Shunt Radial Stub - Visualize and Analyze

This example shows you how to create, visualize, and analyze a radial stub shunt on the X-Y plane.

Create a shunt radial stub with default properties.

stub = stubRadialShunt
stub = 
  stubRadialShunt with properties:

             StubType: 'Single'
          OuterRadius: 0.0085
          InnerRadius: 0.0012
                Angle: 90
       PortLineLength: 0.0137
        PortLineWidth: 0.0025
               Height: 8.0000e-04
    GroundPlaneLength: 0.0200
     GroundPlaneWidth: 0.0200
            Substrate: [1x1 dielectric]
            Conductor: [1x1 metal]
           IsShielded: 0

View the stub.


Plot the charge distribution at 5 GHz.

charge(stub, 5e9)

Plot the current distribution at 5 GHz.

current(stub, 5e9)

Calculate and plot the s-parameters.

spar = sparameters(stub,linspace(3e9,5e9,30));
