Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/145379
Kind Code:
A1
Abstract:
A plurality of primary radiators (1) are classified by a combination of frequency and polarization of a radiated electric wave, a plurality of primary radiators (1) belonging to the same class are arranged at positions corresponding to vertices of each of triangles in a triangular repetitive pattern TRPattern, and the shape of a main reflector (2) and the shape and placement of the triangular repetitive pattern TRPattern are determined such that the directions of line segments passing through positions corresponding to two vertices of each of the triangles become directions different from the radiation directions of side lobes of electric waves that are radiated from the primary radiators (1) arranged at the positions corresponding to the vertices and thereafter reflected by the main reflector (2).
