Problems solved by technology

This technology has many restrictions on the material of the bracket. Specifically, not all materials are suitable for LDS technology, so naturally it poses a challenge to the antenna design of a mobile phone with a glass shell.
In addition, the LDS antenna formed on the plastic bracket is usually placed inside the phone body, and the RF (Radio Frequency) performance of the antenna cannot be maximized due to the influence of surrounding components.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, a mobile device includes a main body, a circuit board disposed in the main body, and a glass back cover 101 connected to the main body. The mobile devices mentioned in the present invention may be electronic devices such as mobile phones and tablet computers. The glass back cover 101 is provided with an LDS antenna system, the LDS antenna system is pasted on the LDS coating 102 on the surface of the glass back cover 101 and the LDS antenna is formed on the surface of the LDS coating 102 using LDS technology. The LDS antenna is electrically connected to the circuit board. In a preferred embodiment of the present invention, the LDS antenna includes a GPS antenna 103 , an NFC antenna 104 , and a WIFI antenna 105 . In other preferred embodiments, a main antenna or other types of antennas may also be included. The LDS co...

Abstract

The invention provides mobile equipment. The mobile equipment comprises a main body, a circuit board arranged in the body as well as a rear glass cover connected with the main body, wherein the LDS antenna system is arranged on the rear glass cover and comprises an LDS coating attached to the surface, facing the inside of the main body, of the rear glass cover as well as an LDS antenna formed on the LDS coating with an LDS technique, and the LDS antenna is electrically connected with the circuit board. The LDS coating on the surface of the rear glass cover makes possible the formation of the antenna on a mobile phone provided with the rear glass cover with the LDS technique, and the RF (radio frequency) performance of the antenna can be maximized due to the fact that the antenna is located on the rear glass cover.

Description

【Technical field】 [0001] The invention relates to the field of mobile communication, in particular to an LDS antenna which is applied to a mobile terminal and formed by using the LDS technology. 【Background technique】 [0002] With the development of mobile phones towards thinner, metallized and glassy casings, the design requirements for mobile phone antennas are also getting higher and higher. [0003] Laser Direct Structuring (Laser Direct Structuring) refers to using a computer to control the movement of the laser according to the trajectory of the conductive pattern, projecting the laser onto the molded three-dimensional plastic device, and activating the circuit pattern within a few seconds. For the design and production of mobile phone antennas, it means that on the formed plastic bracket, the metal pattern is directly formed on the plastic bracket by using laser laser technology. This technology has many restrictions on the material of the bracket. Specifically, not...
