(Multiple Split Ring Resonator Using Metamaterial Having Negative Permeability)

The present invention relates to a multiple-split ring resonator using a meta-material having negative magnetic permeability and, more particularly, to a multi-split ring resonator having ring structures of different lengths having the same center, A resonance pattern portion having a negative permeability characteristic at the central portion of the ring resonance pattern portion formed of a pattern and formed of a metal conductor pattern for adjusting the size of the resonator is formed to provide excellent resonance characteristics and at the same time, The present invention relates to a multi-split ring resonator using a metamaterial having magnetic permeability characteristics.

Recently, metamaterials have been actively studied due to their ability to control electromagnetic characteristics with new methods. In general, a metamaterial is an artificially designed material in which the electromagnetic properties of the material are determined by the structure rather than the chemical composition of the constituent material.

One of the typical properties of a metamaterial is that it indicates a negative permeability, and a metamaterial having a negative permeability is called a new material or structure because it can arbitrarily control the size of a resonator by using characteristics such as a negative permeability have.

As a typical technique having such a negative magnetic permeability characteristic, there is a split-ring resonator (SRR) which is excellent in resonance characteristics and is easy to perform electromagnetic control.

In order to use the split-ring resonator in a wireless communication system, research and development have been actively carried out to reduce the size while improving the performance.

Generally, the resonance characteristic, which is a measure of frequency selection, is important for a resonator mainly used in a wireless communication system, and the signal response performance of the wireless communication system depends on such resonance characteristics. In recent years, dielectric resonators have been used in order to secure excellent resonance characteristics. However, dielectric resonators have a three-dimensional structure unlike a split-ring resonator in that they have been used for oscillators, antennas, filters, and duplexers. Therefore, it is difficult to integrate the substrate with the non-process substrate and there is a problem that the volume is large.

Therefore, a split-ring resonator having a planar structure is suitable for satisfying integration and miniaturization with a non-process substrate.

As shown in the figure, a conventional split-ring resonator includes a metal line 11 and a split gap 12 as a resonator having a partially cut ring structure formed on a substrate 1 in the form of a loop Metal conductor pattern 10. At this time, as shown in the equivalent circuit, the metal line 11 serves as an inductor and the split gap 12 serves as a capacitor to induce resonance of an incident signal. If one value can be changed, the resonant frequency of the split-ring resonator can be changed.

However, in the conventional split-ring resonator, a method of widening the width W of the metal wire 11 is used to increase the resonance characteristics. However, when the width W of the metal wire 11 is widened, .

Conventionally, there is a multi-structure split-ring resonator having a concentric structure in order to overcome such a problem.

Figs. 3 to 4 are views showing a conventional two-stage split-ring resonator and a three-stage split-ring resonator.

As shown in the figure, a conventional multi-structure split-ring resonator has a structure in which metal conductor patterns 21, 22, 31, 32, 33 forming two or three split-ring resonators are concentric with each other And are formed in such a manner that the surfaces opposite to each other are successively alternately opposed to each other at a predetermined interval.

Here, the resonant characteristics of the conventional two-stage structure split ring resonator are improved compared to the split-ring resonator of FIG. 1 because coupling coupling occurs between the metal conductor patterns 21 and 22, , 22), there is a limitation in reducing the overall size of the resonator.

In addition, although the conventional three-stage structure split-ring resonator can maintain an excellent resonance characteristic as compared with the two-stage split-ring resonator of FIG. 3, there is a problem that the size of the resonator increases in order to maintain such excellent resonance characteristics there was.

Accordingly, there is a serious demand for a realistic and highly utilizable technique capable of providing a split-ring resonator capable of providing excellent resonance characteristics and satisfying miniaturization at the same time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

5 is a view showing a multiple split ring resonator using a meta-material having a negative permeability characteristic according to an embodiment of the present invention.

As shown in the drawing, a multiple-split ring resonator using a meta-material having a negative permeability characteristic according to an embodiment of the present invention includes a substrate 100, a ring resonance pattern portion 200, And a pattern unit (300).

More specifically, the substrate 100 corresponds to a medium of a RF signal as a dielectric substrate having a predetermined dielectric constant, and the substrate 100 according to an embodiment of the present invention is used for a general purpose having a dielectric constant of 2.54 and a height of 0.54 mm A multi-split ring resonator according to the present invention can be mass-produced at a low cost. In addition to the glass epoxy substrate (FR-4), if the electrical characteristics close to the insulator are satisfied Various substrates can be used as needed.

The ring resonance pattern portion 200 is formed on the substrate 100 by arranging a plurality of metal conductor patterns having ring structures of different lengths concentrically and spaced apart at regular intervals. Here, the metal conductor pattern may be formed using a metal having excellent conductivity including gold (Au), copper (Cu), and aluminum (Al).

In the embodiment of the present invention, the ring resonance pattern portion 200 includes a first pattern 210 (see FIG. 2) formed in a first direction while a part of a metal conductor pattern, which is located at the innermost corner of the plurality of metal conductor patterns, A second pattern 220 located outside the first pattern 210 and partially formed of a ring-shaped metal conductor pattern while being cut in a second direction; and a third pattern 220 formed on the outermost one of the plurality of metal conductor patterns And a third pattern 230 in which a part of the metal conductor pattern formed by the ring structure is cut in the third direction.

In addition, in the embodiment of the present invention, the first to third patterns constituting the ring resonance pattern unit 200 are arranged in a rectangular ring structure spaced apart at regular intervals from the four corners of the substrate 100 And a part of the metal conductor pattern is cut to form split gaps 211, 221 and 231, respectively. Here, the split gaps 211, 221, and 231 may have different sizes and may be located in different directions. In the embodiment of the present invention, as shown in the drawing, the split gaps 211, 221, And the first direction is formed to be parallel to the third direction at the same time as facing the second direction, and the first pattern to the third pattern are alternately and continuously alternated with each other.

In the present invention, the shapes of the first to third patterns constituting the ring resonance pattern unit 200 are not limited to the rectangular or rectangular shape. However, in the embodiment of the present invention, Therefore, when a resonance frequency of a low frequency band with a relatively low frequency band is required in the same substrate size, a longer line length can be secured compared with a circular shape, which is preferable for miniaturizing the size of the resonator.

Among the plurality of metal conductor patterns having ring structures of different lengths constituting the ring resonance pattern part 200, adjacent metal conductor patterns are coupled to each other and coupled to each other. As shown in the drawing, A voltage having a polarity and an electric field are generated In this case, the induction current flows while the magnetic field is generated.

In this case, the induced current flows with a polarity on the line, and a potential difference occurs because the coupling structure between the lines has a polarity due to the occupied capacitance. Therefore, in the split ring resonator according to the present invention, the external magnetic field energy is generated in a direction in which the induced current interferes, so that the magnetic permeability in the resonance frequency band is opposite to that of the resonance frequency, . That is, since the split ring resonator according to the present invention operates at a negative magnetic permeability value in the resonance frequency band, the characteristics of the meta material can be satisfied, and the split ring resonator using the meta- Since the original resonator phase is operated at a linear slope of -90 ° due to the opposite flow direction, the resonator having a metamaterial characteristic operates at a nonlinear slope of 90 °, resulting in a region that can not operate in a general material As a result, since the size and frequency of the resonator are inversely proportional to each other, the splitting ring resonator according to the present invention can be applied to a technique of reducing the size of the resonator regardless of the wavelength required in the resonance frequency band .

The extended resonance pattern part 300 according to the present invention includes a plurality of metal conductor patterns 300a and 300b formed on a surface of the first pattern 210 corresponding to a metal conductor pattern, And one end of which is electrically connected to the extended patch portion 310 and the other end of which is electrically connected to a portion of the first pattern 210. The extended pattern portion 310 is formed on the first pattern 210, And a standard line pattern unit 320. [ The extended line pattern portion 320 extends along the periphery of the extended patch portion 310 of the rectangular shape except for the direction in which the split gap 211 of the first pattern 210 is formed, The extended resonance pattern portion 300 includes three extended line pattern portions 320, as shown in the drawing of the embodiment of the present invention.

In addition, the extended resonance patch unit 310 adjusts the frequency band by adjusting the length L1 of the extended line pattern portion and the circumferential length L2 of the extended patch portion. At this time, The length L1 of the deadline pattern portion and the circumferential length L2 of the extended patch portion are inversely proportional to each other.

As described above, since the multiple band split ring resonator using the meta-material having the negative permeability characteristic according to the embodiment of the present invention and the frequency band can be adjusted by adjusting the size of the extended resonance pattern portion 300, The size of the resonator can be reduced.

Therefore, even if the size of the ring resonance pattern portion 200 is reduced, the extended resonance pattern portion 300, which constitutes the extended resonance pattern portion 300, The operating frequency band of the resonator can be maintained by adjusting the size of the dead patch portion 310 and the length of the extended line pattern portion 320.

That is, when the entire line constituting the resonator is reduced, the metal conductor pattern of the ring resonance pattern unit 200 serves as an inductor, so that the inductance is reduced and the resonance frequency is increased and changed.
