Abstract

The invention discloses an antenna small panel, an antenna structure and a mobile terminal. The antenna small panel comprises a panel body, an antenna feed point and a radio frequency connector, wherein one surface of the panel body includes a copper-poured area, a wiring area and a clearance area which are arranged up and down, and the copper-poured area and the wiring area are arranged at the same side and are respectively adjacent to the clearance area; the antenna feed point is arranged in the clearance area; the radio frequency connector is arranged in the wiring area and is connected with the antenna feed point by virtue of a feed wire; and one side of the copper-poured area extends toward the clearance area to form an extended section, and the tail end of the extended section is connected with the feed wire. The invention aims at providing the antenna small panel, the antenna structure and the mobile terminal, so as to solve the problem that antenna performance at a certain sideis poor due to influence of the head and hands.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna plate, an antenna structure and a mobile terminal. Background technique [0002] Antennas are an important part of mobile terminal products. With the continuous improvement of mobile terminal performance and the continuous increase of functions, the requirements for antenna design have increased. [0003] Currently, mobile terminal antennas usually use IFA or PIFA antennas. The antenna feed point is often realized by a shrapnel, and is usually arranged at the bottom of the mobile terminal. In this case, the mobile terminal will be in a hand-held state or in a head-hand state. . For example, when a user uses a mobile terminal to make a call, the mobile terminal will be between the user's head and hands, and this state is called a head-hand state. When the mobile terminal is in the hand-held state or in any of the head-hand states, the performance of the antenna of the mobile ...
