Fig. 1 is a diagram presenting a mobile terminal according to an exemplary embodiment, and fig. 2 is a block diagram presenting relationships between a 1 st matching circuit and a 2 nd matching circuit and a switching section in a mobile terminal according to an exemplary embodiment.
Referring to fig. 1 and 2, the mobile terminal 100 may include a main board 102, a conductive edge structure 104, an antenna 106, and an electromagnetic shielding material 108. The mobile terminal 100 may include various forms of mobile communication devices, such as a smart phone, a mobile phone, a tablet computer, a notebook computer, a Personal Digital Assistant (PDA), a Personal Multimedia Player (PMP), an audio player (MP3), a smart camera, an electronic dictionary, a smart watch, and a wearable device.
Various circuits or electronic components for controlling the operation of the mobile terminal 100 may be mounted in the main board 102. As the main Board 102, a PCB (Printed Circuit Board) may be used. The 1 st matching circuit 111, the 2 nd matching circuit 113, and the switch portion 115 may be formed on the main board 102.
The 1 st matching circuit 111 is used to adjust the frequency band of the antenna 106 to the 1 st frequency band. The 1 st matching circuit 111 may include at least one of a line pattern having a fixed electrical length, an inductor, and a capacitor. One side of the 1 st matching circuit 111 may be electrically connected to a 1 st connection board 117 formed on the main board 102. The 1 st connection plate 117 may electrically connect the 1 st matching circuit 111 with the conductive edge structure 104. The other side of the 1 st matching circuit 111 may be electrically connected to the 1 st terminal 115a of the switching section 115.
The 2 nd matching circuit 113 is used to adjust the frequency band of the antenna 106 to another 2 nd frequency band different from the 1 st frequency band. The 2 nd frequency band may be a frequency band higher than the 1 st frequency band. The 2 nd matching circuit 113 includes at least one of a line pattern having a fixed electrical length, an inductor, and a capacitor. One side of the 2 nd matching circuit 113 may be electrically connected to a 2 nd connection board 119 formed on the main board 102. The 2 nd connecting plate 119 may electrically connect the 2 nd matching circuit 113 with the conductive edge formation 104. The other side of the 2 nd matching circuit 113 may be electrically connected to the 2 nd terminal 115b of the switching part 115.
In an exemplary embodiment, the 1 st matching circuit 111 is used to adjust the frequency band of the antenna 106 to the mst (magnetic secure transmission) band, such as the 100KHz band. The 2 nd matching circuit 113 is used to adjust the frequency band of the antenna 106 to an nfc (near Field communication) band (e.g., 13.56MHz band).
One side of the switch portion 115 may be electrically connected to a power supply portion 121 formed at the main board 102. The other side of the switch part 115 may be selectively connected to one of the 1 st and 2 nd matching circuits 111 and 113. That is, according to the input switching control signal, the other side of the switching part 115 may be connected to the 1 st terminal 115a to be electrically connected to the 1 st matching circuit 111, or the other side of the switching part 115 may be connected to the 2 nd terminal 115b to be electrically connected to the 2 nd matching circuit 113.
When the switch section 115 is electrically connected to the 1 st matching circuit 111, the antenna 106 can transmit and receive a signal of the 1 st frequency band through the 1 st matching circuit 111. For example, when the 1 st frequency band is the mst (magnetic Secure transmission) band, the antenna 106 may be used for mst (magnetic Secure transmission) communication. That is, when the mobile terminal 100 approaches a settlement terminal (Point of Sales: PO S), the antenna 106 can transmit settlement information to the settlement terminal through MST communication.
If the switch portion 115 is electrically connected to the 2 nd matching circuit 113, the antenna 106 can transmit and receive a signal of the 2 nd frequency band through the 2 nd matching circuit 113. For example, if the 2 nd band is an nfc (near Field C communication) band, the antenna 106 may be used for nfc (near Field communication) communication. At this time, the antenna 106 can function to perform settlement through NFC communication. That is, when the mobile terminal 100 approaches a settlement terminal (Point of Sales: POS), the antenna 106 can transmit settlement information to the settlement terminal through NF C communication. However, the antenna 106 is not limited to this, and may perform a plurality of functions such as a pairing function between adjacent devices or a tag reader function through NFC communication.
In the exemplary embodiment, the antenna 106 is normally used for NFC communication, that is, the switching section 115 is electrically connected to the 2 nd matching circuit 113, and in the case where the mobile terminal 100 performs the MST settlement function, it is used for MST communication. That is, the switch section 115 is connected to the 1 st matching circuit 111. That is, the switch part 115 may switch from the 2 nd matching circuit 113 to the 1 st matching circuit 115 according to a switch control signal generated when the mobile terminal 100 performs the MST settlement function.
The conductive edge structure 104 may be provided along an edge of a lattice frame (not shown) of the mobile terminal 100. The conductive edge structure 104 serves to beautify the appearance of the mobile terminal 100. The conductive edge structures 104 may be formed from an electrically conductive material such as a metal. At least one of the conductive edge formations 104 may be segmented. That is, the conductive edge formation 104 can include a segment 104 a.
At least one mounting portion 104b may be formed on the conductive edge structure 104 that protrudes inward of the conductive edge structure 104. Here, the main board 102 may be mounted and fixed on the mounting portion 104 b. The placement portions 104b may be provided at both ends of the conductive edge structure 104 forming the joint portion 104a, respectively. That is, the placement section 104a may form a 1 st placement section 104b-1 on one of the two ends of the conductive edge structure 104 in between, and a 2 nd placement section 104b-2 on the other of the two ends of the conductive edge structure 104.
If the main board 102 is seated on the seating portion 104b, the 1 st connecting plate 117 may be electrically connected to the 1 st seating portion 104b-1 through the 1 st via hole 117a formed in the main board 102. The 2 nd connecting plate 119 is electrically connected to the 2 nd mounting portion 104b-2 through the 2 nd via hole 117b formed in the main plate 102.
The conductive edge structure 104 may be provided separately from the antenna 106. In this case, the conductive edge structure 104 may be provided to be coupled to the antenna 106 for use as a radiator. In this case, an effect is obtained that the radiation characteristic of the antenna 106 is expanded by the conductive edge structure 104.
Here, the 1 st matching circuit 111 may include: the electrical length of the 1 st matching circuit 111, the electrical length according to the antenna pattern of the antenna 106, the electrical length of the conductive edge structure 104, and the electrical length according to the coupling of the antenna 106 and the conductive edge structure 104 become the 1 st frequency band. The 2 nd matching circuit 113 may include: the electrical length of the 2 nd matching circuit 113, the electrical length according to the antenna pattern of the antenna 106, the electrical length of the conductive edge structure 104, and the electrical length according to the coupling of the antenna 106 and the conductive edge structure 104 become the 2 nd frequency band.
An antenna 106 may be provided within the mobile terminal 100 adjacent to the conductive edge structure 104. In this case, the antenna 106 may be provided separately from the conductive edge structure 104. For example, the antenna 106 may be isolated from the conductive edge construction 104 inside the conductive edge construction 104. An antenna 106 may be provided adjacent to and coupled to the conductive edge structure 104. That is, the antenna 106 may be coupled to power according to the conductive edge formation 104. The antenna 106 may use an FPCB (flexible Printed Circuit Board).
The antenna 106 may include a base component 106a and an antenna pattern 106 b. The base member 106a functions to support the antenna pattern 106 b. The base member 106a may be an insulating member having a fixed thickness. The antenna pattern 106b may be formed on one side (e.g., upper side) of the base member 106 a. In this case, the electromagnetic wave shielding material 108 may be bonded to the other surface (e.g., the lower surface) of the base member 106 a.
The antenna pattern 106b may be formed in a Loop (Loop) or Spiral (helical) shape, but is not limited thereto. Antenna pattern 106b may have an electrical length adjacent to the 2 nd frequency band (a frequency band higher than the 1 st frequency band). In this case, the 1 st matching circuit 111 and the 2 nd matching circuit 113 can easily adjust the frequency band of the antenna 106 to the 1 st frequency band or the 2 nd frequency band.
The electromagnetic wave shielding material 108 functions to shield electromagnetic waves generated from the antenna 106. The electromagnetic wave shielding material 108 may be attached to a lower portion of the antenna 106. The electromagnetic shielding material 108 may have a size corresponding to the size of the antenna 106.
The electromagnetic wave shielding material 108 may be a ferrite sheet or a metal magnetic sheet. The ferrite sheet can be produced by mixing ferrite powder and a binder resin, and as the ferrite powder, Mn-Zn ferrite, Ni-Zn-Cu ferrite, Mn-Mg ferrite, or the like can be used. The metal magnetic flakes may be formed by processing a strip or a ribbon of an Fe-based magnetic alloy or a Co-based magnetic alloy to be separated into a plurality of fine fragments (or a plurality of fragments). For example, Fe-based magnetic alloy may be Fe-Si-B alloy or Fe-Si-B-Co alloy, and Co-based magnetic alloy may be Co-Fe-Ni-Si-B alloy or Co-Fe-Cr-Si-B alloy, but not limited thereto.
According to the embodiment of the present invention, the 1 st band and the 2 nd band can be presented in the mobile terminal 100 through one antenna 106 and switch structure, so that the space utilization rate in the mobile terminal 100 can be improved, and the manufacturing cost of the mobile terminal 100 can be reduced. Here, since the MST band and the NFC band can be presented through one antenna 106, the mobile terminal 100 can support a settlement method according to MST communication and a settlement method according to NFC communication.

Referring to fig. 1 and 3, when the main board 102 is mounted on the mounting portion 104b formed on the conductive edge structure 104, the 1 st connecting plate 117 is electrically connected to the 1 st mounting portion 104b-1, and the 2 nd connecting plate 119 is electrically connected to the 2 nd mounting portion 104 b-2.
The 1 st matching circuit 111 may include a 1 st line pattern 111 a. One side of the 1 st line pattern 111a is connected to the 1 st connection board 117, and the other side of the 1 st line pattern 111a is connected to the switch section 115.
The 2 nd matching circuit 113 may include a 2 nd line pattern 113a, a 1 st matching element 113b, and a 2 nd matching element 113 c. One side of the 2 nd line pattern 113a is connected to the 2 nd link plate 119, and the other side of the 2 nd line pattern 113a is connected to the switching part 115. The 1 st and 2 nd matching elements 113b and 113c may be formed on the 2 nd line pattern 113a, respectively.
