Embodiment Construction

[0016] see figure 1 and figure 2 , in the first embodiment of the present invention, an antenna structure 100 is provided, which is applied to a wireless communication device 200 having a metal casing such as a mobile phone and a tablet computer.

[0017] The wireless communication device 200 includes a circuit board 220 and a metal shell 240. A feed point 222 and a ground point (not shown) are set on the circuit board 220. The feed point 222 is used to feed the antenna structure 100 current, the circuit board 220 is set in the metal shell 240, and the metal shell 240 is electrically connected to the grounding point of the circuit board 220 through a known mechanical connection method such as screw locking with the circuit board 220, so as to provide the antenna structure 100 Provides system ground.

[0018] The antenna structure 100 includes a first antenna 30, a second antenna 50 and a metal part 70, the first antenna 30 and the second antenna 50 are arranged on a circuit...

Abstract

The present invention provides an antenna structure, which includes a first antenna, a second antenna and a metal part, the second antenna includes a first part, a second part and a third part connected in sequence, and the metal part includes a first metal frame , the first part and the third part of the second antenna are arranged at intervals from the first antenna, the second part and the third part of the second antenna are arranged at intervals, the first part and the third part of the second antenna are both Connect with the first metal frame. The present invention also provides a wireless communication device with the above-mentioned antenna structure. The metal parts of the wireless communication device are integrated into a part of the antenna structure, which avoids the shielding effect caused by the metal shell on the antenna, reduces the size and occupied space of the antenna, and achieves The effect of reducing costs. At the same time, another advantage of the antenna structure is that it can maintain the characteristics of the antenna and maintain the integrity of the overall appearance design of the product without destroying the structure of the metal shell.

Description

technical field [0001] The invention relates to a wireless communication device and its antenna structure, in particular to a wireless communication device with a metal shell and its antenna structure. Background technique [0002] With the upsurge of wireless communication products, the design of various communication products is developing towards the trend of light and thin, and consumers have more and more stringent requirements on product appearance. Because wireless communication devices with metal casings have great advantages in terms of appearance, structural strength, and heat dissipation effect, the communication products with metal casings are booming under the consideration of appearance and mechanism design. The antenna device is one of the important components in wireless communication. However, the metal shell is easy to cause shielding effect on the antenna and affect the characteristics of the antenna. How to maintain the characteristics of the antenna unde...
