Antenna systems providing simultaneously identical main beam radiation characteristics

摘要

Techniques of designing an antenna array or antenna system are described. The antenna system includes a plurality of antenna units structured in a way to form a desired antenna pattern. According to one aspect of the present invention, each of the antenna units includes two antennas disposed orthogonally or in parallel. These antenna units are arranged in a pre-defined geometric pattern to create two substantially similar main beam radiation characteristics for independent polarizations.
