Abstract

An antenna structure includes a metal member, a first antenna, a second antenna, a third antenna, and a fourth antenna. A gap is defined on the metal member to divide the metal member into a first frame assembly and a second frame assembly. The first frame assembly and the second frame assembly cooperatively form a receiving space for accommodating at least one electronic element. The first antenna, the second antenna, the third antenna, and the fourth antenna are received in the receiving space. The first antenna is electronically connected to the first frame assembly of the metal member. The third antenna and the fourth antenna are both electronically connected to the second frame assembly of the metal member.

Description

technical field [0001] The present invention relates to an antenna structure, in particular to an antenna structure using a metal appearance part and a wireless communication device using the antenna structure. Background technique [0002] With the development of wireless communication products, the design of each product is developing towards a thinner and lighter trend, and consumers have higher and higher requirements for product appearance. Due to the advantages of metal casings in appearance, structural strength, and heat dissipation effects, communication products with metal casings have developed rapidly. However, when the metal casing takes up a lot of space of the wireless communication product, it is easy to affect the characteristics of the antenna of the wireless communication product. Therefore, how to maintain the characteristics of the antenna under the metal appearance structure is an important issue faced by the antenna design. Contents of the invention ...
