Description

Antenna unit for portable electronic devices

The present invention relates to an antenna unit applied to a portable electronic device such as a mobile terminal or a wearable terminal, and more particularly, an antenna pattern unit for NFC for short-range wireless communication and/or an antenna pattern unit for WPT for wireless charging. It relates to an antenna unit of a portable electronic device having directivity in a direction.

Recently, an antenna unit applied to portable electronic devices such as smart phones or wearable terminals (e.g., smart watches) is a flexible circuit board (FPCB) made of synthetic resin such as polyimide (PI) or PET, and a conductor such as copper foil in a loop form. Patterning or using conductive ink to form a loop-shaped metal pattern on the flexible circuit board, while providing a connection terminal for electrical connection with the main circuit board of the electronic device on the end side of the flexible circuit board.

The conductor or metal pattern constituting the loop form is an antenna pattern part formed on one surface and/or the other surface of the flexible printed circuit board, and the antenna pattern part is an antenna pattern part for magnetic secure transmission (MST), wireless It includes an antenna pattern part for charging (Wireless Power Consortium (WPC)) and an antenna pattern part for Near Field Communication (NFC), and the MST antenna pattern part, the WPC antenna pattern part, and the NFC antenna pattern part The antenna pattern unit may be simultaneously applied or selectively applied according to the portable electronic device.

However, when only the NFC antenna pattern part P1 is applied to the portable electronic device, as shown in the attached FIG. 1, the NFC antenna pattern part P1 mounted on one surface of the substrate 100 is a shielding material (eg; Nanocrystal, Ferrite, Metal-polymer, Amophous, etc.) (200) is located on one side or the other side and directs only one direction. Regarding the direction toward which the radiation performance of the NFC antenna pattern part (P1) is directed, Although it is high, the radiation performance is degraded for other directions that are not directed, and the radiation performance of the left and right sides is also reduced while being blocked by the shielding material 200 .

Therefore, when the NFC antenna pattern part P1 is applied to a smart watch, which is a smartphone or a wearable terminal, the main circuit board 300 as shown in FIG. 2 attached to the direction the NFC antenna pattern part P1 is directed ), and portable electronic devices such as smartphones are free to change their location, but in the case of a smart watch, short-range wireless communication using the NFC antenna pattern part (P1) properly while worn There was a problem that couldn't be done.

That is, when the smart watch is worn, the user's wrist is located in one direction and the main circuit board 300 is located in the other direction, and the radiation performance of the NFC antenna pattern part (P1) is deteriorated, resulting in short-range wireless It was inevitable that there would be many errors in communication.

On the other hand, in the case of applying the antenna pattern part P1 for NFC and the antenna pattern part P2 for WPC to the portable electronic device, as shown in the attached FIG. 3, one side of the shielding material 200, that is, the substrate ( 100), since the NFC antenna pattern part (P1) and the WPC antenna pattern part (P2) are formed on one side, this also had to be a structure directed only in one direction, and accordingly, the NFC antenna pattern part (P1) The radiation performance of the WPC antenna pattern part P2 is high for one direction directed, but the radiation performance is lowered for the other direction that is not directed, and the radiation performance of the left and right is also blocked by the shielding material 200 As it progresses, it is bound to deteriorate.

Therefore, when the NFC antenna pattern part P1 and the WPC antenna pattern part P2 are applied to a smartphone or a wearable terminal smart watch, the NFC antenna pattern part P1 and the WPC antenna pattern part In the direction that (P2) is directed, it is inevitable to be placed on the main circuit board 300 as shown in attached FIG. In the worn state, short-range wireless communication using the NFC antenna pattern part P1 did not occur properly.

That is, when the smart watch is worn, the user's wrist is located in one direction and the main circuit board 300 is located in the other direction, and the radiation performance of the NFC antenna pattern part (P1) is deteriorated, resulting in short-range wireless It was inevitable that there would be many errors in communication.

Accordingly, conventionally, as shown in FIG. 4, the substrate 100 having the WPC antenna pattern part P2 mounted thereon is placed on one surface of the shielding material 200, and the other surface of the shielding material 100 has an antenna pattern for NFC. The substrate 100' on which the part P2 is mounted is separated to be disposed.

That is, in the smart watch, the orientation direction of the antenna pattern part P2 for WPC is directed toward the wrist, which is the back surface of the smart watch, with the shielding material 200 interposed therebetween, and the orientation direction of the antenna pattern part P1 for NFC is configured separately to face the direction of the display window, which is the flat surface of the smartwatch.

However, the separation structure of the antenna pattern parts P1 and P2 as described above makes it difficult to slim down the thickness of the portable electronic device due to the mounting space of the main circuit board 300, and inevitably requires a lot of cost due to parts and mounting work. There were no structural disadvantages.
