Embodiment Construction

[0019] see figure 1 , which is a structural schematic diagram of Embodiment 1 of the printed mobile phone antenna of the present invention. As shown in the figure: it includes a mobile phone casing 1 and a printed circuit board 2 located in the casing 1. One end of a metal shrapnel 3 contacts the printed circuit board 2, and the other end extends through the casing 1 (such as: the back cover) and Attached to the outer surface of the case 1, the metal shrapnel 3 and the mobile phone case 1 can be molded. A printed metal layer 4 is pasted on the outer surface of the casing 1 (such as the back cover) and the metal dome 3 (such as screen printing), the printed metal layer 4 can be made of metal materials such as copper or nickel, and the printed The metal layer 4 is covered with a printed protective layer 5, which is used to protect the printed metal layer 4 from damage and prolong the service life of the product.

Abstract

The invention relates to an antenna of a mobile communication terminal product, and particularly relates to a printed mobile phone antenna. The printed mobile phone antenna comprises a mobile phone shell (1) and a printed circuit board (2) located in the shell (1). The characteristics lie in that the printed mobile phone antenna is provided with a metal elastic piece (3), one end of the metal elastic piece (3) is contacted with the printed circuit board (2), the other end of the metal elastic piece (3) penetrates through the shell (1), extends and is attached to the outer surface of the shell (1), a printed metal layer (4) is attached to the outer surface of the shell (1) and the metal elastic piece (3). The structure provided by the invention mainly solves a technical problem that existing mobile phones with external antennas need to perform mould opening for manufacturing the external antennas which increases the size of the mobile phones easily, and solves a technical problem that influences are imposed on the radio frequency (RF) efficiency by built-in arrangement of antennas of mobile phone antennas with built-in antennas at the same time. In addition, the manufacturing cost is low.

Description

technical field [0001] The invention relates to an antenna of a mobile communication terminal product, in particular to a printed mobile phone antenna. Background technique [0002] Existing mobile phone antennas are generally divided into two types: external and built-in. [0003] Chinese utility model patent specification (authorized announcement number: CN2511011Y) discloses an external mobile phone antenna, which includes an antenna section that is socketed by a screw rod, and a connector that is movably matched to the outermost antenna section. The antenna section of the first layer is an elastic anti-bending tube formed by coiling elastic steel strips, and a protective film is provided on its outer wall. It has the advantages of strong bending resistance, difficult deformation, and easy pulling of the antenna. However, such an external antenna mobile phone needs to open a mold for the manufacture of the external antenna, and the use of this external antenna not only ...
