1 is a top view of a magnet type combo antenna module 100 according to a first embodiment of the present invention, and FIG. 2 is a view showing a bottom surface viewed from the top direction, more specifically, a base film 10 from the top surface. It is a view showing a view through the base film 10 after removing the components disposed on the upper surface.

The combo antenna module 100 according to the first embodiment of the present invention may include a base film 10, a first radiation pattern 20 and a second radiation pattern 30, and achieves other objects of the present invention. It goes without saying that typical components required for this may be further included, for example, a magnetic sheet (not shown) and a graphite sheet (not shown).

The base film 10 is a component of the basic body of the combo antenna module 100 according to an embodiment of the present invention, and is a film having flexibility and insulation, more specifically, a polyimide film, a polyester film, a polypara It can be implemented with a vinyl acid film, a polyethylene phthalate film, a thermoplastic polyurethane film, and the like.

Such a base film 10 can be implemented in various shapes as well as the shape shown in FIG. 1, and the shape of the base film 10 is mounted with the combo antenna module 100 according to an embodiment of the present invention. It may vary according to the internal component mounting design of the mobile communication device (not shown).

The first radiation pattern 20 includes the 1-1st radiation pattern 20-1 and the 1-2nd radiation pattern 20-2, and will be described below from the 1-1st radiation pattern 20-1. do.

The 1-1st radiation pattern 20-1 is disposed on one surface of the base film 10, and includes one or more first gaps (Gap, G1) spaced apart by a predetermined interval therein.

Here, one surface of the base film 10 means either the upper or lower surface of the base film 10, and when one surface is the upper surface, the other surface becomes the lower surface, and when one surface is the lower surface, the other surface becomes the upper surface, Referring to FIG. 1, the description will be continued based on the fact that one surface is the upper surface and the other surface is the lower surface with reference to FIG. 2.

The 1-1 radiation pattern 20-1 is formed on one surface of the base film 10 by patterning a metal conductive material such as copper or by plating tin, gold, nickel, or solder on the surface of a metal foil containing copper. It can be, more specifically, casting in which the liquid base film 10 is sprayed on the rolled metal foil and thermally cured, laminating in which the base film 10 and the rolled metal foil are placed and thermally compressed, and the base film 10 is applied. Depositing a metal seed layer on and placing the metal foil by placing the base film 10 in the electrolyte dissolved in the metal and flowing electricity

Meanwhile, referring to FIG. 1 , it can be seen that the 1-1 radiation pattern 20-1 disposed on one surface of the base film 10 is cut off at the 2 o'clock direction, and the cut off part is in the first gap G1 ), and accordingly, the first gap G1 can be seen as a region spaced apart by a predetermined interval from the inside of the 1-1 radiation pattern 20-1, and the 1-1 radiation pattern 20-1 has a first One or more gaps G1 may be included.

Referring to FIG. 3 showing an enlarged view of the first gap G1 , the innermost radiation pattern of the 1-1 radiation pattern 20-1 is disposed to face outward across the other radiation patterns, which will be described later. Apart from the fact that the 2-1st radiation pattern 20-1 is disposed, it can be confirmed that one or more vias are shown on both sides of the first gap G1, and the corresponding vias are the first vias. (V1), more specifically, the 1-1 via V1-1, even if the 1-1 radiation pattern is disconnected from the first gap G1 through one or more 1-1 vias V1-1. It may be electrically connected to the first and second radiation patterns 20-2 disposed on the other surface of the base film 10.

Meanwhile, referring to FIG. 1 again separately, it can be confirmed that one or more vias are also shown in the 7 o'clock direction of the 1-1 radiation pattern 20-1, and the vias are also the first vias V1, More specifically, it is the 1-2nd via V1-2, which is the 1-2nd radiation pattern 20-2 in the second gap G2 included in the 1-2nd radiation pattern 20-1 to be described later. and the 1-1 radiation pattern 20-1 electrically connected to each other, a detailed description of this will be described later.

The 1-1 radiation pattern 20-1 described above is a WPC pattern in charge of the wireless charging function, and accordingly, the coil-type radiation pattern is arranged in a form wound a plurality of times to form an empty area E in the inward direction. will do

On the other hand, since the 1-1 radiation pattern 20-1 is a WPC pattern, a length value of a certain level or more is required, and the 1-1 radiation pattern 20-1 that can be disposed on one surface of the base film 10 Since there is a limit to the length even if it is disposed in the form of winding a plurality of times, it is electrically connected to the 1-1 radiation pattern 20-1 on the other side of the base film 10 through one or more first vias V1, As a bar, a radiation pattern that can satisfy the length value of the WPC pattern is disposed, and the first-second radiation pattern 20-2 is that.

The 1-2nd radiation pattern 20-2 is disposed on the other surface of the base film 10, and is connected to the 1-1st radiation pattern 20-1 through one or more first vias V1. It includes at least one second gap G2 that is a region spaced apart by a predetermined interval.

Here, since the 1-2 radiation pattern 20-2 is disposed on the other surface of the base film 10, it can be regarded as being disposed on the opposite surface to the surface on which the 1-1 radiation pattern 20-1 is disposed. Referring to FIG. 2 , it can be seen that the first and second radiation patterns 20 - 2 are disposed on the lower surface of the base film 10 .

Meanwhile, like the 1-1st radiation pattern 20-1, the 1-2nd radiation pattern 20-2 is also patterned with a metal conductive material such as copper or tin, gold, nickel or copper on the surface of a metal foil containing copper. Solder or the like may be plated to be disposed on one surface of the base film 10, and it will be understood that known methods such as casting, laminating, and electroplating can be used.

In addition, referring to FIG. 2 , it can be seen that the 1-2 radiation patterns 20-2 disposed on the other surface of the base film 10 are broken at the 7 o'clock direction, and the broken part is the second gap (G2 ), and accordingly, the second gap G2 can be viewed as a region spaced apart by a predetermined interval from the inside of the 1-2 radiation pattern 20-2, and the 1-2 radiation pattern 20-2 is the second One or more gaps G2 may be included.

Referring to FIG. 4 showing an enlarged second gap G2 , apart from the fact that a 2-2 radiation pattern 20-2 to be described later is disposed in the second gap G2, the second gap G2 It can be seen that one or more vias are shown on both sides of ), and the corresponding vias are first vias V1, more specifically 1-2 vias V1-2, and one or more 1- Through the 2 vias V1-2, even if the 1-2nd radiation pattern is disconnected from the second gap G2, it can be electrically connected to the 1-1st radiation pattern 20-1 disposed on one side of the base film 10. can

Meanwhile, referring to FIG. 2 again separately from this, it can be seen that one or more vias are also shown in the 2 o'clock direction of the 1-2 radiation pattern 20-2, and the vias are also the first vias V1, More specifically, it is the 1-1st via V1-1, which is the 1-1st radiation pattern 20-1 in the first gap G1 included in the 1-1st radiation pattern 20-1 described above. and serves to electrically connect the first and second radiation patterns 20-2.

The 1-2 radiation pattern 20-2 described above is also a WPC pattern responsible for the wireless charging function, and accordingly, the coil-type radiation pattern is arranged in a form wound multiple times to form an empty area E in the inward direction. The length value of the WPC pattern may be satisfied by electrically connecting to the 1-1 radiation pattern 20-1 disposed on one surface of the base film 10 through the first via V1.

This can be checked by overlapping FIGS. 1 and 2. Although not separately shown due to the complexity of the drawings, assuming a situation in which FIGS. 1 and 2 are overlapped, the base film 10 disposed on one side The 1-1 radiation pattern 20-1 and the 1-2 radiation pattern 20-2 disposed on the other side are one despite the existence of the first gap G1 and the second gap G2 cut in the middle. If the radiation patterns electrically connected through the above first via V1 and wound multiple times are unwound, it will be easy to predict that they become one long radiation pattern.

The second radiation pattern 30 includes a 2-1 radiation pattern 30-1 and a 2-2 radiation pattern 30-2, and will be described below from the 2-1 radiation pattern 30-1. do.

The 2-1st radiation pattern 30-1 is disposed on one surface of the base film 10 so as not to overlap with the 1-1st radiation pattern 20-1.

Here, the non-overlapping arrangement means that the 2-1 radiation pattern 30-1 does not overlap with the 1-1 radiation pattern 20-1 and the 1-1 radiation pattern 20-1 is not disposed. This means that the radiation patterns are disposed only in areas where the radiation patterns are overlapped, which has a fatal effect on the performance of each radiation pattern.

In order to prevent this, the 2-1 radiation pattern 30-1 is spaced apart from the 1-1 radiation pattern 20-1 by a predetermined distance, and the 1-1 radiation pattern 20-1 is disposed inside the base film. The overlapping situation may be avoided by disposing in a form surrounding the outer circumference of (10), but in this case, the area for disposing the 2-1 radiation pattern 30-1 and the 1-1 radiation pattern 20-1 1) There is a problem in that the size of the entire antenna module increases because the area of the base film 10 is widened because the area where the area is disposed is separately required.

The magnet type combo antenna module 100 according to the first embodiment of the present invention is a 2-1 radiation pattern 30-1 and a 1-1 radiation pattern in order to dramatically reduce the size of the entire antenna module in this situation. (20-1) does not overlap, but adopts a method of sharing a part of the area where each radiation pattern is arranged.

Prior to this description, the 2-1 reflective pattern 30-1 is an NFC pattern responsible for a non-contact short-range communication function, and accordingly, the coil-type radiation pattern is smaller than the first radiation pattern 20, which is the WPC pattern described above. It is premised that it is arranged in a rolled form.

A part of the 2-1st radiation pattern 30-1 is disposed in the first gap G1.

Here, a part of the 2-1st radiation pattern 30-1 is disposed in the first gap G1 means that a part of the 2-1st radiation pattern 30-1 is disposed in the first gap G1. -1 radiation pattern 20-1 does not come into direct contact and is disposed so as to enter the entirety, referring again to FIG. 3 described above, a part of the 2-1 radiation pattern 30-1 is part of the first gap ( It can be seen that G1) is disposed to the right of the innermost radiation pattern of the 1-1 radiation pattern 20-1 inside, which indicates that the 2-1 radiation pattern 30-1 is the 1-1 radiation pattern ( 20-1) can be seen as crossing.

On the other hand, apart from a part of the 2-1st radiation pattern 30-1 disposed inside the first gap G1, the other part is disposed outside the 1-1st radiation pattern 20-1. It can be seen from the portion where the terminal and one end are connected to the portion where the portion disposed inside the first gap G1 starts, and the other end of the 2-1 radiation pattern 30-1 is the 1-1 radiation pattern 10 -1) It may be disposed in the empty area E formed in the inward direction, which is the empty area formed in the inner direction of the 1-1st radiation pattern 20-1 of the 2-1st radiation pattern 30-1 ( E) can be seen as being made on one side of the base film (10).

Referring again to FIG. 3 with respect to the other end of the 2-1 radiation pattern 30-1, the other end of the 2-1 radiation pattern 30-1 is the inside of the 1-1 radiation pattern 20-1. Although it is disposed in the empty area E formed in the direction, it can be confirmed that it is disconnected from the second via V2 near the innermost radiation pattern of the 1-1 radiation pattern 20-1. The −1 radiation pattern 30-1 is electrically connected to the 2-2 radiation pattern 30-2 disposed on the other surface of the base film 10 through the second via V2.

Here, the illustration in FIG. 1 of the arrangement position of the second via V2 corresponds to an example, and the second via V2 is an empty area E formed in the inner direction of the 1-1 radiation pattern 20-1. For example, if the second via (V2) is disposed in the center of the empty area (E) formed in the inner direction of the 1-1 radiation pattern (20-1), the second via (V2) It will be said that the -1 radiation pattern 30-1 is also disposed up to the center of the empty area E formed in the inner direction of the 1-1 radiation pattern 20-1.

Furthermore, when the 2-1st radiation pattern 30-1 needs to be placed as long as possible to satisfy the length value required as an NFC pattern, the 2-1st radiation pattern 30-1 is replaced with the 1-1st radiation pattern 30-1. The required length value can be satisfied if the radiation pattern 20-1 is arranged to surround the outer periphery of the blank area E formed in the inward direction or is arranged to be wound multiple times in an inward direction.

This time, the 2-2nd radiation pattern 30-2 will be described.

The 2-2nd radiation pattern 30-2 is disposed on the other surface of the base film 10 and is connected to the 2-1st radiation pattern 30-1 through one or more second vias V2. -2 It is arranged not to overlap with the radiation pattern 20-2.

Here, the term "arranged without overlapping" is the same as the description of the 2-1 radiation pattern 30-1 above, so detailed descriptions are omitted to prevent overlapping descriptions, and the 2-2 radiation pattern 30-2 It is also assumed that the 2-1 radiation pattern 30-1 is an NFC pattern.

A part of the 2-2nd radiation pattern 30-2 is disposed in the second gap G2.

Here, part of the 2-2nd radiation pattern 30-2 is disposed in the second gap G2 means that a part of the 2-2nd radiation pattern 30-2 is disposed inside the second gap G2. -2 It does not directly contact the radiation pattern 20-2 and is disposed so as to enter the entirety. Referring back to FIG. 4 described above, a part of the 2-2 radiation pattern 30-2 is part of the second gap ( G2), it can be seen that the 1-2 radiation pattern 20-2 is disposed on both sides of the inside, which means that the 2-2 radiation pattern 30-2 is the 1-2 radiation pattern 20-2. ) can be seen as crossing.

Meanwhile, apart from the fact that a part of the 2-2nd radiation pattern 30-2 is disposed inside the second gap G2, the remaining part of the 2-1st radiation pattern 30-1 is the first-1 radiation pattern 30-1. It descends to the other surface of the base film 10 through the second via V2 disposed in the empty area E formed in the inward direction of the pattern 20-1 and connects one end of the 2-2nd radiation pattern 30-2. A part of the 1-2 radiation pattern 20-2 from the connected part to the part disposed inside the second gap G2 starts and from the part disposed inside the second gap G2 ends. The other end of the 2-2 radiation pattern 30-2 is disposed in the outer direction of the 1-2 radiation pattern 20-2, which is It can be seen that the 2-2 radiation pattern 30-2 advances from the empty area E formed in the inner direction of the 1-2 radiation pattern 20-2 on the other surface of the base film 10. .

Referring again to FIG. 2 in relation to the other end of the 2-2 radiation pattern 30-2, the 2-2 radiation pattern 30-2 is part of the 1-2 radiation pattern 20-2 inside. It is disposed along the outer edge of the other surface of the base film 10 and is disposed along the outer edge of the base film 10 through the second via V2 in the direction of 2 o'clock outside of the 1-2 radiation pattern 20-2. It can be electrically connected to the 2-1st radiation pattern 30-1 on one side, in this case, the second via disposed in the empty area E formed in the inward direction of the 1-2nd radiation pattern 20-2 (V2) to the 2-1st via (V2-1), and the second via (V2) disposed at the other end of the 2-2nd radiation pattern (30-2) to the 2-2nd via (V2-2) Therefore, one or more second vias V2 may be included.

The second radiation pattern 30 described above, more specifically, the 2-1 radiation pattern 30-1 and the 2-2 radiation pattern 30-2 are the 2-1 radiation patterns on one surface of the base film 10. The pattern 30-1 enters the empty area E formed in the inward direction from the outer direction of the 1-1st radiation pattern 20-1, and the 2-2nd radiation pattern on the other surface of the base film 10. (30-2) has been described based on advancing outward from the empty area E formed in the inward direction of the 1-2 radiation pattern 20-2, but this is only one embodiment, and on the contrary, The 2-2 radiation pattern 30-2 enters the empty area E formed from the outside to the inside of the 1-2 radiation pattern 20-2 on the other surface of the base film 10, and the second- It will be said that the first radiation pattern 30-1 may advance outward from an empty area E formed in the inward direction of the 1-1 radiation pattern 20-1 on one surface of the base film 10.

Furthermore, the 1-1 radiation pattern 20-1 and the 1-2 radiation pattern 20-2 are described based on including one first gap G1 and one second gap G2, respectively. However, since one or more first gaps G1 and one or more second gaps G2 may be included, a plurality may be included. In this case, the 1-1 radiation pattern 20-1 and the 1-2 radiation pattern ( 20-2) may be divided into a plurality of regions, and the entry and exit of the 2-1st radiation pattern 30-1 and the 2-2nd radiation pattern 30-2 are carried out by a plurality of second vias V2. Through this, it may be freely formed on one side or the other side of the base film 10 .

So far, the magnet type combo antenna module 100 according to the first embodiment of the present invention has been described. According to the present invention, each part of the second radiation pattern 30, more specifically, the 2-1st radiation pattern 30-1 and the 2-2nd radiation pattern 30-2 is the first radiation pattern 10 By being disposed in the first gap G1 and the second gap G2 including this, it can be disposed together on one side and the other side of the base film 10 without overlapping with the first radiation pattern 20, one By effectively implementing each of the wireless charging function and the non-contact short-range communication function through the antenna module, an overwhelming advantage can be obtained in terms of securing space for component installation. In addition, the second radiation pattern 30 enters the blank area E formed in the inner direction of the first radiation pattern 20 on one surface of the base film 10, and the first radiation pattern on the other surface of the base film 20. As it advances to the outside of (20), the area of the base film 10 and furthermore the size of the entire antenna module can be drastically reduced by improving the usefulness of the radiation pattern design area on each side of the base film 20. .

Hereinafter, a magnet according to a second embodiment of the present invention capable of providing competitiveness differentiated from other competitors by dramatically improving wireless charging efficiency based on the magnet type combo antenna module 100 according to the first embodiment of the present invention. The type combo antenna module 1000 will be described.

5 is a top view of a magnet type combo antenna module 1000 according to a second embodiment of the present invention.

The magnet type combo antenna module 1000 according to the second embodiment of the present invention includes the base film 10 included in the magnet type combo antenna module 100 according to the first embodiment of the present invention, and the first radiation pattern 20 ) and the second radiation pattern 30 and detailed configurations therefor as they are, and further includes a magnet line 40 additionally. Hereinafter, the magnet line 40, which is different from the magnet type combo antenna module 100 according to the first embodiment of the present invention, will be described in order to prevent redundant description.

The magnet lines 40 are disposed on one surface of the base film 10 and are spaced apart from each other by a predetermined distance in an outward direction of a part of the first radiation pattern 20 .

Here, the magnet line 40 literally means a line-type configuration made of magnets, and may include one or more magnets, where the magnets may be monopole magnets or multipole magnets.

More specifically, when the magnet line 40 is configured with a single-pole magnet, as exemplarily shown in FIG. 6, the magnet line 40 includes at least one N-pole magnet and at least one S-pole magnet to include the N-pole. It can be configured so that the magnet and the S-pole magnet are alternately arranged, and when the magnet line 40 is configured with a multi-pole magnet, as exemplarily shown in FIG. 7, one magnet shows both the N-pole and the S-pole. Because of this, it can be configured so that a plurality of magnets are arranged in succession.

Meanwhile, referring to FIG. 5 , the magnet line 40 is disposed spaced apart in a predetermined direction from the outermost direction of the first radiation pattern 20, more specifically, the outermost radiation pattern of the 1-1st radiation pattern 20-1. , and an area extending beyond the width of the first gap G1 at the 2 o'clock direction where the first gap G1 is disposed can be confirmed. The corresponding area is the first gap T1.

The first gap T1 is a part of the 2-1 radiation pattern 30-1 disposed in the first gap G1, more specifically, a part of the 2-1 radiation pattern 30-1 and extending therefrom. Since the remaining part is an area to be connected to the terminal by being disposed inside, since the 2-1 radiation pattern 30-1 is an NFC pattern, when it directly contacts the magnet line 40 made of magnets, performance due to the influence of magnetic force Since degradation occurs, this is prevented through the first gap T1, and the 2-1st radiation pattern 30-1 disposed inside the first gap T1 is preferably 1 mm or more from the first gap T1. It is preferable to arrange them sufficiently spaced apart.

Meanwhile, the magnet line 40 may further include a second gap T2 formed in a direction in which the second gap G2 is disposed, the width of the second gap G2 or greater, which is the base film 10 This is because the second-second radiation pattern 30-2, which is an NFC pattern, is disposed on the other surface of ). More specifically, while the magnet line 40 is disposed on one surface of the base film 10, the 2-2 radiation pattern 30-2 is disposed inside the second gap G2 disposed on the other surface of the base film 10. Although the planes on which both components are arranged are different by being disposed on, the effect of the magnetic force of the magnet line 40 on the 2-2nd radiation pattern 30-2 only by the fact that the very thin base film 10 is present therebetween. Since it is impossible to remove all of them, this is prevented by forming a second gap T2, and accordingly, a part of the 2-2 radiation pattern 30-2 is formed on the other surface of the base film 10 by forming a second gap (T2). T2), it can be seen that the remaining part of the 2-2 radiation pattern 30-2 is part of the area corresponding to the magnet line 40 on the other surface of the base film 10 It can be seen that it is arranged to be included inside.

8 reflects this, in the magnet type combo antenna module 1000 according to the second embodiment of the present invention, the 2-1st radiation pattern 30-1, which is an NFC pattern, is inside the first gap T1, When the 2-2nd radiation pattern 30-2 is disposed inside the second gap T2 (the present invention) and otherwise the second radiation pattern 30 is directly contacted by being disposed on the magnet line 40 This is a table showing the types of cards that approximate cases (Ref), and the numbers in parentheses of each card type indicate the minimum distance required to recognize the corresponding card type.

8, in the case of Ref, Topaz type card, Ultralight type card, Ultralight-C type card, Mifare EV1 type card, Tec tile type card, Type B 16M type card, Octopus type card, ISO 15693 type card, Mifare Classic 1K While the recognizable distances for type cards are sequentially 24mm, 32mm, 7mm, 7mm, 5mm, 8mm, 18mm, 20mm, and 28mm, according to the present invention, the recognizable distances are sequentially 46mm, 60mm, 27mm, 26mm, and 24mm. , 26mm, 38mm, 62mm, 68mm, it can be seen that the recognition distance is about 2 to 4 times more for all types of cards, so by placing the NFC pattern inside the gap, the performance related to non-contact short-range communication is dramatically improved. can be seen as

Additionally, when the second radiation pattern 30 itself operates as a card, similarly, it shows a recognizable distance that is about 2 to 3 times greater than Ref, so it can be seen that performance related to non-contact short-range communication has improved dramatically.

Meanwhile, in the above-described first gap T1 and second gap T2, the second radiation pattern 30 enters the empty area E formed in the inner direction of the first radiation pattern 20 once. Then, it is applied to the embodiment for the case of entering once, and it will be said that in the case of entering or exiting multiple times, a corresponding number of gaps may be additionally formed. For example, in the case of entering twice and exiting twice, four gaps may be formed in consideration of the characteristic of not being able to exit through the same path as the entered path.

FIG. 9 shows wireless charging efficiency when the magnet line 40 is not included (Ref) and when the magnet line 40 is included (the present invention) in the magnet type combo antenna module 1000 according to the second embodiment of the present invention. it is one table

Referring to FIG. 9, in the case of Ref, since both the antenna module and the wireless charger do not include the magnet line 40, the charging efficiency is 75.22%, and in the case of the present invention, both the antenna module and the wireless charger include the magnet line 40. It can be seen that the efficiency is 76.01%, and the difference in time required for full charge in the discharge state according to the difference in efficiency is about 5 minutes, which can be significantly shortened in the case of the present invention. Since the charging efficiency of 75.22% does not include the magnet line 40, wireless charging must be attempted while matching the center of the antenna module included in the mobile communication device (not shown) with the center of the wireless charger. In contrast to efficiency, when actual users place a mobile communication device (not shown) on a wireless charger for wireless charging, in most cases wireless charging proceeds in a state where the center is not aligned. In this case, 75.22% charging Efficiency may further drop within a range of up to about 10%, and accordingly, a difference in time required for full charge in a discharged state may be more remarkably widened.

So far, the magnet type combo antenna module 1000 according to the second embodiment of the present invention has been described. According to the present invention, by disposing the magnet line 40 in the outer direction of a part of the 1-1 radiation pattern 20-1 disposed on one surface of the base film 10, the wireless charging efficiency related to the wireless charging function is improved. It can be improved dramatically, which can have the effect of significantly shortening the time required for wireless charging. In addition, the magnet line 40 includes a first gap T1 and a second gap T2, and the 2-1 radiation pattern 30-1 is formed in the first gap T1, and the second gap T2 Since the 2-2 radiation pattern 30-2 is disposed on the other side of the base film 10 corresponding to , the non-contact short-range communication function is also dramatically improved.
