Problems solved by technology

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

[0026] 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.

[0027] 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 having the same. The antenna system comprises a metal back cover, wherein the metal back cover is divided into a first metal back cover, a second metal back cover and a third metal back cover, the left side region of the first metal back cover serves as a radiation main body of a first antenna, the second metal back cover serves as a main ground of the antenna system, a first antenna feed point is arranged on the left side region of the first metal back cover, the first antenna feed point is connected to a first feed source, the right side region of the first metal back cover serves as a radiation main body of a second antenna, a second antenna feed point is arranged on the right side region of the first metal back cover, and the second antenna feed point is connected to a second feed source. By adopting the antenna system and the communication terminal having the same, an IFA antenna and a LOOP antenna can be formed simultaneously, requirements for wideband antennas of the communication terminal are satisfied, and the loss of signals by hands when a user is holding the communication terminal can be further reduced.

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...
