Create and view a default circle.

circle1 = antenna.Circle;

Create a circle with a radius of 1 m. The center of the circle is at [1 0].

circle2 = antenna.Circle('Center',[1 0],'Radius',1);

Add the two circles.

add(circle1,circle2)

Create circle with a radius of 1 m. The center of the circle is at [1 0].

circle1 = antenna.Circle('Center',[1 0],'Radius',1);

Create a rectangle with a length of 2 m and a width of 4 m centered at the origin.

rect1 = antenna.Rectangle('Length',2,'Width',2);

Add the two shapes together using the + function.

polygon1 = circle1+rect1

polygon1 = 
  Polygon with properties:

        Name: 'mypolygon'
    Vertices: [21x3 double]

show(polygon1)
