Abstract: A portable computer having: a main body; and a monitor in which a planar inverted F antenna (PIFA) is installed. The planar inverted F antenna has: a ground plane; a first radiator connected to the ground plane, spaced from the ground plane; and a second radiator connected to the first radiator, spaced from the first radiator, and with an end connected to an antenna cable. Thus, with only one planar inverted F antenna (PIFA), a multi-band function is performed, and frequency characteristics of a portable computer are improved, since to connect the antenna cable to an end of a planar inverted F antenna enables a frequency band to be broadened, compared with a conventional connection. Also, improvement of an installation structure of the planar inverted F antenna enables assembly and maintenance to be simplified, and manufacturing and repair costs to be reduced.
