I have a homework: "Design a 90◦ (Quadrature) hybrid 3dB power divider at the given frequency using microstrip lines. System impedance is 50 Ω. Rogers RO4535 (𝜀𝑟=3.5) with 0.5 mm thickness will be used as the substrate material. Copper will be used as the conductor. Prepare a datasheet. Draw the top/side view (15 pts) and specify all dimensions (15 pts). Include performance plots such as return loss, insertion loss, coupling and isolation (4*10 pts) and comments about the divider (30 pts)." I designed this divider but I cannot find "performance plots such as return loss, insertion loss, coupling and isolation" this things. Could you help me? Thank you.
