Problems solved by technology

Because the metal shell has the advantages of high strength, not easy to be damaged, and has a metallic texture, many wireless communication device shells use metal shells to meet consumers' needs for product appearance, but metal shells are easy to interfere with the shielding set inside. The signal radiated by the antenna, resulting in poor radiation performance of the built-in antenna
In the prior art, in order to improve the radiation performance of the antenna, the antenna is generally arranged in the metal casing by opening holes or slots, and the antenna radiator is formed by using the metal casing to improve the radiation performance of the antenna. There is a possibility of spoiling the appearance of the metal case in one way or another

Description

technical field [0001] The invention relates to a wireless communication device, in particular to a wireless communication device with a metal casing. Background technique [0002] With the advancement of wireless communication technology, wireless communication devices are constantly developing towards a thinner and lighter trend, and consumers have higher and higher requirements on the appearance and performance of wireless communication devices. Because the metal shell has the advantages of high strength, not easy to be damaged, and has a metallic texture, many wireless communication device shells use metal shells to meet consumers' needs for product appearance, but metal shells are easy to interfere with the shielding set inside. The signal radiated by the antenna leads to poor radiation performance of the built-in antenna. In the prior art, in order to improve the radiation performance of the antenna, the antenna is generally arranged in the metal casing by opening hol...
