Abstract

The invention provides a cover having a metallic grid structure and a method for manufacturing the cover. The cover includes a pattern portion formed of a metallic material, in which a plurality of patterns are independently disposed spaced apart from each other and an injection portion disposed between pattern portions to connect the pattern portions, the injection portion being formed of a non-metallic material. The method includes forming a pre-pattern portion including patterns in a regular or irregular form and a bridge connecting the patterns on a metallic plate, forming the injection portion on the pre-pattern portion by insert-injection or thermo-compression press, and removing the bridge.

Description

technical field [0001] The present invention generally relates to a portable terminal device, and more particularly, to a portable terminal device capable of reducing signal loss when performing Long Term Evolution (LTE) service to improve antenna reception performance. Background technique [0002] In general, portable terminal devices refer to devices that allow users to enjoy various contents while carrying them, such as portable communication devices, MP3 players, portable multimedia players, e-books, and the like. [0003] The casing of the portable terminal device can be visually inspected by the user, and it is natural for the user to select a portable terminal device having an elegant design and a high-quality appearance among various portable terminal devices having similar functions. Particularly, with the recent popularization of bar-type portable terminal devices, a large display screen is provided on a front surface of the portable terminal device, and a battery...
