antenna.Rectangle

Create rectangle centered at origin on X-Y plane

Description

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

Creation

Syntax

rect = antenna.Rectangle

rect = antenna.Rectangle(Name=Value)

Description

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

rect = antenna.Rectangle(Name=Value) sets properties using one or more name-value pair. Name is the property name and Value is the corresponding value. You can specify several name-value arguments in any order as Name1= Value1, ..., NameN=ValueN. Properties not specified retain their default values.

Properties

Name — Name of rectangle

"myrectangle" (default) | string | character vector

Name of rectangle, specified as a string or a character vector.

Example: "Rect1"

Center — Cartesian coordinates of center of rectangle

[0 0] (default) | 2-element vector

Cartesian coordinates of center of rectangle, specified as a 2-element vector with each element measured in meters.

Example: [0.006 0.006]

Data Types: double

Length — Rectangle length

1 (default) | scalar

Rectangle length, specified as a scalar in meters.

Example: 2

Data Types: double

Width — Rectangle width

2 (default) | scalar

Rectangle width, specified as a scalar in meters.

Example: 4

Data Types: double

NumPoints — Number of discretization points per side

2 (default) | scalar

Number of discretization points per side, specified as a scalar.

Example: 16

Data Types: double

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
