antenna.Rectangle

Create rectangle centered at origin on xy-plane

Description

Use the antenna.Rectangle object to create a rectangle centered at the origin and on the xy-plane. You can use antenna.Rectangle to create single-layer or multi-layered antennas using pcbStack.

Creation

Syntax

rect = antenna.Rectangle

rect = antenna.Rectangle(PropertyName=Value)

Description

rect = antenna.Rectangle creates a rectangle centered at the origin and on the xy-plane.

rect = antenna.Rectangle(PropertyName=Value) sets properties using one or more name–value arguments. PropertyName is the property name and Value is the corresponding value. You can specify several name-value arguments in any order as PropertyName1=Value1,...,PropertyNameN=ValueN. Properties that you do not specify, retain their default values.

For example, rec = antenna.Rectangle(Length=2) creates a rectangle with a 2 m length.

Examples

Create Rectangle with Default Properties

Create a rectangle shape using antenna.Rectangle and view it.

r1 = antenna.Rectangle

r1 = 
  Rectangle with properties:

         Name: 'myrectangle'
       Center: [0 0]
       Length: 1
        Width: 2
    NumPoints: 2

show(r1)

Create and Rotate Rectangle Using Specified Properties

Create and view a rectangle with a length of 2 m and a width of 4 m.

r2 = antenna.Rectangle(Length=2,Width=4);
show(r2)
axis equal

Rotate the rectangle.

rotateZ(r2,45);

show(r2)

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
