Coupler - an overview | ScienceDirect Topics

End coupled (used in filters but not used in couplers) In order to make a quadrature coupled-line coupler you need to couple a quarter-wave section; end-coupled structures are not useful in this case. That leaves two broad categories of coupled line couplers, edge coupled, and broadside coupled (and perhaps some gray territory in between!)
