getZ0

Calculate characteristic impedance of transmission line

Description

example

z0 = getZ0(txline) calculates the characteristic impedance z0 of a transmission line.

z0 = getZ0(txline,freq) calculates the characteristic impedance at the specified frequency.

Examples

collapse all

Create a microstrip transmission line with default properties.

mline = microstripLine
mline = 
  microstripLine with properties:

              Length: 0.0200
               Width: 0.0050
              Height: 0.0016
    GroundPlaneWidth: 0.0300
           Substrate: [1x1 dielectric]
           Conductor: [1x1 metal]

Calculate the characteristic impedance of the line.

Z0 = getZ0(mline)
Z0 = 49.6897 - 0.0003i

Input Arguments

collapse all

Transmission line, specified as one of the following: coplanarWaveguide, coupledMicrostripLine, and microstripLine.

Example: txline = microstripLine;getZ0(txline). Calculates the characteristic impedance of the microstrip transmission line object with handle txline.

Data Types: char | string

Frequency to calculate the characteristic impedance, specified as a positive scalar in hertz.

Output Arguments
