Abstract :
A new topology for microstrip ultra wide band directional couplers is proposed in this paper. The coupler consists of cascade connection of low-coupled lines or phase shifters (Schiffman lines) and high-coupled sections. The new geometry of Schiffman lines with compensated 180° bend is proposed and verified by electromagnetic simulator.
