Abstract
Provided is an antenna device that is capable of ensuring sufficient antenna performance by maximally utilizing a limited antenna occupied area. The antenna device is provided with a substrate main body (); a ground plane (GND) that is formed on the substrate main body; an antenna-occupied area (AOA) that is provided in contact with one side () of the substrate main body; a slit section (S) that is bored in the ground plane so as to extend from this area in the direction opposite to the one side () of the substrate main body; a power feeding pattern () that is formed so as to extend into the slit section, provided with a power feeding point at the base end side, and connected with a first passive element (P) halfway while the tip end side extends into the antenna-occupied area toward the one side of the substrate main body; an antenna element (AT) of a dielectric antenna that is connected to the tip end of the power feeding pattern and positioned along the one side of the substrate main body; a second passive element (P) that is connected between the antenna element (AT) and the adjoining ground plane; and a ground connection pattern () for connecting the tip end of the power feeding pattern with the ground plane.
