ANTENNA APPARATUS AND MOBILE TERMINAL HAVING THE SAME

摘要

According to an embodiment of the present invention, a mobile terminal comprises a conductive member for resonating in first and second frequency band; a power supply part for supplying power to the conductive member; a changing part between the power supply part and the conductive member to change the center frequency of the first frequency band by changing a capacitance value using one or more variable capacitors; and cut-off part having one or more lumped constant elements for reducing influences on the second frequency band caused by the change of the capacitance when the center frequency of the first frequency band is being changed.
