<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive antenna assembly, capable of forming a plurality of beam directions over a wide range, without mechanical operating parts. <P>SOLUTION: The antenna assembly is provided with a plurality of antenna elements 600 and 610, formed on a dielectric substrate 630 and respectively having power feeding parts and a reflector 620, having a plurality of reflecting parts facing the respective antenna elements 600 and 610. The respective reflecting parts are mutually parallel to the respective facing antenna elements 600 and 610, and beam directions of the respective antenna elements 600 and 610 are mutually different, by making distances to the reflecting parts facing the respective antenna elements 600 and 610 different in each of the antenna elements 600 and 610, with respect to the angle of elevation for making the surface of the dielectric substrate 630 with the respective antenna elements 600 and 610 formed thereon as reference. Wide directivity is realized, by combining beam directions of the respective antenna elements 600 and 610 with the different angles of elevation. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
