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
[0031] 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.
[0032] 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,...

Abstract
The invention provides an antenna system and a communication terminal with the antenna system. The antenna system comprises an all-metal back cover, a coupling feed unit, a radiation unit, a polymorphic aperture tuning unit and a ground reflection unit, wherein the all-metal back cover, the coupling feed unit, the radiation unit, the polymorphic aperture tuning unit and the ground reflection unit are arranged on the communication terminal. The coupling feed unit is coupled to the radiation unit which is used for radiating or receiving a radio frequency signal. The radiation unit is connected with the left metal frame of the communication terminal to realize grounding. The polymorphic aperture tuning unit is used for tuning a multi-channel antenna. One end of the polymorphic aperture tuning unit is in physical contact with the radiation unit, and the other end is grounded. The ground reflection unit is used to ground the antenna system. According to the invention, through coupling feed and a polymorphic aperture tuning circuit, the communication terminal can acquire a better broadband antenna radiation performance.
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...
