Microstrip Transmission Lines Impedance formula
The formula for calculating the characteristic impedance (Z0) of transmission lines depends on the specific configuration and type of transmission line. Here are some common formulas for calculating Z0:
1. Coaxial Cable:
![\[Z_0 = \frac{60}{\sqrt{\epsilon_r}} \log\left(\frac{D}{d}\right)\]](https://x-calculator.com/wp-content/ql-cache/quicklatex.com-acf0f423a06fe3cff96e152586039256_l3.png "Rendered by QuickLaTeX.com")
Where:
– Z0 is the characteristic impedance of the coaxial cable.
– εr is the relative permittivity of the dielectric material.
– D is the outer diameter of the outer conductor.
– d is the inner diameter of the inner conductor.
2. Microstrip Transmission Line:
![\[Z_0 = \frac{87}{\sqrt{\epsilon_r + 1.41}} \log\left(\frac{5.98h}{0.8w + t}\right)\]](https://x-calculator.com/wp-content/ql-cache/quicklatex.com-6aa5619816d2a55b262a938fe289ab10_l3.png "Rendered by QuickLaTeX.com")
Where:
– Z0 is the characteristic impedance of the microstrip transmission line.
– εr is the relative permittivity of the substrate material.
– h is the height of the substrate.
– w is the width of the trace.
– t is the thickness of the substrate.
3. Stripline Transmission Line:
![\[Z_0 = \frac{60}{\sqrt{\epsilon_r}} \log\left(\frac{W}{T} + \frac{1}{\pi}\left(1 - \frac{1}{2}\frac{T}{W}\right)\right)\]](https://x-calculator.com/wp-content/ql-cache/quicklatex.com-e7ab4402dfd2e902ed9c91446d159fb1_l3.png "Rendered by QuickLaTeX.com")
Where:
– Z0 is the characteristic impedance of the stripline transmission line.
– εr is the relative permittivity of the substrate material.
– W is the width of the trace.
– T is the thickness of the substrate.
Please note that these formulas are simplified versions and may not account for all factors and variations. It’s recommended to use specialized tools or software for accurate and comprehensive transmission line impedance calculations.
