Description

Wearable Electronic Device Including Communication Circuit TECHNICAL FIELD

Various embodiments of the present disclosure relate to a structure of a wearable electronic device that performs communication using a communication circuit.

Electronic devices have a communication function and are widely used by many people because their size is widely used in a portable form. In recent years, the form of electronic devices is developing into a form worn or worn on a wrist or the like (wearable form). The appearance of such electronic devices is also being transformed into various forms. Accordingly, arrangements and shapes of device elements mounted on conventional electronic devices are required in various forms.

A short-range communication circuit for performing short-range communication, for example, NFC (near field communication) communication in a conventional electronic device, is located on the rear side of the electronic device. Since the transmittance of radio waves is weak due to the frequency characteristics of short-range communication, the short-range communication circuit is located as far outside the electronic device as possible. Since the short-range communication circuit is located in front of the electronic device, performance degradation due to interference with other communication circuits has become a problem. Accordingly, the short-range communication circuit is provided in the rear case of the electronic device or built into the battery of the electronic device.

However, it is inconvenient in use to apply the positional characteristics of the short-range communication circuit in the electronic device as it is to the wearable electronic device. For example, when an NFC communication circuit is located on the rear side of a smart watch, the user has the inconvenience of having to detach the smart watch from the wrist whenever NFC communication is used.

Various embodiments of the present disclosure may provide the wearable electronic device capable of using short-range communication while wearing the wearable electronic device on a human body.

In addition, various embodiments of the present invention may support wireless charging using other communication circuits. In this case, the wearable electronic device may include the other communication circuit at a location where a performance deterioration problem due to interference with the short-range communication does not occur.

An electronic device (for example, a wearable electronic device) according to an embodiment of the present invention includes: an outer housing including a first surface and a second surface facing the opposite side of the first surface; A printed circuit board disposed in a space formed between the first and second surfaces and forming a surface substantially parallel to the first surface; A display disposed between the first surface and the printed circuit board; An antenna pattern disposed between the display and the second surface; And at least one communication circuit electrically connected to the antenna pattern.

The electronic device according to an embodiment of the present invention may further include a metal pattern disposed between the printed circuit board and the second surface.

The electronic device according to an embodiment of the present invention may further include a charging circuit electrically connected to the metal pattern.

According to various embodiments of the present disclosure, the wearable electronic device may provide a communication function capable of performing short-range communication without leaving a user.

In addition, according to various embodiments of the present disclosure, the wearable electronic device may include a wireless charging pad and may conveniently perform charging without a separate plug-in connector.
