Abstract
An antenna device includes an antenna elementand a printed circuit boardon which the antenna elementis mounted. The antenna elementincludes a basewhich is made of a dielectric material and a radiation conductor formed on at least one surface of the base. The printed circuit boardincludes ground clearance regionhaving substantially a rectangular shape and having one side contacting an edge of the printed circuit board and other three sides surrounded by an edge line of a ground pattern, an antenna mounting regionprovided within the ground clearance region, and at least one frequency adjusting elementprovided within the ground clearance region. The frequency adjusting elementis provided on the far side of the antenna mounting regionas viewed from an edgeof the printed circuit board
