Problems solved by technology

[0003] In order to improve and enhance the overall firmness of the product, more and more mobile terminal devices such as smartphones currently use metal casings, such as metal back covers or metal frames, and metal casings can shield or absorb electromagnetic waves to a certain extent. The problem of narrow frequency band and low efficiency With the development of mobile communication technology, mobile terminal equipment needs to cover more and more modes, including GSM / DCS / PCS / WCDMA / TD-SCDMA / LTE, etc. Different mobile communication modes use different frequency band
[0004] In the related technology, the mobile terminal equipment needs to segment the metal casing or make the antenna not surrounded by the metal casing through special design. Affect the overall aesthetics of mobile terminal equipment
