Here, although not shown, the NFC extension antenna loop 346 and the wireless charge extension antenna loop 348 may be formed on the other surface opposite to one surface of the substrate 200 on which the antenna chip 140 is mounted.

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.

The length of the NFC extended antenna loop 346 is set such that the ratio of the value of the inductance generated in the NFC extended antenna loop 346 to the value of the inductance generated in the antenna chip 140 shown in FIG. Can be set.

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 value generated in the antenna chip 140 because the NFC extended antenna loop 346 does not remain in a simple conductive pattern but substantially serves as an auxiliary antenna. It should be more than a predetermined ratio.

Table 1 shows test results of the NFC auxiliary antenna according to the magnitude of the inductance value generated in the NFC extended antenna loop 346 when the inductance value generated from the antenna chip 140 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 antenna chip 140, the extended antenna configured with the NFC extended antenna loop 346 is introduced. However, No improvement was seen.

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 antenna chip 140, the NFC extended antenna loop 346 outputs an NFC- Improvement appeared.

The results of Experimental Examples 1 to 5 indicate that the length of the NFC extended antenna loop 346 constituting the extended antenna is kept longer than the predetermined length so that the value of the inductance generated in the NFC extended antenna loop 346, It is confirmed that the NFC recognition distance is improved by the extension antenna formed by the NFC extension antenna loop 346 when the ratio of the inductance value generated in the antenna 140 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 inductance generated in the antenna chip 140 (For example, 13%), the improvement of the NFC recognition distance is confirmed by the extended antenna.

In addition, for example, a frequency region for NFC communication of 13.56 MHz can be generated using the resonance generated in the capacitor, which is the antenna chip 140 and the NFC matching device 245, to communicate with the NFC device.

Meanwhile, the antenna chip 140 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 1000.

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 antenna chip 140 may include an inductor capable of resonating in the NFC frequency band.

Furthermore, the antenna chip 140 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 in the process of assembling the battery pack, and are bonded through the soldering process. However, in the antenna chip 140 according to the embodiment of the present invention, The antenna soldering process can be omitted, and the antenna chip 140 can be mounted and sealed in a chip form, thereby improving the shear strength from the viewpoint of the overall structure.

Referring to FIGS. 1 (a) and 1 (b), an antenna chip 140 including an inductor capable of resonating in a predetermined frequency band may have various winding structures. For example, when the predetermined frequency band is the NFC frequency band, the following will be described.

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 140a of nickel ferrite; And a coil 140c 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 140b. 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 antenna chips 140 including the winding structure shown in FIG. 1 (b) may 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 antenna chips 140 may include a coil 140c 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 antenna chip 140 of the first example.

As a third example, the antenna chip 140 includes a plurality of antenna chips 140 spaced from each other, and a part of the antenna chips 140 of the plurality of antenna chips 140 are connected to the first And a coil 140c having a winding direction and the remaining antenna chip 140 of the plurality of antenna chips 140 is formed so as to be perpendicular to the first winding direction as shown in FIG. And a coil 140c having a second winding direction. For example, the winding structure having the first winding direction may include a core 140a made of nickel ferrite; And a coil 140c wound in parallel with the x-axis direction and the z-axis direction so as to surround the bobbin 140b. The winding structure having the second winding direction includes a core 140a 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 140b.

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 winding structure including the coil 140c having the first winding direction and a coil 140c having the second winding direction in a single chip including the antenna chip 140 . 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, a winding wire structure constituting the antenna chip 140 has been described as a winding structure in which a coil is wound around a core as an example. However, the antenna chip 140 according to the technical idea of the present invention is not limited to such a winding structure, and may be realized by, for example, patterning a conductive material.

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, by using the resonance generated in the capacitor, which is the antenna chip 140 and the wireless charging matching device 247, a frequency region for 125 kHz wireless charging communication can be created to communicate with the wireless charging device.

For example, a frequency band for wireless card settlement of about 250 kHz can be generated using the resonance generated in the capacitor, which is the antenna chip 140 and the wireless card settlement matching device 249, to communicate with the mobile payment system . Here, the frequency band of about 250 kHz may be changed depending on whether the use of the wireless transmission / reception frequency band in the country or abroad is permitted.

3 is a schematic diagram illustrating an antenna module package circuit according to an embodiment of the present invention.

3, an antenna module package circuit 2100 according to an embodiment of the present invention includes a first inductor L1 and a first capacitor C1 electrically connected to each other and performs a function of a wireless card payment antenna And a second path that can be used for the second path. The first inductor L1, the second inductor L2, and the second capacitor C2, which share the first inductor L1 and are electrically connected to each other. The second inductor L1, the second inductor L2, Path < / RTI > A first inductor L1, a second inductor L2, a third inductor L3, and a third capacitor C3, which share the first inductor L1 and are electrically connected to each other, And a third path that can perform the second path.

In addition, the first inductor L1 may perform at least one of the wireless card payment antenna function, the NFC antenna function, and the wireless charging antenna function, or may perform the antenna functions at the same time. The first capacitor C1, the second capacitor C2, and the third capacitor C3 may each include at least one capacitor.

Specifically, both ends of the first path capable of performing the wireless card payment antenna function are formed of wireless card payment connection terminals (M +, M-) which can be connected to an external connection terminal or a main set of the battery protection circuit package. The inductance can be ensured so that the wireless card payment connection terminals M + and M- and the first inductor L1 and the first capacitor C1 are electrically connected to each other to perform the self-secured connection function.

In addition, both ends of the second path capable of performing the NFC antenna function are composed of NFC connection terminals (N +, N-) which can be connected to the external connection terminal or main set of the battery protection circuit package. The inductance can be ensured to perform the NFC antenna function by electrically connecting the NFC connection terminals N +, N-, the first inductor L1, the second inductor L2 and the second capacitor C2 .

Finally, both ends of the third path capable of performing the wireless charging antenna function are comprised of wireless connection terminals (W +, W-) that can be connected to the external connection terminal or main set of the battery protection circuit package. The wireless charging connection terminal W +, W-, the first inductor L1, the second inductor L2, the third inductor L3 and the third capacitor C3 are electrically connected to perform a wireless charging antenna function The inductance can be secured.

Meanwhile, an inductor can be understood as an element that stores or emits magnetic energy, and a capacitor can be understood as an element that stores or emits electric energy. In the antenna module package circuit 2100, the inductor and the capacitor have opposing values depending on what connection structure (serial connection or parallel connection) is designed.

The inductor and the capacitor have opposite frequency characteristics. If the inductor and the capacitor are connected in series, the impedances of the inductor and the capacitor are equal to each other in a specific frequency (resonance frequency) band. That is, when the impedance becomes minimum, the applied signal (current) has a maximum value, and resonates in a specific frequency band.

On the other hand, when the inductor and the capacitor are connected in parallel, the signal (current) applied has a minimum value when the impedance becomes the maximum, and the specific frequency band is blocked.

When the antenna module package circuit 2100 compares the magnitude of the inductance value of each inductor in each communication area, the inductance value in the wireless charging frequency band is the largest, the inductance value in the NFC frequency band is the next, and finally, The inductance value in the payment frequency band is the smallest. Therefore, the circuit configuration according to the inductance value of each antenna in each communication area can be expressed by the following equations (1) to (3).

[Equation 1]

(Where L _MST is the inductance value of the inductor corresponding to the wireless card settlement frequency band and L ₁ is the value of the inductance of the first inductor).

&Quot; (2) "

(Where L _NFC is the inductance value of the inductor corresponding to the NFC frequency band, L ₁ is the inductance value of the first inductor, and L ₂ is the inductance value of the second inductor).

&Quot; (3) "

(Wherein, L _WPC is the inductance of the inductor for the wireless charging frequency band, L ₁ is a indeon capacitance value of the first inductor, L ₂ is the inductance of the second inductor, L ₃ is a third inductor Inductance value.)

Accordingly, since a plurality of inductors are connected in series to at least one of the first inductor L1, the second inductor L2, and the third inductor L3, the inductance value of the inductor of each communication region can be increased. Alternatively, a plurality of inductors may be connected in parallel to at least one of the first inductor L1, the second inductor L2, and the third inductor L3, so that the inductance value of the inductor of each communication region may be reduced.

That is, the inductance value in the frequency band of the first path is smaller than the inductance value in the frequency band of the second path, and the inductance value in the frequency band of the second path is smaller than the inductance value in the frequency band of the third path. Therefore, in the case of the NFC antenna, more inductors may be connected in series than the wireless card payment antenna. In the case of a wireless charging antenna, more inductors may be connected in series than in the case of the NFC antenna. Here, the inductor may be formed of various materials such as a printed circuit board (PCB), a flexible printed circuit board (FPCB), or a coil.

4 is a schematic diagram illustrating an antenna module package circuit according to another embodiment of the present invention.

4, an antenna module package circuit 2200 according to another embodiment of the present invention includes a first inductor L1, a second inductor L2, and a first capacitor C1 electrically connected to each other, And a first path capable of performing a wireless card payment antenna function. The first inductor L1, the second inductor L2, the third inductor L3, and the second capacitor C2, which share the first inductor L1 and the second inductor L2 and are electrically connected to each other, And a second path capable of performing an NFC antenna function. In addition, the first inductor L1, the second inductor L2, the third inductor L3, the fourth inductor L4, and the fourth inductor L4, which share the first inductor L1 and the second inductor L2 and are electrically connected to each other, A third capacitor C3, and a third path capable of performing a wireless charging antenna function.

The first inductor L1 and the second inductor L2 may perform at least one of the radio card payment antenna function, the NFC antenna function, and the wireless charging antenna function or may simultaneously perform the antenna functions. The antenna module package circuit 2200 shown in FIG. 4 shares one more inductor than the antenna module package circuit 2100 shown in FIG. 3, so that the antenna module package circuit 2200 can be wider in size, .

3 except that the first inductor L1 and the second inductor L2 are shared, detailed description thereof will be omitted.

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 antenna chip is used, the antenna size is small, so that the recognition range distance is limited according to the size of the antenna chip, thereby reducing the performance of the 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. Also, an antenna array using a plurality of antenna chips or an antenna array using a plurality of antenna chips and an extended antenna loop can be combined to broaden recognition range and distance of the antenna, thereby providing an antenna module package with improved antenna performance.

In addition to the above-described NFC antenna function and wireless charging antenna function, a wireless card settlement (wireless card settlement) antenna function can be added to one chip. Therefore, the area for transmission and reception of the antenna module package can be minimized by sharing the antenna chip with a circuit capable of performing each antenna function. In addition, by providing an inductance value corresponding to a frequency band different from the frequency band, it is possible to perform an antenna function in various frequency regions (multiple frequency bands) through an inductor in addition to the antenna function.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
