摘要： A multiple frequency band antenna is provided that includes a radiating unit having a slot formed on a first surface of the substrate that is closed at one end and open at the other end, and a feed unit formed on a second surface of the substrate to pass through an area on the second surface that corresponds with the same area on first surface between the center and the closed side of the slot. The feeding unit comprises at least one switch which adjusts the size of an area for feeding power to the antenna. The radiating unit is resonated in a plurality of frequency bands when the switch is turned off, and the radiating unit is resonated in a single frequency band which is different from the plurality of frequency bands when the switch is turned on. Consequently, an antenna is implemented for use in multiple frequency bands.
