摘要

提出了实现宽带波束形成网络(bfn)的两种可能方法。无论耦合水平如何，后向波耦合器的初始物理值都可以保持在固定值。这大大减少了相对较大的阵列掩模布局中的对齐误差。对于共向耦合器，只需要一个0 dB设计就可以获得BFN所需的其余耦合电平。

Wide band beam forming networks for frequency scanned phased arrays

Two possible ways of realizing wideband beamforming networks (BFNs) are presented. Initial physical values for backward-wave couplers can be maintained at fixed values irrespective of the coupling level. This significantly reduces alignment errors in the mask layout of a relatively large array. With codirectional couplers only a single 0 dB design is needed to obtain the rest of the coupling levels required for the BFN.<>
