Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2007/119317
Kind Code:
An inexpensive antenna assembly having no mechanical working portion and capable of forming a plurality of beam directions over a wide range. The antenna assembly comprises a plurality of antenna elements (600, 610) each having a feeding portion formed on a dielectric substrate (630), and a reflector (620) having a plurality of reflecting portions opposing the antenna elements (600, 610), respectively. Each of the reflecting portions is parallel with each of the opposing antenna elements (600, 610) and beam direction of each of the antenna elements (600, 610) is differentiated by differentiating the distance between each of the antenna elements (600, 610) and the opposing reflecting portion for the angle of elevation having as reference the plane of the dielectric substrate (630) on which each antenna element (600, 610) is formed.Wide directivity is achieved by combining the beam directions of different angle of elevation of each antenna element (600, 610).
