<p>PROBLEM TO BE SOLVED: To provide an antenna device capable of obtaining high isolation and a low correlation coefficient by reducing inter-coupling in a frequency band used by two or more antennas without newly providing a component for reducing the inter-coupling between the antennas, and a portable radio terminal packaging the same therein.SOLUTION: An antenna device comprises: a first antenna; and a second antenna. The first antenna is formed from an opening including: a ground conductor; a notch including an open end; a first feeding point formed in the ground conductor in contact with the open end of the notch; and a first conductor connected over the open end of the notch. The second antenna includes a second feeding point formed in the ground conductor in contact with the notch, and a second conductor of which one terminal is connected to the second feeding point and the other terminal becomes an open end. The second feeding point is formed in a region where an electric field strength caused by the first feeding point is weak, in the ground conductor.</p> |
