Transmission Lines
Microstrip lines, coplanar waveguides
Use the transmission line objects and functions to create and visualize different types of transmission lines used on a printed circuit board (PCB).
RF and microwave transmission lines connect different components on a PCB board. They allow signals to flow between the components. There are various types of transmission lines and they all have unique geometries and satisfy different requirements when used on a PCB. A well-designed transmission line reduces the insertion loss in an RF system and improves the circuit performance.
