Title:
MULTI-BEAM ANTENNA APPARATUS
Document Type and Number:
WIPO Patent Application WO/1994/013031
Kind Code:
A1
Abstract:
Two equiangular beams are formed by one antenna plane, and a plurality of planes are combined to generate multiple beams. It becomes possible in this way to make the apparatus compact in size and to reduce the wind pressure against the antenna receives. Accordingly, a greater number of antennas can be mounted to one support structure, and the weight of the support structure can be substantially reduced.
