WIPO Patent Application WO/2012/073450
Kind Code:
A1
Abstract:
Provided is an antenna device that is capable of assuring sufficient antenna performance by maximally utilizing a limited area occupied by the antenna. The antenna device is provided with a substrate main body (2); 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 (2a) of the substrate main body; a slit section (S) that is created on the ground plane so as to extend from this area in the direction opposite to the one side (2a) of the substrate main body; a feed pattern (3) that is formed so as to extend inside the slit section, provided with a feeding point at the base side, and connected with a first passive element (P1) halfway while the front side is extending into the antenna-occupied area toward the one side of the substrate main body; an antenna element (AT) made of a dielectric antenna that is connected to the front end of the feed pattern and positioned along the one side of the substrate main body; a second passive element (P2) that is connected between the antenna element (AT) and the adjoining ground plane; and a ground connection pattern (5) for connecting the front end of the feed pattern with the ground plane.
