However, the three-stage type has gradually lost its appearance value due to its extremely high prevalence rate, and the three-stage metal back cover gives users a strong sense of separation; the antenna of the communication terminal without slots or no slits The performance is greatly limited. Looking at the market, the antenna performance of communication terminals with this appearance is not ideal.

Embodiment Construction
[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component,...

The invention provides an antenna system and a communication terminal with the antenna system. The antenna system comprises a metal back cover, wherein the metal back cover is arranged on the communication terminal, and is at least divided into a first metal back cover and a second metal back cover; the first metal back cover is used as an antenna radiation body of the antenna system, and the second metal back cover is used as a main ground of the antenna system; an antenna feed point is arranged on the first metal back cover, and is electrically connected with a feed source on a PCB (printed circuit board) of the communication terminal. The antenna system has the advantages that the requirement of the wide-frequency band antenna by the communication terminal is met, and the loss of signals by a human hand is reduced when a user holds the communication terminal.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an antenna system and a communication terminal with the antenna system. Background technique [0002] With the continuous improvement of users' requirements on the appearance of communication terminals, more and more communication terminals with metal appearance appear on the market, but the metal back cover of most communication terminals is three-stage, and the metal back cover of very few communication terminals is Not slotted or slotted. However, the three-stage type has gradually lost its appearance value due to its extremely high prevalence rate, and the three-stage metal back cover gives users a strong sense of separation; the antenna of the communication terminal without slots or no slits The performance has been greatly limited. Looking at the market, the antenna performance of the current communication terminal with this appearance is not ideal. Content...
