Problems solved by technology

However, this method needs to add one or more connection points between the metal frame and the ground plate, and the production of these connection points increases the processing difficulty of the metal frame
At the same time, whether these grounding points are in good contact with the main board will directly affect the performance of the antenna, reducing the reliability of the antenna performance and increasing the complexity of debugging; Introduce loss, reduce antenna performance, and the introduction of such active devices greatly increases manufacturing costs

Embodiment 1

[0030] Please refer to image 3 , Embodiment 1 of the present invention is: an antenna structure based on a complete metal frame, suitable for electronic devices such as mobile phones and palmtop computers, including a complete metal frame 1, a first antenna 6 and a second antenna 7, and also includes a The main board 2, the main board 2 is set in the metal frame 1, the metal frame 1 is not grounded, that is to say, the metal frame is not connected to the ground point, and the top of the metal frame 1 is provided with a clearance area 5, The height of the clearance area 5 is more than 5mm, and the first antenna 6 and the second antenna 7 are arranged in the clearance area 5 and are not connected; optionally, the first antenna 6 and the second antenna 7 are connected to the metal frame 1 to connect or not to connect.

[0031] The antenna structure also includes a first feed point and a second feed point, the first antenna 6 is connected to the main board 2 through the first fe...

Embodiment 2

[0038] Please refer to Figure 6 , Embodiment 2 of the present invention adds an LTE antenna 8 on the basis of Embodiment 1.

[0039] The LTE antenna 8 is also arranged in the clear area 5, the LTE antenna 8 includes a first branch 81 and a second branch 82, and the end of the first branch 81 and the end of the second branch 82 and the metal frame 1 The distance between them is 0-0.6mm; for example, the end of the first branch 81 is routed along the side of the metal frame 1 and parallel to the side of the metal frame 1, and the distance between it and the metal frame 1 is 0.3mm, The end of the second branch 82 runs along the top of the metal frame 1 and is parallel to the top of the metal frame 1 , and the distance between the second branch 82 and the metal frame 1 is 0.6 mm.

[0040] The other end of the opposite end of the two branches of the LTE antenna 8 is connected to the main board 2, and the two can be connected to the main board 2 respectively, or can be connected t...

Abstract

The invention discloses an antenna structure based on a complete metal frame. The antenna structure comprises the complete metal frame, a first antenna and a second antenna. The top end in the metal frame is provided with a clearance area. The first antenna and the second antenna are arranged in the clearance area. The sizes of the first antenna and the second antenna are respectively smaller than a quarter of the operating wavelength thereof. The mobile phone antenna structure is characterized in that special processing on the metal frame is not needed, the integrity of the metal frame is ensured, the machining is simple, and the antenna structure is simple and is convenient to debug.

Description

technical field [0001] The present invention relates to an antenna structure, in particular to an antenna structure based on a complete metal frame. Background technique [0002] At present, more and more mobile terminals adopt metal frame design, which has achieved the advantages of good user feeling and ultra-thin body. In order to comply with this industrial design, a metal frame is usually used as the radiator of the antenna. [0003] a method such as figure 1 As shown, two gaps 3 are opened on both sides of the metal frame 1, so that the complete metal frame 1 is divided into two parts, and the lower part is used as a part of the radiator of the antenna. However, this method destroys the integrity of the metal frame 1, making it actually processed as two parts, which increases the difficulty of processing; and the distance and relative distance between the metal part as the radiator and another metal part after interruption The change of the position has a great infl...
