Abstract

The present invention relates to a multi-band antenna and, more particularly, to a sub multi-band antenna, in which a planer conducting part, which has a plurality of protruding portions, is inserted into a depression, which is formed on the surface of a body part formed through injection molding using a mold having a specific shape to surround first and second wire members, and the fitting depression of a fastening part, which is formed through the cutting or die casting of a metal material, and to a sub-band built-in chip antenna, in which sub radiation patterns having a predetermined length are formed on the interior surface of a body part, which is formed through injection molding using a dielectric material or is formed of a layered substrate a dielectric material.

Description

technical field [0001] The present invention relates to a multi-band antenna, and more particularly, to a submulti-band antenna in which a planar-shaped conductive portion having a plurality of protrusions is inserted into a recess formed on a surface of a body portion and passed through In the fitting recess of the fastening portion formed by cutting or die-casting a metal material, the body portion is formed by injection molding using a mold having a specific shape to surround the first and second wiring members, thereby increasing the number of resonance frequency bands, And wherein the corresponding portions of the first and second wiring members protrude outside the body portion in the longitudinal direction of the body portion, thereby achieving a good radiation pattern and being usable in a plurality of resonant frequency bands, and also relates to a sub-band built-in chip antenna ( sub-band built-in chip antenna), wherein a sub-band pattern having a predetermined lengt...
