Abstract
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.<>
