    摘要: A multiband antenna with removed coupling includes a radiator formed as a meander line bent zigzag several times and having a gap filling part in at least one area between neighboring meander lines. The gap filling part interconnects the neighboring meander lines. The multiband antenna further includes a ground connected with the radiator and at least one switch element mounted in an area along the longitudinal direction of the radiator and configured to alternately short or open an area of the radiator. Accordingly, two different resonance frequencies can be tuned using the single antenna, and the antenna efficiency can be enhanced by removing the coupling between the resonant frequencies that are tuned through the gap filling.
