Abstract

The invention provides a wireless communication device comprising a metal shell, a substrate and a current feed-in part. The shell is provided with a first trench and a second trench communicated with each other. The current feed-in part is electrically connected with the substrate and used for acquiring current from the substrate. The shell is coupled to the current feed-in part, so that the first and second trenches can sense the current and trigger out corresponding resonant modes, and the wireless communication device can transmit and receive wireless signals having first and second center frequencies. The wireless communication device has the advantages that the metal shell is fully utilized as an antenna, transceiving efficiency of the antenna is improved effectively, and miniaturization development of the wireless communication device is benefited.

Description

technical field [0001] The present invention relates to a wireless communication device. Background technique [0002] In a wireless communication device, the antenna device used to transmit and receive radio waves to transmit and exchange radio data signals is undoubtedly one of the most important components in the wireless communication device. At present, some wireless communication devices on the market use a metal casing to increase the texture. However, the metal casing often forms a large grounding point with the main board of the wireless communication device, resulting in a decrease in antenna efficiency. Therefore, how to improve the transmitting and receiving efficiency of the antenna of the wireless communication device with a metal casing has become the biggest challenge for various antenna manufacturers. Contents of the invention [0003] In view of the above circumstances, it is necessary to provide a wireless communication device with a metal casing and hi...
