Abstract

The invention provides a manufacturing process of a mobile phone built-in printed antenna, and the manufacturing process comprises the following steps of: carrying out injection moulding on plastic raw materials to form a basic shape of the mobile phone built-in printed antenna, printing conductive ink at an appointed position on the plastic surface of the injection moulded antenna model by using a mobile printing process so as to prepare for the next copper film electroplating, electroplating a copper film at an appointed position on the plastic surface of the printed plastic antenna model by using an electroplating process to ensure that the antenna has a conduction function and a signal reception function, and electroplating nickel on the outer surface of the mobile phone antenna electroplated with the copper film except for the external-connection conduction positions of the anode and cathode end points of the built-in antenna so as to protect the electroplated copper film layer. Moreover, gold plating can be carried out at the external-connection conduction position of the grounding end point of the built-in antenna and actually required color can be coated on the surface of the electroplated built-in antenna. According to the manufacturing process, the antenna gain and the bandwidth are not reduced, the signal strength is good and the production cost is reduced.

Description

technical field [0001] The application of the present invention relates to a manufacturing process of an antenna, especially a manufacturing process of a small-sized built-in printed antenna applied to a wireless terminal device. Background technique [0002] With the rapid development of wireless communication technology, mobile phones as wireless communication terminals are also developing towards the direction of miniaturization and diversified functions. Therefore, the size and weight of antennas (including radiators and floors), which are important components of mobile phones, also need to be reduced accordingly to meet the requirements for miniaturization of terminal equipment. [0003] At present, there are mainly two types of mobile phone antennas: built-in and external antennas. The antennas are installed as far away from the ground and buildings as possible. When the antenna is close to the reference ground, most of the energy will be concentrated between the anten...
