microstrip line vs stripline vs suspended stripline vs slotline vs coplanar waveguide vs finline

This page covers comparison between planar transmission lines viz. microstrip line, stripline, suspended stripline, slotline, coplanar waveguide and finline. It compares microstrip line vs stripline vs suspended stripline vs slotline vs coplanar waveguide vs finline and provide difference between them.

Name Characteristic Impedance Radiation Loss Dispersion Component mounting Quality factor
Microstrip Line 20 to 120 Ohm High for low ε and Low for high ε Low Easy for series and difficult for shunt 250
Stripline 35 to 250 Ohm Low None Very difficult because of totally covered structure 400
Suspended Stripline 40 to 150 Ohm Low None Compatible with both shunt and series 500
Slotline 60 to 200 Ohm Moderate High Easy for shunt and difficult for series 100
Coplanar Waveguide 20 to 250 Ohm Moderate Low Easy for both series and shunt 150
Finline 10 to 400 Ohm None Low Compatible with both series and shunt 500
