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 contains 2 objects of type patch. This object represents PEC.

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 contains 2 objects of type patch. This object represents PEC.
