Calculate area of shape in square meters
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.
ans = 0.0212
shape — Shape created using custom elements and shape objects
Shape created using custom elements and shape objects of Antenna Toolbox™, specified as an object.
