A compact and wideband 4x4 BM based four directions beamforming antenna is proposed and designed in 3-layers substrate. A broadside coupled stripline structure is used in the lower layers to design a high performance 3dB/900 coupler as the basic element of the BM. A compact size, wideband and low loss 4x4BM is realized at mmWave frequencies. The upper layer is used to design the antenna array. The simulated return loss at all ports is below-10dB. The simulated four directional beams 12.50, -380, 370, -130 and the second lobe levels -12, -10, -10.5, -12.2dB are respectively achieved when ports 1,2,3, and 4 are excited. The beamforming system exhibits an average gain of 9.6dBi. The measurement of the beamforming antenna module confirms the simulation results.
