<p><P>PROBLEM TO BE SOLVED: To provide an antenna device capable of suppressing the gain reduction in a beam due to an antenna element pattern while easing a structural problem even when the beam is formed at a wide angle. <P>SOLUTION: The antenna device includes a plurality of antenna elements 1<SB>1</SB>to 1<SB>N</SB>arrayed so that the directivity of the antenna element pattern may be turned to a prescribed direction inclined only by a prescribed angle within a range for scanning a beam from a direction vertical to an antenna aperture surface, and a synthesizer 2 for synthesizing a beam on the basis of receiving signals sent from a plurality of antenna elements 1<SB>1</SB>to 1<SB>N</SB>. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
