A low-cost beamformer capable of main beam and null locating is proposed in this paper. This beamformer is suitable for WMNs as the positions of mesh router are fixed. The beamformer consists of 2×2 rectangular array spaced by λ/4 accompanied with a simple beamforming network. With multiplying constant values to output signals from beamforming network, null locating can be accomplished. Firstly, its beamforming capability is tested through computer simulation. Then, a prototype of the beamformer is constructed and tested to confirm its performance in term of signal strength, throughput and delay. Also, the impact of position shift which mesh router is not located on the expected beam direction has also been investigated.
