![]() It can be connected in two ways (OC & SC) 1. Stub Matching : For high microwave frequencies, a section of a transmission line can be used as matching network at suitable distances. ![]() Impedance matching using short circuit stubs. Impedance matching using half wave lines. Impedance matching using quarter wave transformer. Impedance matching using L- C of a transmission line. Impedance matching using L or C of a transmission line. Different types of impedance matching : Reflection less match Conjugate match Zo matchĤ Reflection less match Conjugate match Zo match In order to avoid the problems we need a Matching Network. Signal get reduced due to reduction of signal-to-noise ratio. Frequency stability problem in generator. All the above will be affected due to mismatch problems.ģ Effects of Mismatch : Power loss in feeder line. Presentation on theme: "IMPEDANCE MATCHING & SMITH CHART"- Presentation transcript:Ģ Impedance Matching of RF Transmission Lines :īasic requirements needed for a better transmission line High transmission efficiency Very small VSWR Can able to operate over a range of frequencies.
