 200 having a planar spiral shape is formed, and copper plating is performed on the pattern portion.

The deposition plating process (PVD) is for depositing a copper thin film, and the deposition material is vaporized and deposited in the absence of plasma. At this time, the temperature of the substrate is 200 ~ 1600 ℃, the deposition thickness is 100nm ~ 100㎛, the deposition rate is 1 ~ 25㎛ / min.
