Design  a matching network for microstrip transmission line at 3.25 GHz 

This project involved the theoretical and practical design of an impedance matching network for a microstrip transmission line operating at 3.25 GHz. An open-stub matching technique was used to improve power transfer and minimize signal reflections in RF systems. 

Objectives

• Design an impedance matching network to match a complex load of 100 − j200 Ω to a standard 50 Ω transmission line.

• Reduce signal reflections and improve transmission efficiency at the operating frequency.

• Validate matching performance through simulation.

Outcomes & Contributions

• Achieved effective impedance matching and improved signal transmission at 3.25 GHz.

• Verified that the matching network remained stable and reciprocal.

• Analyzed reflection behavior and confirmed improved matching performance through simulation results.
