Built-in type antenna apparatus

An embedded antenna device is provided to easily supply power to the antenna device and connect the antenna device to a ground potential by separating the antenna device from a main PCB. A mobile terminal includes an antenna, a main PCB(Printed Circuit Board), and a keypad PCB. The antenna is apart from the main PCB by a predetermined distance. The antenna includes a feeding pad(140), an antenna feeder(150), and a ground connector. The feeding pad is connected to the antenna. The antenna feeder is connected between the main PCB and the feeding pad. The ground connector couples a ground of the main PCB with a ground of the keypad PCB.
