MULTI-BAND ANTENNA AND WIRELESS COMMUNICATION DEVICE INCLUDING THE SAME

摘要

There is herein disclosed a multi-band antenna which can adjust respective frequency bands independently. The multi-band antenna comprises a first radiation element having a PIFA structure and a second radiation element having a monopole structure. Also, a second ground terminal is disposed at one end of the first radiation element so as to be connected to a ground plane through a capacitor. The adjustment of the capacitance enables an independent adjustment of a first frequency band. The second radiation element includes a stub so as to allow the second frequency band to be independently adjusted, and a first sub-element and a second sub-element which defines a slit therebetween so as to allow the third frequency band to be independently adjusted. According to the present invention, it is possible to provide a multi-band antenna which can easily adjust respective frequency bands using multi-bands.
