Abstract :
A low cost beamformer capable of main beam and null steering is proposed in this paper. This beamformer is suitable for WMNs as positions of mesh router are fixed. The beamformer consists of 2×2 rectangular array spaced by λ/4 accompanied with a simple beamforming network presented from the previous work. With multiplying constant values to output signals from beamforming network, null steering can be accomplished. Its beamforming capability is tested through computer simulation.
