Problems solved by technology

The reliability of antenna performance is reduced, and the complexity of debugging is increased; moreover, active devices such as radio frequency switches added to the feeder line of the antenna will introduce losses and reduce antenna performance. At the same time, the introduction of such active devices greatly increases manufacturing cost

Abstract

The invention relates to a non-breakpoint metal frame based mobile phone antenna. The mobile phone antenna structure comprises a completely-closed metal frame and a main board arranged in the metal frame, wherein a main antenna clearance region, a sub antenna clearance region and a three-into-one antenna clearance region are formed between the closed metal frame and the main board; and a main antenna feeding point, a sub antenna feeding point and a three-into-one antenna feeding point are arranged in the corresponding main antenna clearance region, the sub antenna clearance region and the three-into-one antenna clearance region respectively; the feeding points are electrically connected with the metal frame through connecting points respectively; and the three side edges of the closed metal frame are electrically connected to the corresponding side edges of the main board through grounding points. According to the mobile phone antenna, the metal frame is adopted for radiation, so that the complexity of the mobile phone structure is effectively reduced, the cost of the mobile phone is lowered, and the performance of the antenna is improved; and in addition, the mobile phone antenna is simple and attractive in structure and excellent in performance, and can be widely applied to the mobile phones with the completely-closed metal fames, as well as can satisfy the high-quality demands of the mobile phones.

Description

technical field [0001] The invention relates to a mobile phone antenna structure, in particular to a mobile phone antenna based on a non-breakpoint metal frame, that is, an antenna structure in which the metal frame is a complete metal frame, and belongs to the technical field of electronic information. Background technique [0002] With the development of electronic information technology, mobile terminals, that is, computer equipment used in mobile, are also called mobile communication terminals, and in most cases refer to mobile phones or smart phones with multiple application functions. The performance requirements for mobile phones will also become higher and higher. In order to improve the hand feel of mobile phones, more and more metal frame design structures are used on mobile phones. This metal frame structure has the advantages of good hand feeling and ultra-thin body. To comply with this industrial design, a metal frame is usually used as the radiator of the anten...
