PURPOSE: A radiator for a planer inverted F antenna and an antenna using the same are provided to implement the antenna capable of operating in multiple frequency bands and a small antenna system using the antenna, thereby being applied in various small portable terminal devices for transmitting and receiving signals in a middle frequency band. CONSTITUTION: A planer inverted F antenna(200) includes a ground surface(250), a radiator(240), and an electricity supplying unit(220). The radiator is separated from the ground surface in a predetermined distance. The electricity supplying unit supplies electricity to the radiator. A first slot(245) is formed in the radiator. The first slot is excited by the electricity supply of the electricity supplying unit to the radiator, and currents flow around the first slot. The first slot implements resonant frequency according to the excitation. |
