抄録

This paper proposes a 2mathrm{x}2 array fed by a compact 2-D beamforming network (BFN) in a 5 metals-layer Rogers substrate. The BFN is composed of four interconnected 3mathbf{dB}/90{circ} strip line couplers designed in the broadside coupled stripline structure in the lower (1-4) layers allowing an easy and compact design. The 2mathrm{x}2 patch antenna array designed in the upper (5) layer is connected to the BFN by probes vias generating four beams with unique directions on azimuth and elevation planes. The array inter-element distance is 0. 5lambda_{0}. To validate the performance of the proposed structure, a prototype of a 2mathrm{x}2 patch array has been fabricated and measured. Simulated and measured four beams have been realized. An 8.85dBi highest simulated gain and a 5.97 dBi highest measured gain are realized respectively in (theta=26{circ}, Phi=55{circ}) and (theta=30{circ}, Phi=55{circ} directions when port 1 is excited. The size of the 2mathrm{x}2 array without feeding TML is 0.76 lambda_{0}times 0.81lambda_{0}times 0.04lambda_{0}.
