摘要：Directional coupler is a passive device used for sampling incident and reflected microwave powerconveniently and accurately for various applications in microwave systems. Directional coupler can be realized in strip,micro strip, coax and waveguide lines. Multi section coupled line couplers provide increased bandwidth. Theory ofmulti section coupled line directional couplers in strip line structures is the study for project work and to implement itsdesign in microstrip lines. The operating frequency is 1.8 GHz.
