Abstract

An electronic device having a function of wireless transmission includes a wireless transceiving module, an accessing module and a shielding element that are disposed over a main board. The wireless transceiving module is used for transmitting a wireless signal. The accessing module is used for accessing an IC card having a radio frequency identification module. The shielding element is disposed between the wireless transceiving module and the accessing module and is electrically connected to a ground element of the main board. The shielding element is used for receiving the wireless signal to shield the radio frequency identification module.

Claims

1. An electronic device having a function of wireless transmission, comprising:

a main board comprising a ground element for connection to a reference potential;

a wireless transceiving module disposed over the main board for transmitting a wireless signal;

an accessing module disposed over the main board for accessing an integrated-circuit (IC) card when the IC card is electrically connected to the accessing module, wherein the IC card has a radio frequency identification module;

a processing unit disposed over the main board and electrically connected to the wireless transceiving module and the accessing module for controlling the wireless transceiving module and the accessing module; and

a shielding element disposed over the main board and between the accessing module and the wireless transceiving module, wherein the shielding element is electrically connected to the ground element for receiving the wireless signal to shield the radio frequency identification module of the IC card.

2. The electronic device of claim 1, wherein the shielding element comprises a grounding metal plate.

3. The electronic device of claim 1, wherein the shielding element is in a form of an antenna layout and is electrically connected to the ground element.

4. The electronic device of claim 1, wherein the wireless transceiving module has a first operating frequency, and the radio frequency identification module has a second operating frequency lower than the first operating frequency.

5. The electronic device of claim 4, wherein the range of the first operating frequency is from about 380 MHz to about 1900 MHz.

6. The electronic device of claim 5, wherein the second operating frequency is about 13.56 MHz.

7. The electronic device of claim 4, wherein the wireless transceiving module comprises a global system for mobile communications (GSM) wireless transceiving module.

8. The electronic device of claim 4, wherein the shielding element has a width matching the wireless signal so that the shielding element serves as a receiving antenna for the wireless signal.

9. The electronic device of claim 8, wherein the shielding element has a resonance frequency that approximately equals the first operating frequency.

10. The electronic device of claim 4, wherein the shielding element has a shape matching the wireless signal so that the shielding element serves as a receiving antenna for the wireless signal.

11. The electronic device of claim 10, wherein the shielding element has a resonance frequency that approximately equals the first operating frequency.

12. The electronic device of claim 1, wherein an interval between the shielding element and the wireless transceiving module is greater than an interval between the shielding element and the accessing module.

13. The electronic device of claim 1, wherein the accessing module is used for accessing data stored in the IC card, and the wireless transceiving module is used for transmitting the wireless signal having the stored data.
