bendMitered

Create mitered bend shape on X-Y plane

Description

Use the bendMitered object to create a mitered bend shape on the X-Y plane.

Note

This shape object supports behavioral modeling. For more information, see Behavioral Models.

Creation

Description

example

bend = bendMitered creates a mitered bend shape on the X-Y plane.

example

bend = bendMitered(Name=Value) sets Properties using one or more name-value arguments. For example, bendMitered(ReferencePoint=[1 1]) creates a mitered bend shape with the reference point at [1 1]. Properties not specified retain their default values.

Properties

expand all

Name of the mitered bend shape, specified as a character vector or a string scalar.

Example: bend = bendMitered(Name="bendmitered1")

Data Types: char

Reference point for the mitered bend shape in Cartesian coordinates, specified as a two-element vector.

Example: bend = bendMitered(ReferencePoint=[1 2])

Data Types: double

Example: bend = bendMitered(Length=[0.005 0.005])

Data Types: double

Width of the mitered bend shape in meters, specified as a two-element vector.

Example: bend = bendMitered(Width=[1 1])

Data Types: double

Length of the miter diagonal in meters, specified as a positive scalar.

Example: bend = bendMitered(MiterDiagonal=2)

Data Types: double

Create a mitered bend with default properties.

bend = bendMitered
bend = 
  bendMitered with properties:

              Name: 'myMiteredbend'
    ReferencePoint: [0 0]
            Length: [0.0100 0.0100]
             Width: [0.0050 0.0050]
     MiterDiagonal: 0.0035

View the shape.

show(bend)

Figure contains an axes object. The axes object contains 2 objects of type patch. This object represents PEC.

Create a mitered bend shape of lengths of 10 m and 2 m, width of 2 m, and rotate it about the Z-axis by 60 degrees.

bend = bendMitered(Length=[10 2],Width=[2 2],MiterDiagonal=1);
bend = rotateZ(bend,60)
bend = 
  bendMitered with properties:

              Name: 'myMiteredbend'
    ReferencePoint: [0 0]
            Length: [10 2]
             Width: [2 2]
     MiterDiagonal: 1

show(bend)

Figure contains an axes object. The axes object contains 2 objects of type patch. This object represents PEC.

Mesh the mitered bend shape at a maximum edge length of 1 m.

mesh(bend,MaxEdgeLength=1)

Figure contains an axes object. The axes object contains an object of type patch.

Create mitered bend microstrip.

m = design(microstripLine,6e9,"Z0",75);
layer2d = bendMitered('Length',[m.Length/2 m.Length/2],...
"Width",[m.Width m.Width],'MiterDiagonal',sqrt(2)*m.Width);
robj = pcbComponent(layer2d);
robj.BoardThickness = m.Substrate.Thickness;
robj.Layers{2} = m.Substrate;
show(robj)

Figure contains an axes object. The axes object with title pcbComponent element contains 7 objects of type patch, surface. These objects represent PEC, feed, Teflon.

Compute and plot s-parameters.

freq = (1:2:60)*100e6;
Sckt = sparameters(robj,freq,'Behavioral',true);
Sem = sparameters(robj,freq);
rfplot(Sckt,1,1,'db','-s')
hold on
rfplot(Sem,1,1,'db','-x')

Figure contains an axes object. The axes object contains 2 objects of type line. These objects represent dB(S_{11}).
