Abstract
A headset for a mobile communication terminal is disclosed. The headset comprises a main body and a RF module printed circuit board (PCB) housed within it. A microphone is also housed within the main body and connected to the RF module PCB. A guide piece housing an antenna, which is connected to the RF module PCB, is connected to the main body on one end and has an opening on the second end. Finally, a speaker is connected to the main body opposite the guide piece.

A headset for a mobile communication terminal comprising:
- a main body having first and second ends;
- a RF module printed circuit board (PCB) housed within the main body;
- a speaker connected to the first end of the main body;
- a microphone housed within the main body and connected to the RF module PCB;
- a guide piece having first and second ends, wherein the first end is secured to the second end of the main body;
- an opening situated on the second end of the guide piece;
- and
- an antenna housed within the guide piece and connected to the RF module PCB,
- wherein the antenna is mounted on the RF module PCB for a power feed such that the current distribution though the antenna diminishes toward the terminal end of the antenna as the current flows further way from the power feed point.
