Abstract

An antenna device of a portable terminal including conductive components is provided. The antenna device includes a first radiator connected to a power feeding unit of the portable terminal and a second radiator connected to each of the power feeding unit and a ground part of the portable terminal. At least one of the conductive components is connected to at least one the first radiator and the second radiator. The conductive components may be used as a radiator of the antenna device such that the antenna device may be easily installed within an inner space of a miniaturized and lightened portable terminal and the inner space of the portable terminal may be efficiently used.

First claim

What is claimed is:

1. An apparatus comprising:
a case forming at least part of an outer surface of the apparatus;
a circuit board housed in the case, the circuit board including a conductive layer formed thereon such that a slit is located between a first portion of the conductive layer and a second portion of the conductive layer, and that a feeding line connecting the first and second portions is located across the slit;
a ground portion connected to the first portion of the conductive layer;
a conductive component directly connected to the feeding line
and at least partially mounted on the second portion of the conductive layer; and
another conductive component at least partially mounted on the second portion of the conductive layer and connected to at least one portion of the case,
wherein the at least part of the case connected by the other conductive component and at least part of the second portion of the conductive layer are adapted to radiate using a power supplied via the feeding line.

2. The apparatus of claim 1 , wherein a first end of the feeding line is connected to the first portion, and a second end of the feeding line is connected to the second portion.

3. The apparatus of claim 1 , wherein the conductive component comprises a universal serial bus connector, a charge connector, an interface connector, an earphone-microphone socket, a storage medium socket, or any combination thereof.

4. The apparatus of claim 1 , wherein the feeding line comprises a capacitive coupling element or an inductive coupling element to be used to adjust a characteristic with respect to the radiating of the conductive component or the at least part of the second portion of the conductive layer.

5. The apparatus of claim 1 , wherein the case is substantially planar.

6. An apparatus comprising:
a cover forming at least part of a front or back surface of the apparatus;
a circuit board housed in the cover, the circuit board including a conductive layer formed thereon such that a slit is located between a first portion of the conductive layer and a second portion of the conductive layer, and that a feeding line connecting the first and second portions is located across the slit;
a ground portion connected to the first portion of the conductive layer;
a conductive component directly connected to the feeding line and at least partially mounted on the second portion of the conductive layer; and
another conductive component at least partially mounted on the second portion of the conductive layer and connected to at least one portion of the cover,
wherein the at least part of the cover connected by the other conductive component and at least part of the second portion of the conductive layer are adapted to radiate using a power supplied via the feeding line.
