Abstract
An antenna ground structure of a mobile terminal is disclosed. The antenna ground structure of a mobile terminal is arranged to provide the ground pattern on a Printed Circuit Board (PCB) adjacent to the antenna and to electrically connect the ground pattern to the ground unit of the antenna, so that the area of the ground of the antenna may be expanded to improve Specific Absorption Rate (SAR) and communication performance.
