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 element392facing antenna elements making up dipole antenna321. The distance between this second passive element392and the antenna elements making up dipole antenna321is appropriately set in such a way as to widen the band of the input impedance characteristic by changing mutual impedance between second passive element392and the antenna elements making up dipole antenna321.
