Abstract
A multi-band built-in antenna of a portable terminal is provided. The antenna includes a first antenna radiator on a front surface of a substrate (e.g., a main board), and a second antenna radiator on an opposite surface of the substrate. The substrate has ground surfaces on both sides separated from a non-ground area on which the radiators are disposed. The first radiator may be in the form of a Planar Inverted F Antenna (PIFA), with a first end branched off into two parts, one part used for power feeding and the other part electrically coupled to the ground surface. The first radiator has a portion that extends from the first end to an opposite end. The second radiator is continuous from the opposite end of the first radiator through a via (hole) in the main board.
