本文提出了一种用于2 × 2平面贴片阵列天线的新型平面紧凑型二维波束形成网络（BFN），它采用宽边耦合带状线结构。5GHz。二维BFN由四个宽边3dB/900带线耦合器通过短传输线互连而成。所设计和制作的多层Rogers衬底二维BFN在阻抗匹配、传输幅度和相位响应等方面均达到了3.7-6.8GHz的宽带特性。
In this paper, a novel planar and compact 2-D Beamforming Network (BFN) designed in Broadside coupled stripline structure for a 2x2 planar patch array antenna is proposed at 5. 5GHz. The 2-D BFN is composed of four broadside 3dB/900stripline couplers interconnected by short transmission lines. The designed and fabricated 2-D BFN in Multilayer Rogers substrate achieves broadband characteristic over 3.7-6.8GHz frequency band in terms of impedance match, transmission amplitude, and phase responses.
