Slot line filters and couplers

Power dividers and directional couplers - Wikipedia The main line is the section between ports 1 and 2 and the coupled line is the section between ports 3 and 4. Since the directional coupler is a linear device, the notations on figure 1 are arbitrary. (PDF) Slot-Line Resonator Filters - ResearchGate
