Abstract

The invention relates to a built-in antenna for a wireless communication terminal. The built-in antenna includes at least one first radiator for base station and at least one second radiator for Bluetooth. The built-in antenna also includes a base having the first and second radiators mounted on an outer surface thereof. The base is mounted on a board such that each end of the first and second radiators is electrically connected to the board of a terminal body. The built-in antenna further includes a Bluetooth chip set fixed to the base and electrically connected to the second radiator. The invention efficiently utilizes limited space in a terminal body to miniaturize the product, attaining RF capabilities with high reception sensitivity.

Claims
