Abstract

An FM transmission antenna device in a portable terminal is provided. In the FM transmission antenna device, an antenna pattern is attached to a surface of the portable terminal, an FPC extends from the antenna pattern, and a connector is provided at an end of the FPC, for connecting the FPC to an FM transmitter.

Claims

1. A frequency modulation (FM) transmission antenna device in a portable terminal, comprising:

an antenna pattern attached to a surface of the portable terminal;

a flexible printed circuit (FPC) that extends from the antenna pattern; and

a connector provided at an end of the FPC, for connecting the FPC to an FM transmitter.

2. The FM transmission antenna device of claim 1, wherein

the antenna pattern is attached onto a portion of an outer surface of the portable terminal, and further comprising a dummy cover for covering at least the portion of the outer surface of the portable terminal.

3. The FM transmission antenna device of claim 2, further comprising

a hole at the portion of the outer surface of the portable terminal, for allowing the FPC to be extended into the portable terminal through the hole.

4. The FM transmission antenna device of claim 1, further comprising

a speaker hole at a predetermined position of the outer surface of the portable terminal, wherein the antenna pattern is a loop antenna attached onto the outer surface of the portable terminal to surround the speaker hole.

5. The FM transmission antenna device of claim 1, wherein

the antenna pattern is a printed circuit pattern formed of a thin copper film and coated with an insulation material on both surfaces.

6. A portable terminal, comprising

a housing having an inner surface and an outer surface;

an antenna pattern attached to the outer surface of the portable terminal;

a flexible printed circuit (FPC) that extends from the antenna pattern;

a frequency modulated (FM) transmitter; and

a connector provided at an end of the FPC, for connecting the FPC to the FM transmitter.

7. The portable terminal of claim 6, further comprising

a dummy cover for covering at least the portion of the outer surface of the portable terminal.

8. The portable terminal of claim 6, wherein

the housing has a hole at the portion of the outer surface of the portable terminal where the antenna pattern is attached to allow the FPC to be extended into the portable terminal through the hole.

9. The portable terminal of claim 6, wherein

the housing has a speaker hole for receiving a speaker at a predetermined position on the outer surface of the portable terminal, and

the antenna pattern is a loop antenna attached onto the outer surface of the portable terminal to surround the speaker hole.

10. The portable terminal of claim 6, wherein

the antenna pattern is a printed circuit pattern formed of a thin copper film and coated with an insulation material on both surfaces.
