An NFC extension antenna loop 346 may be formed on the same surface of the substrate 200 on which the NFC antenna chip 246 is mounted, that is, on the upper surface 200a of the substrate 200. [ One end of the NFC extension antenna loop 346 is connected to at least one of the NFC antenna chip 246 and the NFC matching device 245 by using the via pattern 500 and the first conductive line pattern 346a passing through the substrate 200, And the NFC connection terminal 430, as shown in FIG. Referring to FIG. 1C, an NFC antenna chip 246 may be disposed at the lower end of the upper surface 200a of the substrate 200. FIG. One end of the NFC antenna chip 246 may be electrically connected to at least one NFC matching element 245. And one end of the NFC matching element 245 and the NFC extension antenna loop 346 can be electrically connected. The NFC extension antenna loop 346 may be formed by bending at least once around the outermost portion of the upper surface 200a of the substrate 200. [ The NFC antenna chip 246, the NFC matching element 245, the NFC extension antenna loop 346 and the NFC connection terminal 430 are similar to the configuration in which the wireless charging antenna chip 248 is connected to the wireless charging connection terminal 342 And may be electrically connected to each other by at least two via patterns 500.

Although not shown, the wireless charging extension antenna loop 348 and the NFC extension antenna loop 346 are opposed to one surface of the substrate 200 on which the wireless charging antenna chip 248 and the NFC antenna chip 246 are mounted As shown in Fig.

Alternatively, the wireless charge extension antenna loop 348 and / or the NFC extension antenna loop 346 may be patterned in a loop pattern formed on the top surface 200a and / or the bottom surface 200b of the substrate 200, That is, a conductive line pattern. The wireless charge extension antenna loop 348 and / or the NFC extension antenna loop 346 may be a pattern formed by bending in at least one spiral form.

That is, a plurality of lines are formed by rotating counterclockwise about a central axis perpendicular to the substrate 200, and the wireless filler extension antenna loop 348 is formed by using the via pattern 500 provided on the substrate 200 . The NFC extension antenna loop 346 forms a loop surrounding the outermost periphery of the wireless fill extension antenna loop 348 and forms a loop through the via pattern 500 formed in a region different from the via pattern 500 to which the wireless fill extension antenna loop 348 is connected ) Can be used to electrically connect to other parts. Here, the loop has an arbitrary shape capable of generating an inductance. Also, the loop is not necessarily limited to a closed loop.

On the other hand, the length of the NFC extended antenna loop 346 is set such that the ratio of the inductance value generated in the NFC extended antenna loop 346 to the inductance value generated in the NFC antenna chip 246 shown in FIG. 3 is 13% .

The conductive line pattern shown in FIG. 1A, that is, the NFC extended antenna loop 346, has a shape that can generate an inductance, and may have at least some shape of a loop that can generate, for example, an inductance. The inductance is a quantity representing the ratio of the counter electromotive force generated by the electromagnetic induction by the change of the current flowing through the circuit, and the unit is H (Henry).

The present inventor has found that the inductance value generated in the NFC extended antenna loop 346 is larger than the inductance generated in the NFC antenna chip 246 because the NFC extended antenna loop 346 does not remain in a simple conductive pattern but substantially serves as an auxiliary antenna. Value should be more than a predetermined ratio.

Table 1 shows the results of testing whether the NFC auxiliary antenna functions according to the magnitude of the inductance value generated in the NFC extended antenna loop 346 when the inductance value generated from the NFC antenna chip 246 is 0.56 μH.

Experimental Example Extended antenna inductance value (μH) Extension antenna length (mm) Inductance ratio NFC auxiliary antenna
Functionality Experimental Example 1 0.04 34 6% x Experimental Example 2 0.05 37 8% x Experimental Example 3 0.07 43 11% x Experimental Example 4 0.08 47 13% o Experimental Example 5 0.09 50 14% o

Referring to Experimental Example 1, when the length of the NFC extended antenna loop 346 forming the loop is 34 mm, the inductance value generated in the NFC extended antenna loop 346 is 0.04 μH, but the NFC extended antenna loop 346 is NFC The auxiliary antenna function can not be performed. That is, when the inductance value generated in the NFC extended antenna loop 346 is only 6% of the inductance value generated in the NFC antenna chip 246, the extended antenna configured with the NFC extended antenna loop 346 is introduced. However, Of the population.

On the other hand, referring to Experimental Example 4, when the length of the NFC extended antenna loop 346 forming the loop is 47 mm, the inductance value generated in the NFC extended antenna loop 346 was 0.08 μH and the NFC extended antenna loop 346 ) Performed the NFC auxiliary antenna function. That is, when the inductance value generated in the NFC extended antenna loop 346 reaches 13% of the inductance value generated in the NFC antenna chip 246, the NFC extended antenna loop 346 outputs the NFC- .

In other words, the length of the NFC extended antenna loop 346 constituting the extended antenna is set to be equal to or longer than the predetermined length, and the value of the inductance generated in the NFC extended antenna loop 346 and the value of the inductance It has been confirmed that the NFC recognition distance is improved by the extension antenna constituted by the NFC extension antenna loop 346 when the ratio of the value of the inductance generated in the chip 246 is equal to or larger than a predetermined ratio (for example, 13%).

As described above with reference to Table 1, since the length of the extended antenna is secured to be equal to or longer than the predetermined length, the value of the inductance generated in the NFC extended antenna loop 346 and the value of the inductance generated in the NFC antenna chip 246 When the ratio of the inductance value is not less than a predetermined ratio (for example, 13%), it is confirmed that the NFC recognition distance is improved by the extension antenna.

In addition, for example, a frequency region for NFC communication of 13.56 MHz can be generated using the resonance occurring in the capacitor, which is the NFC antenna chip 246 and the NFC matching device 245, to communicate with the NFC device.

Meanwhile, the NFC antenna chip 246 corresponds to an inductor. Here, although not shown, an NFC control integrated circuit portion and a second capacitor portion may be embedded in the antenna module package 1000a. Also, the antenna module package 1000a may be built in the centrifugal chip to be one-chip.

In addition, the NFC antenna chip 246 may support Near Field Communication (NFC), for example. It includes an inductor that can resonate in the NFC frequency band, and can have a variety of winding configurations. For example, it may have a chip shape as shown in Figs. 1 (a) and 1 (b). The NFC antenna chip 246 may include an inductor capable of resonating in the NFC frequency band, wherein the inductor making up the NFC antenna chip 246 corresponds to at least a portion of the first inductor.

Furthermore, the NFC antenna chip 246 according to the embodiment of the present invention may further include at least one selected from a first capacitor unit, a second capacitor unit, and an NFC control integrated circuit unit.

In the case of the NFC antenna according to the comparative example of the present invention, the film-shaped NFC antennas are disposed and soldered through the soldering process in the process of assembling the battery pack. However, the NFC antenna chip 246 according to the embodiment of the present invention The antenna soldering process can be omitted, and the NFC antenna chip 246 can be mounted and sealed in the form of a chip to enhance the shear strength from the viewpoint of the overall structure.

Referring to FIGS. 1 (a) and 1 (b), an NFC antenna chip 246 including an inductor capable of resonating in an NFC frequency band may have various winding structures.

As a first example, the winding structure shown in Fig. 1 (c) includes a coil having a first winding direction. For example, the winding structure may include a core 246a of nickel ferrite; And a coil 246c having a first winding direction wound in a direction parallel to the x-axis direction and the z-axis direction so as to surround the bobbin 246b. In this case, near field communication can be realized when the direction of the induced magnetic field generated in conjunction with the NFC reader is positioned in parallel with the y axis direction.

As a second example, the NFC antenna chips 246 including the winding structure shown in FIG. 1 (b) can be arranged in a plurality of spaced apart from each other. If the NFC antenna has a chip shape, a plurality of chips including the NFC antenna may be provided. The description of each winding structure is the same as that described in the first example. That is, each of the plurality of NFC antenna chips 246 may include a coil 246c having the same first winding direction as shown in FIG. 1C (a). On the other hand, as a modified embodiment, when the NFC antenna has a chip form, a plurality of chips including the NFC antenna may be provided in the single chip, and a plurality of the coil structures shown in FIG. have. In the case of having such a winding structure, the effect of improving the sensitivity of the short-range magnetic field communication can be expected as compared with the case of the NFC antenna chip 246 of the first example.

As a third example, the NFC antenna chip 246 includes a plurality of NFC antenna chips 246 spaced from each other, and some NFC antenna chips 246 of the plurality of NFC antenna chips 246 are arranged as shown in FIG. 1C (a) And a coil 246c having a first winding direction, and the remaining NFC antenna chip 246 of the plurality of NFC antenna chips 246 includes a first coil winding 246a, as shown in FIG. 1C (b) And a coil 246c having a second winding direction perpendicular to the winding direction. For example, the winding structure having the first winding direction may include a core 246a made of nickel ferrite; And a coil (246c) wound in parallel with the x-axis direction and the z-axis direction so as to surround the bobbin (246b), and the winding structure having the second winding direction includes a core (246a) made of nickel ferrite; And a coil 246c wound in a direction parallel to the y-axis direction and the z-axis direction so as to surround the bobbin 246b.

If the NFC antenna has a chip form, the first antenna structure having a chip-shaped winding structure having the first winding direction and the second antenna structure having a chip-shaped winding structure having the second winding direction . As another example, a winding structure including a coil 246c having the first winding direction and a coil 246c having the second winding direction in a single chip including an NFC antenna chip 246 Respectively. In the case of having such a winding structure, near field communication can be realized even if an arbitrary angle is formed without being positioned side by side, and the sensitivity of the near field communication can be expected to be improved.

On the other hand, the winding wire structure constituting the NFC antenna chip 246 has been described as a winding structure in which a coil is wound around the core as an example. However, the NFC antenna chip 246 according to the technical idea of the present invention is not limited to this winding structure, and may be realized by patterning a conductive material, for example.

On the other hand, the wireless charge extension antenna loop 348 shown in FIG. 1C can be implemented as a conductive line pattern in the form of a loop. When both ends of the wireless charging extension antenna loop 348 are in contact with the wireless charging connection terminal 432, they can be electrically connected to the capacitor, which is the wireless charging matching device 247, to form a closed loop. For example, a resonance generated in a capacitor, which is a wireless charging antenna chip 248 and a wireless charging matching device 247, can be used to generate a 125 kHz wireless charging communication frequency region and communicate with the wireless charging device. The wireless charging antenna chip 248 may have a chip shape, for example, as illustrated in FIGS. 1C and 2D.

As described above, when a conventional NFC antenna and a wireless charging antenna are used, the mounting position is very limited due to the size of the antenna by using the RF antenna. Further, if a battery pack is manufactured by employing a metal body, the performance of the antenna is reduced. In addition, when the NFC chip antenna or the wirelessly-recharged chip antenna is used, the antenna size is small, and the recognition range distance is limited according to the size of the NFC chip antenna and the wireless recharging chip antenna.

In order to solve this problem, the antenna module package according to the embodiment of the present invention can be integrated and miniaturized, and it is possible to give a degree of freedom to the positioning of the antenna. Further, an antenna array using a plurality of wireless charging antenna chips or an antenna array using a plurality of wireless charging antenna chips and an extended antenna loop are combined to broaden the recognition range and distance of the antenna, thereby providing an antenna module package with improved antenna performance can do. In addition, it is formed directly on the main set separately from the battery protection circuit package, and can perform the NFC antenna and the wireless charging function.
