Remove Holes from Rectangular Shape of Antenna

Open Live Script

Create two rectangle shapes. Change the length and the center of orientation of the second rectangle to the values shown.

rect1 = antenna.Rectangle;
rect2 = antenna.Rectangle;
rect2.Length = 1e-7;
rect2.Width = 0.5

rect2 = 
  Rectangle with properties:

         Name: 'myrectangle'
       Center: [0 0]
       Length: 1.0000e-07
        Width: 0.5000
    NumPoints: 2

Subtract rectangle 1 from rectangle 2

rect3 = rect1-rect2

rect3 = 
  Polygon with properties:

        Name: 'mypolygon'
    Vertices: [9x3 double]

show(rect3)

Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 2 objects of type patch. These objects represent PEC, mypolygon.

Remove holes from the new rectangle.

rect4 = removeHoles(rect3,1e-6)

rect4 = 
  Polygon with properties:

        Name: 'mypolygon'
    Vertices: [4x3 double]

show(rect4)

Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 2 objects of type patch. These objects represent PEC, mypolygon.
