Description

TECHNICAL FIELD

[0001] The present disclosure relates to a wideband capacitor, and more particularly, to a wideband capacitor for constructing a high-speed communication network. BACKGROUND

[0002] A conventional wideband capacitor is constructed by stacking a plurality of electrode units, each of which is composed of a main electrode having an extension arm formed on a lateral portion of one side of the main electrode and a C-type electrode surrounding the other side of the main electrode. The conventional wideband capacitor achieves a wideband characteristic by increasing a capacitance by forming a primary capacitance through overlapping between the main electrodes and a secondary capacitance between the C-type electrodes and the main electrodes.

[0003] However, the conventional wideband capacitor has a problem in that it is difficult to change a capacitance value since an area of the main electrode can be changed within a limited range due to the extension arm and the side to which the main electrode is connected and the C-type electrode. SUMMARY

The dielectric has a laminate disposed therein, and the laminate has a plurality of internal electrodes stacked thereon. The dielectric has an upper surface, a lower surface, a first side surface, a second side surface, a third side surface, and a fourth side surface. The first external electrode is disposed on the first side surface of the dielectric and extends to the upper surface, the lower surface, the third side surface, and the fourth side surface of the dielectric and is disposed on the dielectric. The second external electrode is disposed on the second side surface of the dielectric and extends to the upper surface, the lower surface, the third side surface, and the fourth side surface of the dielectric and is disposed on the dielectric. The first floating electrode is disposed above the laminate. The second floating electrode is disposed below the laminate. The third floating electrode is disposed on one side of the laminate. The fourth floating electrode is disposed on the other side of the laminate facing the one side.

[0008] The first floating electrode can overlap a portion of the first external electrode disposed on the upper surface of the dielectric and a portion of the second external electrode disposed on the upper surface of the dielectric. The second floating electrode can overlap a portion of the first external electrode disposed on the lower surface of the dielectric and a portion of the second external electrode disposed on the lower surface of the dielectric. The third floating electrode can overlap a portion of the first external electrode and a portion of the second external electrode disposed on the third side surface of the dielectric. The fourth floating electrode can overlap a portion of the first external electrode and a portion of the second external electrode disposed on the fourth side surface of the dielectric.

[0009] The plurality of internal electrodes can include a plurality of first internal electrodes and a plurality of second internal electrodes. The plurality of first internal electrodes and the plurality of second internal electrodes can be alternately disposed. A first side of the plurality of first internal electrodes can be connected to the first external electrode on the first side surface of the dielectric, and a second side of the plurality of first internal electrodes facing the first side can be spaced apart from the second external electrode disposed on the second side surface of the dielectric. A first side of the plurality of second internal electrodes can be connected to the second external electrode on the second side surface of the dielectric, and a second side of the plurality of second internal electrodes facing the first side can be spaced apart from the first external electrode disposed on the first side surface of the dielectric.

[0010] The laminated body can be disposed in an area surrounded by the first floating electrode, the second floating electrode, the third floating electrode, and the fourth floating electrode.

[0011] A first side of the first floating electrode can be connected to a first side of the third floating electrode. A second side of the first floating electrode can be connected to a first side of the fourth floating electrode. A first side of the second floating electrode can be connected to a second side of the third floating electrode. A second side of the second floating electrode can be connected to a second side of the fourth floating electrode.

[0012] A first side of the first floating electrode can be connected to a first side of the third floating electrode. A first side of the second floating electrode can be spaced apart from a second side of the third floating electrode. A first side of the fourth floating electrode can be spaced apart from a second side of the first floating electrode. A second side of the second floating electrode can be connected to a second side of the fourth floating electrode.

[0013] The first floating electrode and the second floating electrode can be disposed in parallel with the plurality of internal electrodes. The third floating electrode and the fourth floating electrode can be disposed in parallel with a virtual plane orthogonal to the plurality of internal electrodes.

[0014] The first floating electrode can be disposed adjacent to the upper surface of the dielectric. The second floating electrode can be disposed adjacent to the lower surface of the dielectric. The third floating electrode can be disposed adjacent to the third side surface of the dielectric. The fourth floating electrode can be disposed adjacent to the fourth side surface of the dielectric.

[0015] Advantageous Effects

[0016] The wideband capacitor according to the disclosure has the effect that, because the floating electrodes, which are disposed perpendicular to the internal electrodes, are disposed at the left and right sides of the internal electrodes, the wideband capacitor according to the disclosure can increase the current loop effect and / or the parasitic capacitance effect compared to a structure in which electrodes parallel to the internal electrodes are disposed at the left and right sides of the internal electrodes.

[0017] In other words, because a gap is formed between the electrodes parallel to the internal electrodes (i.e., between the layers), the wideband capacitor having a structure in which electrodes parallel to the internal electrodes are disposed at the left and right sides of the internal electrodes has electric field leakage, etc. In contrast, because the floating electrodes, which are disposed perpendicular to the internal electrodes, are disposed at the left and right sides of the internal electrodes, and the gap between the layers is relatively small, the wideband capacitor according to the embodiment of the disclosure can increase the current loop effect and / or the parasitic capacitance effect.

[0018] In addition, the wideband capacitor has the effect that, compared to a structure in which electrodes parallel to the internal electrodes are disposed at the left and right sides of the internal electrodes, because the floating electrodes, which are disposed perpendicular to the internal electrodes, are disposed at the left and right sides of the internal electrodes and occupy a relatively small space, the area of the capacitance part can be relatively increased.

[0019] In addition, the wideband capacitor has the effect that, by disposing the floating electrodes, which are disposed perpendicular to the internal electrodes, at the left and right sides of the internal electrodes, the area of the capacitance part is relatively increased, so that a relatively high capacity can be implemented in the same size.

[0020] Therefore, the wideband capacitor has constant frequency performance, and can also be manufactured to be very small in size and high in capacity. BRIEF DESCRIPTION OF DRAWINGS

Also, in describing the disclosure, when it is determined that a detailed description of a related well-known configuration or function can obscure the gist of the disclosure, a detailed description thereof will be omitted.

[0027] First, in adding reference numerals to elements of each drawing, it should be noted that even if the same elements are shown in different drawings, they have the same reference numerals as much as possible.

[0028] Also, in describing the embodiments of the disclosure, when it is determined that a detailed description of a related well-known configuration or function can obscure the subject matter of the disclosure, a detailed description thereof will be omitted.

[0029] Reference Figures 1 to 3 The wideband capacitor according to the embodiments of the disclosure includes a dielectric 100, a first external electrode 220, a second external electrode 240, a plurality of first internal electrodes 320, a plurality of second internal electrodes 340, a first floating electrode 410, a second floating electrode 420, a third floating electrode 430, and a fourth floating electrode 440.

[0030] The dielectric 100 has an upper surface, a lower surface, a first side surface, a second side surface, a third side surface, and a fourth side surface. In this case, the upper surface faces the lower surface, the first side surface faces the second side surface, and the third side surface faces the fourth side surface. Thus, taking the dielectric 100 as a rectangular parallelepiped having an upper surface, a lower surface, a first side surface, a second side surface facing the first side surface, a third side surface, and a fourth side surface facing the third side surface, for example. In this case, the dielectric 100 can be constructed of a laminate on which a plurality of dielectric sheets on which internal electrodes are formed are stacked.

[0031] The first external electrode 220 is an electrode disposed on the first side surface of the dielectric 100. The first external electrode 220 can be formed by extending from the upper surface, the lower surface, the third side surface, and the fourth side surface of the dielectric 100 in the direction of the second external electrode 240.

[0032] The second external electrode 240 is an electrode disposed on the second side surface of the dielectric 100. The second external electrode 240 can be formed by extending from the upper surface, the lower surface, the third side surface, and the fourth side surface of the dielectric 100 in the direction of the first external electrode 220.

[0033] In this case, the first external electrode 220 and the second external electrode 240 can be spaced apart from each other at a predetermined interval G and formed to face each other on the upper surface, the lower surface, the third side surface, and the fourth side surface of the dielectric 100.

[0034] The plurality of internal electrodes are sequentially stacked to constitute a laminate disposed within the dielectric 100. The plurality of internal electrodes include a plurality of first internal electrodes 320 and a plurality of second internal electrodes 340. The plurality of first internal electrodes 320 and the plurality of second internal electrodes 340 are alternately disposed (stacked).

[0035] The first side of the plurality of first internal electrodes 320 is connected to the first external electrode 220 on the first side surface of the dielectric 100. The second side of the plurality of first internal electrodes 320 facing the first side is spaced apart from the second external electrode 240 disposed on the second side surface of the dielectric 100.

[0036] The first internal electrode 320 is composed of a sheet conductor of a rectangular shape. The first internal electrode 320 includes a first side connected to the first external electrode 220, a second side facing the first side, a third side connected to the end portions of the first and second sides on one side thereof, and a fourth side connected to the end portions of the first and second sides on the other side thereof and facing the third side.

[0037] The second internal electrode 340 is composed of a sheet conductor of a rectangular shape. The second internal electrode 340 has a first side connected to the second external electrode 240, a second side facing the first side, a third side connected to the end portions of the first and second sides on one side thereof, and a fourth side connected to the end portions of the first and second sides on the other side thereof and facing the third side.

[0038] The plurality of first internal electrodes 320 and the plurality of second internal electrodes 340 are alternately stacked. In this case, an example in which a dielectric sheet on which the first internal electrode 320 is formed and a dielectric sheet on which the second internal electrode 340 is formed are alternately stacked to form the laminate is taken.

[0039] The first side of the plurality of first internal electrodes 320 is connected to the first external electrode 220 on the first side surface of the dielectric 100. The second side of the plurality of first internal electrodes 320 facing the first side is spaced apart from the second external electrode 240 disposed on the second side surface of the dielectric 100. The first side of the plurality of second internal electrodes 340 is connected to the second external electrode 240 on the second side surface of the dielectric 100. The second side of the plurality of second internal electrodes 340 facing the first side is spaced apart from the first external electrode 220 disposed on the first side surface of the dielectric 100.

[0040] Accordingly, the plurality of first internal electrodes 320 and the plurality of second internal electrodes 340 form overlapping regions within the dielectric 100 and form capacitances in the overlapping regions.

[0041] Meanwhile, the laminate in which the plurality of internal electrodes are stacked and constructed is disposed within the dielectric 100 and is disposed in a region surrounded by the first floating electrode 410, the second floating electrode 420, the third floating electrode 430, and the fourth floating electrode 440. In this case, the overlapping regions formed by the plurality of internal electrodes are disposed in the region surrounded by the first floating electrode 410, the second floating electrode 420, the third floating electrode 430, and the fourth floating electrode 440.

[0042] The first floating electrode 410 is composed of a sheet-shaped conductor and is disposed adjacent to the upper surface of the dielectric 100. The first floating electrode 410 is disposed above the laminate in which the plurality of internal electrodes are stacked. The first floating electrode 410 is spaced apart from the internal electrodes disposed on the upper surface of the laminate at a predetermined interval, and a dielectric layer is interposed between the first floating electrode and the internal electrodes.

[0043] The first floating electrode 410 overlaps the first external electrode 220 and the second external electrode 240. That is, the first floating electrode 410 overlaps a portion of the first external electrode 220 disposed on the upper surface of the dielectric 100 and a portion of the second external electrode 240 disposed on the upper surface of the dielectric 100. Accordingly, the wideband capacitor forms capacitances between the first external electrode 220 and the second external electrode 240 and the first floating electrode 410.

[0044] The first floating electrode 410 is disposed in parallel with the plurality of internal electrodes. That is, the first floating electrode 410 is disposed between the upper surface of the dielectric 100 and the internal electrode disposed at the top among the plurality of internal electrodes and can be disposed in parallel with the internal electrodes.

[0045] Accordingly, the wideband capacitor forms capacitances between the first floating electrode 410 and the internal electrodes.

[0046] The second floating electrode 420 is composed of a sheet conductor, and is disposed adjacent to the lower surface of the dielectric 100. The second floating electrode 420 is disposed below the laminate on which the plurality of internal electrodes are stacked. The second floating electrode 420 is spaced apart from the internal electrodes disposed on the lower surface of the laminate at a predetermined interval, and a dielectric layer is interposed between the second floating electrode and the internal electrodes.

[0047] The second floating electrode 420 overlaps the first external electrode 220 and the second external electrode 240. That is, the second floating electrode 420 overlaps a portion of the first external electrode 220 disposed on the lower surface of the dielectric 100 and a portion of the second external electrode 240 disposed on the lower surface of the dielectric 100. Accordingly, the wideband capacitor forms a capacitance between the first external electrode 220 and the second external electrode 240 and the second floating electrode 420.

[0048] The second floating electrode 420 is disposed in parallel with the plurality of internal electrodes. That is, the second floating electrode 420 is disposed between the lower surface of the dielectric 100 and the internal electrode disposed at the bottom among the plurality of internal electrodes, and can be disposed in parallel with the internal electrodes. Accordingly, the wideband capacitor forms a capacitance between the second floating electrode 410 and the internal electrodes.

[0049] The third floating electrode 430 is composed of a sheet conductor, and is disposed adjacent to the third side surface of the dielectric 100. The third floating electrode 430 is disposed at one side of the laminate on which the plurality of internal electrodes are stacked. The third floating electrode 430 is spaced apart from the third side of the plurality of internal electrodes at a predetermined interval, and a dielectric layer is interposed between the third floating electrode and the internal electrodes.

[0050] The third floating electrode 430 overlaps the first external electrode 220 and the second external electrode 240. That is, the third floating electrode 430 overlaps a portion of the first external electrode 220 disposed on the third side surface of the dielectric 100 and a portion of the second external electrode 240 disposed on the third side surface of the dielectric 100. Accordingly, the wideband capacitor forms a capacitance between the first external electrode 220 and the second external electrode 240 and the third floating electrode 430.

[0051] The third floating electrode 430 is disposed in parallel with the third side of the plurality of internal electrodes (or the third side surface of the dielectric 100). The third floating electrode 430 is disposed between the third side of the plurality of internal electrodes and the third side surface of the dielectric 100. The third floating electrode 430 can be disposed in parallel with a virtual plane orthogonal to the plurality of internal electrodes (or the laminate). Accordingly, the wideband capacitor forms a capacitance between the third floating electrode 430 and the internal electrodes.

[0052] The fourth floating electrode 440 is composed of a sheet conductor, and is disposed adjacent to the fourth side surface of the dielectric 100. The fourth floating electrode 440 is disposed on the other side of the laminate in which the plurality of internal electrodes are stacked. The fourth floating electrode 440 is spaced apart from the fourth side of the plurality of internal electrodes at a predetermined interval, and a dielectric layer is interposed between the fourth floating electrode and the internal electrodes.

[0053] The fourth floating electrode 440 overlaps the first external electrode 220 and the second external electrode 240. That is, the fourth floating electrode 440 overlaps a portion of the first external electrode 220 disposed on the fourth side surface of the dielectric 100 and a portion of the second external electrode 240 disposed on the fourth side surface of the dielectric 100. Accordingly, the wideband capacitor forms a capacitance between the first external electrode 220 and the second external electrode 240 and the fourth floating electrode 440.

[0054] The fourth floating electrode 440 is disposed in parallel with the fourth side of the plurality of internal electrodes (or the fourth side surface of the dielectric 100). The fourth floating electrode 440 is disposed between the fourth side of the plurality of internal electrodes and the fourth side surface of the dielectric 100. The fourth floating electrode 440 can be disposed in parallel with a virtual plane orthogonal to the plurality of internal electrodes (or the laminate). Accordingly, the wideband capacitor forms a capacitance between the fourth floating electrode 440 and the internal electrodes.

[0055] Referring to Figure 4 , the first floating electrode 410 to the fourth floating electrode 440 are disposed spaced apart from each other. That is, the first side of the first floating electrode 410 is spaced apart from the first side of the third floating electrode 430. The second side of the first floating electrode 410 is spaced apart from the first side of the fourth floating electrode 440. The first side of the second floating electrode 420 is spaced apart from the second side of the third floating electrode 430. The second side of the second floating electrode 420 is spaced apart from the second side of the fourth floating electrode 440.

[0056] The third floating electrode and the fourth floating electrode can be implemented by the following processes. Hereinafter, the laminate on which the dielectric sheet on which the internal electrodes are stacked has been stacked.

[0057] For example, the third floating electrode and the fourth floating electrode are implemented by a first process of forming a first dielectric layer on a side surface of the laminate through a dielectric printing process or a dielectric sheet bonding process, a second process of forming an electrode on a surface of the first dielectric layer by printing a metal on the first dielectric layer, and a third process of forming a second dielectric layer on the surface of the electrode and the first dielectric layer through a dielectric printing process or a dielectric sheet bonding process.

[0058] Further, for example, the third and fourth floating electrodes can be implemented by a first process of forming the electrodes on a dielectric sheet of the side surface through a printing process, a second process of joining the dielectric sheet on which the electrodes have been formed to the side surface of the stack, and a third process of forming a second dielectric layer on the surface of the electrodes and the dielectric sheet through a dielectric printing process or a dielectric sheet joining process.

[0059] Further, for example, the third and fourth floating electrodes can be implemented by a first process of forming the electrodes on a dielectric sheet of the side surface through a printing process, a second process of joining the dielectric sheet on which the electrodes have been formed to the side surface of the stack, and a third process of forming a second dielectric layer on the surface of the electrodes and the dielectric sheet through a dielectric printing process or a dielectric sheet joining process.

[0060] In this case, the dielectric layer printed on or joined to the side surface of the stack can prevent defects occurring in the capacitor due to a difference between densities by making the density uniform through a warm isostatic press (WIP) process or the like.

[0061] Two or more of the first floating electrodes 410 to the fourth floating electrodes 440 can be connected to optimize the manufacturing process conditions and frequency characteristics of the capacitor. In this case, two electrodes adjacent to each other among the first to fourth floating electrodes 410 and 430 are connected.

[0062] Referring to Figure 5 The first to fourth floating electrodes 410 and 440 can be connected to form a rectangular parallelepiped tubular pipe-type floating electrode 450.

[0063] For example, a first side of the first floating electrode 410 can be connected to a first side of the third floating electrode 430. A second side of the first floating electrode 410 can be connected to a first side of the fourth floating electrode 440. A first side of the second floating electrode 420 can be connected to a second side of the third floating electrode 430. A second side of the second floating electrode 420 can be connected to a second side of the fourth floating electrode 440.

[0064] Accordingly, the first to fourth floating electrodes 410 and 440 form the rectangular parallelepiped tubular pipe-type floating electrode 450 that accommodates the stack. In this case, a portion of the stack is accommodated in an inner region of the pipe-type floating electrode 450, and an overlapping region formed by the plurality of internal electrodes is accommodated in the inner region.

[0065] Referring to Figure 6, the first to fourth floating electrodes 410 to 440 can form a cover-shaped floating electrode 460 and a sheet-shaped floating electrode 470. That is, among the first to fourth floating electrodes 410 to 440, three floating electrodes adjacent to each other are connected to form the cover-shaped floating electrode 460 having a quadrangular cross section, one side of which is open. In this case, the remaining one floating electrode forms the sheet-shaped floating electrode 470 corresponding to the open side of the quadrangular shape.

[0066] For example, the first side of the first floating electrode 410 is connected to the first side of the third floating electrode 430. The second side of the first floating electrode 410 is connected to the first side of the fourth floating electrode 440. Accordingly, the first floating electrode 410, the third floating electrode 430, and the fourth floating electrode 440 form the cover-shaped floating electrode 460 having a quadrangular cross section, one side of which is open in the direction of the second floating electrode 420. The second floating electrode 420 is disposed between the second side of the third floating electrode 430 and the second side of the fourth floating electrode 440, and forms the sheet-shaped floating electrode 480 which is spaced apart from the third floating electrode 430 and the fourth floating electrode 440 at a predetermined interval.

[0067] Referring to Figure 7 , two floating electrodes adjacent to each other among the first to fourth floating electrodes 410 to 440 are connected to form two curved floating electrodes spaced apart from each other. In this case, the first to fourth floating electrodes 410 to 440 can form a first curved floating electrode 480 and a second curved floating electrode 490 spaced apart from each other.

[0068] For example, the first side of the first floating electrode 410 is connected to the first side of the third floating electrode 430, thereby forming the first curved floating electrode 480. The second side of the second floating electrode 420 is connected to the second side of the fourth floating electrode 440, thereby forming the second curved floating electrode 490.

[0069] The first side of the second floating electrode 420 is spaced apart from the second side of the third floating electrode 430. The first side of the fourth floating electrode 440 is spaced apart from the second side of the first floating electrode 410. Accordingly, the first curved floating electrode 480 and the second curved floating electrode 490 are spaced apart from each other and form a rectangular parallelepiped tube in which the gap between the first and fourth plates and the gap between the second and third plates are opened.

[0070] As described above, although the preferred embodiments according to the present disclosure have been described, it should be understood that various changes can be made in form and details, and examples of various changes and examples of modifications can be practiced by those skilled in the art without departing from the claims of the present disclosure.
