DielectricCatalog

Catalog of dielectric materials

Description

example

dc = DielectricCatalog creates an object handle for the dielectric catalog.

  • To open the dielectric catalog, use open(dc)

  • To know the properties of a dielectric material from the dielectric catalog, use s = find(dc,name).

Examples

collapse all

Open the dielectric catalog.

dc = DielectricCatalog;
open(dc)

Figure Dielectric Materials contains objects of type uimenu, uitoolbar, uitable.

List the properties of the dielectric material Foam.

s = find(dc,'Foam')
s = struct with fields:
                     Name: 'Foam'
    Relative_Permittivity: 1.0300
             Loss_Tangent: 1.5000e-04
                Frequency: 50000000
                 Comments: ''

Use the material Foam as a dielectric in a cavity antenna of height and spacing, 0.0060 m.

d = dielectric('Foam');
c = cavity('Height',0.0060,'Spacing',0.0060,'Substrate',d)
c = 
  cavity with properties:

            Exciter: [1x1 dipole]
          Substrate: [1x1 dielectric]
             Length: 0.2000
              Width: 0.2000
             Height: 0.0060
            Spacing: 0.0060
    EnableProbeFeed: 0
          Conductor: [1x1 metal]
               Tilt: 0
           TiltAxis: [1 0 0]
               Load: [1x1 lumpedElement]

show (c)

Figure Dielectric Materials contains an axes. The axes with title cavity antenna element contains 6 objects of type patch, surface. These objects represent PEC, feed, Foam.

You can add a custom dielectric material to the dielectric catalog. Open the dielectric catalog.

openDielectricCatalog

Figure Dielectric Materials contains objects of type uimenu, uitoolbar, uitable.

To add a new material to the dielectric catalog, click on the row addition icon.

A duplicate record of the dielectric material appears below the selected row.

You can change the record by setting a desired name, permittivity, frequency and thickness of the material to customize.

Create and view the triangular patch microstrip antenna using custom dielectric.

d = dielectric('Mica')
d = 
  dielectric with properties:

           Name: 'Mica'
       EpsilonR: 3
    LossTangent: 1.0000e-04
      Thickness: 0.0060

For more materials see catalog

ant = patchMicrostripTriangular('Substrate',d);
figure;
show(ant)

Figure contains an axes. The axes with title patchMicrostripTriangular antenna element contains 6 objects of type patch, surface. These objects represent PEC, feed, Mica.
