Abstract
A fractional beam forming network antenna includes a beam forming network and a plurality of antennas. The network includes input ports, output ports, and at least one delay device. The beam forming network couples input ports to the output ports through the at least one delay device. The antennas are vertically disposed relative to each other, and coupled to the output ports. At least two of the antennas include a different elevation tilt and/or azimuth rotation relative to each other. A method of fractional beam forming is provided, which includes coupling, using a beam forming network, input ports to output ports through at least one delay device; disposing a plurality of antennas vertically relative to each other; coupling the antennas to the output ports; and rotating at least two of the antennas in different elevation and/or different azimuth relative to each other.
