ABSTRACT:
A multi-band antenna and a notebook computer with a built-in multi-band antenna are disclosed. Since the multi-band antenna is installed at the inner side of a upper and a lower case, it is much favored for a radio communication when a computer is in use by standing up a display device. The multi-band antenna includes at least two transmitting and receiving parts formed with different lengths to fit frequency bands, so that a remote communication of at least two or more bands can be made. The multi-band antenna is positioned between liquid crystal and a side wall of the lower case, and a grounding unit is installed to contact a liquid crystal frame. That is, since the grounding unit is grounded to the liquid crystal frame and the bracket, substantially, the liquid crystal frame and the bracket are wholly grounded to ensure a stable radio frequency communication.
