Internal antenna apparatus
First Claim
1. An internal antenna apparatus in a mobile communication terminal including an antenna, a main printed circuit board, and a key pad printed circuit board, the antenna being spaced from the main printed circuit board a predetermined distance, the internal antenna apparatus comprising:
- a feeding pad connected to the antenna;
an antenna feeding part connected between the main printed circuit board and the feeding pad, the antenna feeding part passing through a battery mounting space between the antenna and the main printed circuit board; and
a ground connection part for connecting a ground part of the main printed circuit board to a ground part of the key pad printed circuit board.

Abstract
Disclosed is an internal antenna apparatus. The internal antenna allows feeding and ground connection to an antenna without power loss or degradation of performance in a structure in which a main printed circuit board is separated from the antenna. The internal antenna apparatus in a mobile communication terminal includes an antenna, a main printed circuit board, and a key pad printed circuit board, the antenna being spaced from the main printed circuit board a predetermined distance. A feeding pad is connected to the antenna, an antenna feeding part is connected between the main printed circuit board and the feeding pad, and a ground connection part connects a ground part of the main printed circuit board to a ground part of the key pad printed circuit board. The antenna feeding part includes a coaxial cable and a cable connection part. The antenna feeding part passes through a battery mounting space between the antenna and the main printed circuit board. The cable connection part is connected to the ground of the key pad printed circuit board. Accordingly, it is possible to prevent the degradation of radiation performance of the antenna.
