Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the embodiment of the present invention provides a communication terminal, which can not only reduce the requirement of the antenna structure on the overall length and width of the communication terminal in the existing metal back shell communication terminal, which may easily cause the antenna resonant frequency to be too long or The problem of being too short can also reduce the impact of the user's head and hands on the communication terminal during use

Embodiment Construction

[0030] As mentioned in the background technology section, the full metal casing antenna device in the prior art uses a PIFA antenna. Since the PIFA antenna is very sensitive to the connection position between the feed source and the ground, the mobile communication terminal using this antenna structure has a large impact on the overall length and The width requirements are relatively high, otherwise, it is easy to cause the antenna resonant frequency to be too long or too short. Moreover, the mobile communication terminal using this antenna structure is greatly affected by the user's head-hand, and it is difficult to meet the index of the mobile communication terminal antenna performance in the head-hand test.

[0031] In view of this, an embodiment of the present invention provides a communication terminal, including:

[0032] The metal back shell arranged on the back of the communication terminal, the metal back shell includes a first back shell and a second back shell, ther...

Abstract

The embodiment of the invention discloses a communication terminal which comprises a metal back shell which comprises a first back shell and a second back shell. A gap is arranged between the first back shell and the second back shell and is filled with an insulation material. The communication terminal also comprises an excitation source which is electrically connected to the first back shell through a feed point, at least one first link member arranged on the first back shell, at least one second link member arranged on the second back shell, and a motherboard which is electrically connected to the first back shell through the first link member and is electrically connected to the second back shell through the second link member. Through adjusting the setting positions of the first link member and the second link member, the current path in an antenna system is changed, thus the resonant frequency of the antenna system is adjusted, the structure is simple, the adjustment is flexible, the problem of two long or too short of the antenna resonant frequency of an antenna system caused by high overall length and width requirements of a communication terminal in the prior art is solved, and the influence of user head and hands on the antenna performance of the communication terminal in the use process is reduced.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a communication terminal. Background technique [0002] With the continuous improvement of users' requirements for the appearance of mobile communication terminals, more and more mobile communication terminals with metal appearance appear on the market, but the all-metal back covers of most mobile communication terminals have many gaps or plastic areas. To meet its antenna performance requirements. There are only two slits on the metal back cover of a very small number of mobile communication terminals. However, the all-metal shell antenna device described in this patent application uses a PIFA antenna. Since the PIFA antenna is very sensitive to the connection position between the feed source and the ground, the mobile communication terminal using this antenna structure requires the overall length and width. Higher, otherwise, it is easy to cause the antenna resonant ...
