Create a rectangle with a length of 0.15 m, and a width of 0.15 m.

r  = antenna.Rectangle(Length=0.15,Width=0.15);

Create a second rectangle with a length of 0.05 m, and a width of 0.05 m. Set the center of the second rectangle at half the length of the first rectangle r.

n = antenna.Rectangle(Center=[0.075,0],Length=0.05,Width=0.05);

Create and view a notched rectangle by subtracting n from r.

rn  = r-n;

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