Abstract:
A device for improving antenna performance by combining space and angle diversity characteristics, the device comprising:an antenna array board having substantially identical independent first and second antenna elements, wherein the first and second antenna elements include first and second radiation lobes, respectively, and wherein the first and second antenna elements are positioned so that the first and second radiation lobes are directed towards diverse azimuth angles; and substantially identical independent third and fourth antenna elements different from the first and second antenna elements, wherein the third and fourth antenna elements include third and fourth radiation lobes, respectively, and wherein the third and fourth antenna elements are positioned so that the third and fourth radiation lobes are directed towards diverse azimuth angles, wherein the first, second, third, and fourth antenna elements are disposed on a first side of the antenna board so that a line extending perpendicularly from the first side of the antenna array board will intersect no more than one antenna element; and first, second, third, and fourth connectors positioned proximate to the first, second, third, and fourth antenna elements, respectively, for providing an independent signal path for each antenna element.
