Beam forming network for a multibeam antenna

摘要

A beam forming network comprising multi-deck circuitry with a plurality of levels within each deck formed by asymmetric striplines having a multiplicity of inner conductor levels. Interlevel coupling is accomplished with 3 dB couplers which power split signals incident thereto between transmission line levels and 0 dB interlevel couplers which transfer signals from one level to another without significant attenuation.
