Abstract:
A broad band patch antenna array comprising:a plurality of generally rectangular patch antennas, each of the patch antennas having a first side and a second side longer than the first side;the patch antennas being arranged in a first column wherein the first sides of the patch antennas are in generally co-planar relation to one another, and a second column wherein the second sides of the patch antennas are aligned in generally opposed, parallel relation to the first sides of the patch antennas of the first column such that the patch antennas of the second column are orthogonal to the patch antennas of the first column; anda plurality of antenna feed conductors each having an equal length, each of the antenna feed conductors being electrically connected to a respective one of the patch antennas within a given column at a corresponding location;wherein the equal length of the antenna feed conductors and the orthogonal orientation of the patch antennas of the second column to the patch antennas of the first column facilitate the reception and transmission of electromagnetic radiation in two planes.
