Abstract
A high gain built-in antenna for a radio communication terminal with less influence from the human body. This built-in antenna for a radio communication terminal includes bar-shaped second passive elementfacing antenna elements making up dipole antenna. The distance between this second passive elementand the antenna elements making up dipole antennais appropriately set in such a way as to widen the band of the input impedance characteristic by changing mutual impedance between second passive elementand the antenna elements making up dipole antenna
