A matching circuit or the like that makes it suitable for proximity wireless communication may be disposed.

According to various embodiments, the MST module 157c may generate magnetic flux through the conductive pattern part 105 . For example, the MST module 157c generates a magnetic flux through at least one of the first, second, and/or third conductive patterns 153a, 153b, and 153c, so that an external device (eg, a POS terminal of a magnetic readout method) ) to transmit information (e.g. payment information). For example, an electronic device (eg, the electronic device 100101 of FIG. 1 ) may periodically transmit an MST signal including payment information several times through an MST module. For example, the MST signal may include payment information included in at least a part of the card.

According to various embodiments, the MST module 157c may be connected to the first, second, and/or third conductive patterns 153a, 153b, and 153c through a switch member (not shown), respectively. The first, second, and/or third conductive patterns 153a, 153b, and 153c are formed on a line connecting the switch member and the first, second, and/or third conductive patterns 153a, 153b, and 153c, respectively.

FIG. 11 is a block diagram illustrating a configuration for transmitting payment information in an electronic device 100 (eg, the electronic device 101 of FIG. 1) according to one of various embodiments of the present disclosure.

In various embodiments of the present invention, configurations for generating magnetic flux using the aforementioned third conductive pattern 153c will be described. However, this disclosure does not limit the present invention, and the configuration and operation of the third conductive pattern 153c disclosed in various embodiments below may be performed through the first and/or second conductive patterns 153a and 153b described above. can be implemented

Referring to FIG. 11 , a conductive pattern (eg, the third conductive pattern 153c) according to various embodiments may be formed of a plurality of turns in which one conductive line is wound or extended in a polygonal shape, and different It may include first and second sections 153d and 153e each including a conductive line of the specification.

12 is a plan view illustrating an example of a conductive pattern for transmitting payment information in an electronic device (eg, the electronic device 101 of FIG. 1 ) according to one of various embodiments of the present disclosure.

Referring to FIG. 12, among the regions where the conductive lines constituting the conductive pattern 153c are disposed, the conductive line portions disposed in the first section 153d are larger than the conductive line portions disposed in the second section 153e. can have a width. For example, in FIG. 12 , the third conductive pattern 153c may be formed of a planar coil having an asymmetric top and bottom shape.

According to one embodiment, the conductive pattern may be a loop antenna. The conductive pattern may be designed so that the strength of the magnetic field is different for each region. A location of a shadow area (eg, the aforementioned null section) of a conductive pattern occurring in the terminal may be moved. For example, the width of the antenna pattern (eg, the conductive line) of the first section 153d may be wider than that of the antenna patterns arranged in the second section 153e. Accordingly, when current flows, the resistance of the region of the first section 153d is relatively lower than that of the second section 153e, and thus, the strength of the magnetic field generated in the first section 153d is reduced in the second section. It may be stronger than the strength of the generated magnetic field. When the strength of the magnetic field generated in the first section 153d is stronger than the strength of the magnetic field generated in the second section 153e, the shadow area of the loop antenna may be formed at the lower end of the terminal instead of the center. For example, as shown in FIGS. 28 to 31 , while payment is in progress, the electronic device (eg, the electronic device 101 of FIG. 1 ) determines the MST recognition range (eg, 'the area between the center and the upper end of the terminal'). ), and the user makes the MST recognition range closer to the reader, thereby improving the MST recognition rate. According to an embodiment, even if the pattern thickness of the first section 153d area is the same, separate conductive patterns may be formed at the bottom of the first section 153d area, and the strength of magnetic flux generated accordingly can be implemented more robustly.

FIG. 13 is a graph showing examples of measured values by measuring magnetic flux generated by the conductive pattern shown in FIG. 12 .

Referring to FIG. 13 , it can be seen that the magnetic flux generated by the third conductive pattern 153c shown in FIG. 12 may have an asymmetrical shape. For example, the magnetic flux generated in the first section 153d may be greater than the magnetic flux generated in the second section 153e. As the magnetic flux radiated from the first section 153d on the third conductive pattern 153c increases, a null section is formed from the center of the third conductive pattern 153c to the second section 153e. ) may be biased in the direction in which it is located.

According to various embodiments, it has been previously described that a null section is generated at the center and a symmetrical magnetic flux is generated in a planar coil having a top, bottom, left, and right symmetry. 12 (e.g., the third conductive pattern 153c) when the conductive line arrangement area and number of turns are manufactured to be the same as those of a planar coil having a symmetrical shape and the same signal current is applied. )) may generate a magnetic flux in which the null section moves from the central portion to close to one edge. Alternatively, it can be seen that the planar coil shown in FIG. 12 radiates magnetic flux from the first section to a wider area than the symmetrical planar coil. Therefore, compared to a symmetrical planar coil, information (eg, payment information) is easily transmitted to an external device (eg, a POS terminal of a magnetic reading method) through the magnetic flux generated by the third conductive pattern 153c. It can be.

14 to 18 are plan views illustrating various examples of conductive patterns for transmitting payment information in the electronic device 100 according to one of various embodiments of the present disclosure.

Referring to FIG. 14, in disposing one conductive line constituting the third conductive pattern 153c, even though portions of the conductive line having the same number of turns are disposed in the first and second sections 153d and 153e, respectively, the first and second sections 153d and 153e have the same number of turns. The conductive line portions disposed in one section 153d may be distributed over a wider area. By forming the first section 153d in a wider area than the second section 153e, the null section extends from the center of the third conductive pattern 153c to one side (eg, the lower side in FIG. 14). While moving, a larger amount of magnetic flux may be radiated from the first section 153d.

Referring to FIG. 15 , in disposing one conductive line constituting the third conductive pattern 153c, a plurality of turns wound in a coil form may be disposed in each of the first and second sections 153d and 153e. . A plurality of turns wound in a coil shape on each of the first and second sections 153d and 153e may generate current flow in the same direction (eg, counterclockwise direction). Current generated in the first and second sections 153d and 153e may flow in a clockwise direction according to the signal current applied to the conductive line constituting the third conductive pattern 153c.

According to various embodiments, the coil disposed in the first section 153d may be disposed to occupy a wider area than the coil disposed in the second section 153e and may have more turns. For example, the conductive line may be wound 5 times in the first section 153d and may be wound 3 times in the second section 153e. By making the number of turns of the coils disposed in each section and the area in which the coils are disposed different, the null section moves from the center of the third conductive pattern 153c to one side (e.g., the upper side in FIG. 15), A greater amount of magnetic flux may be radiated from the first section 153d. Also, according to an embodiment, even if the number of coil turns disposed in the first section 153d and the number of coil turns disposed in the second section 153e are the same, the null section of the third conductive pattern 153c It may be formed on one side from the central portion (eg, a side between the null section of FIG. 12 and the central portion of the third conductive pattern). According to one embodiment, the null intervals formed according to the shape of FIG. 15 may be more dispersed than when the areas occupied by each session are the same. That is, as described above, the formation position of the null section and the width of the section where the magnetic flux is radiated may be formed differently according to the arrangement of the conductive patterns.

Referring to FIG. 16 , in disposing one conductive line constituting the third conductive pattern 153c, a plurality of turns wound in a coil form may be disposed in each of the first and second sections 153d and 153e. . A plurality of turns wound in a coil form on each of the first and second sections 153d and 153e may generate current flow in opposite directions (eg, counterclockwise direction) with respect to each other. For example, if the current generated in the first section 153d flows in a counterclockwise direction, the current generated in the second section 153e may flow in a clockwise direction.

The coils formed by the conductive lines in each of the first and second sections 153d and 153e may be formed in the same area while varying the number of turns (eg, the number of turns). For example, a coil disposed in the first section 153d may have a larger number of turns, and a magnetic flux radiated from the first section 153d is greater than a magnetic flux radiated from the second section 153e. There can be many. Therefore, the null section of the magnetic flux radiated by the third conductive pattern 153c may move from the center of the third conductive pattern 153c to one side (eg, the upper side in FIG. 16 ), and the first section More magnetic flux can be radiated at (153d). Further, according to one embodiment, when the number of turns of the coils disposed in the first section 153d and the number of turns of the coils disposed in the second section 153e are the same, the magnetic flux by the coils disposed in the plurality of sections is 3 can be more concentrated on the central portion (C) of the conductive pattern, so the recognition rate of the MST module can be increased. That is, as described above, the formation position of the null section and the width of the section where the magnetic flux is radiated may be formed differently according to the arrangement of the conductive patterns.

Referring to FIGS. 17 and 18, the third conductive pattern 153c has a coil shape, for example, a first section 153d is disposed in the center, and a second section 153d is disposed around the circumference of the first section 153d. Section 153e may be disposed. The first section 153d is formed to occupy a smaller area than the second section 153e, but may include a larger number of conductive line parts. For example, the first section 153d includes a larger number of conductive line parts in a small area or space, such as a solenoid type coil, so that a larger number of conductive line parts are included than a flat type coil (eg, a coil formed by conductive lines in the second section). A positive magnetic flux can be radiated. For example, the magnetic flux emitted from the second section 153e may be left-right symmetric about the central portion, and a null section may be formed in the central portion. The first section 153d is disposed at the center of the second section 153e to radiate a strong magnetic flux, thereby compensating for a null section of the magnetic flux formed by the second section 153e. For example, the third conductive pattern 153c shown in FIGS. 17 and/or 18 may generate a greater magnetic flux from the edge to the center.

Through the above-described various embodiments, the shapes of the conductive pattern (eg, the above-described third conductive pattern 153c), the conductive pattern of the above-described embodiment includes the above-described first and/or second conductive patterns 153a and 153b. can be used to form. According to another embodiment, the present invention need not be limited to the conductive patterns of the various embodiments described above, and the magnetic field and/or magnetic flux can be changed according to the direction in which the null section is to be moved and/or by moving the null section. Depending on the area to be formed stronger, the conductive pattern can be formed in various ways.

As described above, the conductive pattern (eg, the aforementioned third conductive pattern 153c) according to various embodiments of the present disclosure may provide a plurality of current flow paths. For example, it may have first and second current flow paths, and the direction of the current flowing through each of the first and second paths may be designed to be the same. According to various embodiments, the conductive pattern according to various embodiments of the present disclosure may further provide a third flow path, and the direction and intensity of current flowing through the first, second, and/or third paths, respectively. , Move the null section closer to one side of the conductive pattern (eg, to the lower part of the conductive pattern) according to the arrangement of the conductive lines forming each path, and move the null section closer to the other side (eg, to the top and/or center of the conductive pattern) It can generate a magnetic field and/or magnetic flux.

It may be applied to the second coils 153f and 153g. The first and second coils 153f and 153g may be disposed adjacent to each other.

If the conductive pattern 153c according to various embodiments is formed on a multilayer circuit board, for example, a flexible printed circuit board, the first and second coils 153f and 153g may be formed on the same layer of the flexible printed circuit board.

When the same signal is simultaneously applied to the first and second coils 153f and 153g, the first and second coils 153f and 153g flow current in the same direction, for example, clockwise. can create In the third conductive pattern 153c composed of the first and second coils 153f and 153g, the null section is biased to one side or the other side according to the magnetic flux generated by the first and second coils 153f and 153g, respectively.

When the same signal is applied to the first and second coils 153f and 153g at the same time, the first and second coils 153f and 153g may respectively generate current flows in opposite directions with respect to each other. For example, if the first coil 153f generates a current flow in a clockwise direction, the second coil 153g may generate a current flow in a counterclockwise direction. In the third conductive pattern 153c composed of the first and second coils 153f and 153g, the null section is biased to one side or the other side according to the magnetic flux generated by the first and second coils 153f and 153g, respectively. A magnetic flux can be created.

When the same signal is applied to the first and second coils 153f and 153g at the same time, the second coil 153g having more turns and occupying a larger area becomes the first coil 153f. A larger amount of magnetic flux can be radiated. For example, when the same signal is applied to each of the first and second coils 153f and 153g disposed as shown in FIG. 22 , the null section generated by the third conductive pattern 153c may be biased from the center to the left.

According to various embodiments, the first and second coils 153f and 153g forming the third conductive pattern 153c may have a planar coil shape disposed on the same plane, but may have a solenoid coil shape. there is.

If the above-described first and second coils 153f and 153g are formed of planar coils, they may include any one of the third conductive patterns 153c shown in FIGS. 12 to 18 .

The preset selection condition may include a case of selection based on a distance between an external device to receive payment information and an electronic device. For example, the MST module 157c may transmit payment information through a coil selected from among the first coil and the second coil, and based on whether a response to the payment information is received or the contents of the response, the first coil or the second coil may be transmitted. Payment information may be transmitted again through another unselected coil.
