Examples

Create Notched Rectangle

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;
show(rn)

Calculate the area of the notched rectangle.

area(rn)

ans = 0.0212
