Description
The present invention relates to a method of manufacturing an antenna for a mobile communication terminal having a metal frame, an antenna for the mobile communication terminal manufactured thereby, and a mobile communication terminal having the same.
A mobile communication terminal is a portable device having a function of storing information, inputting / outputting information, and data, centering on a call / message transmission / reception function, while being portable. Thanks to the rapid development of information technology and electronic industry, mobile communication terminals are becoming one of the essential personal personal items of modern people equipped with various functions such as cameras, music and video playback, games, and TV.
An external antenna, which is exposed to the outside of the terminal, was developed first, but the internal antenna mounted on the mobile communication terminal has been replaced with an internal antenna having fewer problems of damage while improving the beauty. Various types of built-in antennas have been developed depending on the type of antenna, manufacturing method, material, position, and the like. In accordance with miniaturization of a terminal, an antenna embedded therein must satisfy complicated conditions such as securing a space and a space that can realize communication quality from the viewpoint of design, overcoming influences from other parts becoming closer and becoming higher density, and regulating electromagnetic waves The difficulty also increases.
In recent years, a dielectric carrier or a support for fixing the built-in antenna is separately provided inside the cage of the terminal. In recent years, the antenna is installed directly in a case or a frame of the mobile terminal, thereby reducing the installation space or volume and increasing the component density. In the method of forming the antenna pattern, direct printing or vapor deposition is also used in order to reduce the thickness and simplify the manufacturing process. In order to secure a certain distance from the circuit board, the antenna pattern may be located on the opposite side of the case or the frame. In order to connect the antenna pattern to the circuit board, a conductor that passes through the structure supporting the antenna pattern is required. In order to install the conductor through the case, another metal may be injected into the case and insert, a metal pin may be press-fitted, or printing or plating may be performed on the inner wall of the through hole for conduction.
A slim design of the mobile communication terminal and a design that wraps the frame by using a metallic ring to provide mechanical rigidity or emphasize individuality according to the display conversation has been proposed. However, the metal rim acts as a weak point that imposes restrictions on the mounting area or design of the antenna, which is becoming increasingly narrow.
