This is a type of
Transmission Media. It is one of the reliable methods for creating a transmission line. It is a transverse electromagnetic (TEM) transmission line. This was invented by Robert M. Barrett.
In case of calculating the values then you can consider the following parameters. A stripline is a W unit wide and T units thick strip of conducting material surrounded by dielectric material above and dielectric material below. This is primarily used in PCB design and routing to connect one component to another.
T=Thickness W=Width Er=Relative Permittivity H=Distance between Ground Planes
Properties of Stripline :
- A flat strip of metal sandwiched between two ground planes.
- The insulating material of the substrate forms a dielectric usually made from a Fire Retardant material called FR7.
- It is non-dispersive.
- Does not have a cut-off frequency.
- Good against Electromagnetic Induction.
- Slower propagation speed compared to Microstrip.
- Can also support higher order TM and TE modes but this is usually avoided.
- Attenuation due to dielectric loss is of the same form as that of any TEM lines.
- Fields of TEM mode on a stripline must satisfy Laplace’s Equation.
