Problems solved by technology

[0003] At present, for the sake of appearance and integrity, most mobile devices choose metal casings to increase consumers' willingness to buy. However, antennas are placed in environments with a lot of metal, and the radiation efficiency is usually not good.
[0004] In the traditional all-metal environment, most of them use non-conductive foam or materials to process directly under the antenna, or suggest customers to clear the metal parts around the antenna so that the antenna can have enough radiation space, but there is no chance for customers to change the structure and materials. high

Embodiment Construction

[0010] see figure 1 As shown, the antenna 10 of the present invention is arranged on a metal casing 20, which includes a first substrate 11, an adhesive 12, a second substrate 13, a copper wire layer 14, an ink layer 15, a metal plating layer 16, a capacitor 17 and together Axis 18.

[0011] The first substrate 11 is made of FR4 (Fiberglass Reinforced epoxy resin) or BT (Bismaleimide-Triazine) material, and the first substrate 11 is directly disposed on the metal shell 20 . The second substrate 13 is made of PI (Polyimide), and the adhesive 12 adheres the second substrate 13 to the first substrate 11 . The second substrate 13 increases the clearance of the novel antenna 10 relative to the metal casing 20, the dielectric constant of the first substrate 11 is 4.4, the dielectric constant of the second substrate 13 is 3.6, and the dielectric constant of the second substrate 13 is lower than that of the first substrate. The substrate 11 is beneficial to increase the radiation ef...

Abstract

The invention relates to a novel antenna which comprises a first substrate arranged on a metal outer shell, adhesives, a second substrate, a copper wire layer, an ink layer and a metal coating. The second substrate is adhered to the first substrate through the adhesives, the copper wire layer is arranged on the first substrate, a part of the copper wire layer is covered by the ink layer, the other part of the copper wire layer is covered by the metal coating, the first substrate is made of the FR4 material, and the second substrate is made of the PI material. The clearance of the antenna relative to the metal outer shell is enlarged, and radiant efficiency of the antenna is improved.

Description

technical field [0001] The invention relates to an antenna, in particular to a novel antenna arranged on a metal casing. Background technique [0002] With the improvement of people's living standards and the development of communication technology, various multi-functional multimedia electronic portable mobile devices, such as mobile phones, tablet computers, notebook computers, etc., have become more and more popular in people's lives, and have become It is also more and more important, providing many conveniences for the daily life and use of consumers in general. [0003] At present, for the sake of appearance and integrity, most mobile devices choose metal casings to increase consumers' willingness to buy. However, antennas are placed in environments with a lot of metal, and the radiation efficiency is usually not good. [0004] In the traditional all-metal environment, most of them use non-conductive foam or materials to process directly under the antenna, or suggest ...
