Problems solved by technology

[0003] However, when the near-field communication antenna is integrated in an electronic device, the high-frequency signal generated by it may be affected by the metal casing or other metal components of the electronic device, causing the signal that the near-field communication antenna can send and receive to weaken or even fail. send and receive signals
In order to avoid the influence of these components, the location and area of ​​the NFC antenna configuration on the electronic device are quite limited
In addition, due to the limitation of the area, the size of the NFC antenna is getting smaller and smaller, and the difference in the size of the antenna will lead to weak magnetic field coupling, which in turn inhibits the ability of the NFC antenna to transmit energy.

Abstract

An electronic device is provided. The electronic device includes a casing, a display module, and a communication module. The casing includes a first surface and a second surface. The display module is disposed on the first surface and has a display region. The communication module includes a first antenna module and a second antenna module. The first antenna module is disposed close to the display module and is corresponding perpendicularly to at least one part of the display region. The second antenna module is disposed close to the second surface. The communication module selectively receives and transmits a wireless signal along an outward direction extending from the first surface via the first antenna module or along an outward direction extending from the second surface via the second antenna module.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to an electronic device capable of performing Near Field Communication (NFC). Background technique [0002] Near field communication is a short-range high-frequency wireless communication technology. It uses the principle of magnetic field induction to enable electronic devices to realize interconnection within a short distance. Since near-field communication is very convenient for data transmission, management and storage, and near-field communication tends to conduct short-distance transactions, it is suitable for exchanging important data such as financial information or personal information. Many consumer electronic products such as mobile phones, PDAs (Personal Digital Assistant, PDA), tablet computers, notebook computers, etc., have been equipped with NFC chips for identity recognition, data exchange or transaction payment. . [0003] However, when the near-field communic...
