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

example

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

example

rect = antenna.Rectangle(Name,Value) sets properties using one or more name-value pair. For example, rectangle = antenna.Rectangle('Length',0.2) creates a rectangle of length 0.2 m. Enclose each property name in quotes.

Properties

Name of rectangle, specified a character vector.

Example: 'Name','Rect1'

Example: rectangle.Name = 'Rect1'

Data Types: char | string

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

Example: 'Center',[0.006 0.006]

Example: rectangle.Center = [0.006 0.006]

Data Types: double

Rectangle length, specified a scalar in meters.

Example: 'Length',2

Example: rectangle.Length = 2

Data Types: double

Rectangle width, specified a scalar in meters.

Example: 'Width',4

Example: rectangle.Width = 4

Data Types: double

Number of discretization points per side, specified a scalar.

Example: 'NumPoints',16

Example: rectangle.NumPoints = 16

Data Types: double

Open Live Script

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)

Figure contains an axes object. The axes object contains 2 objects of type patch. This object represents PEC.

Open Script

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)

Open Live Script

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)

Figure contains an axes object. The axes object contains 2 objects of type patch. This object represents PEC.

Calculate the area of the notched rectangle.

area(rn)
ans = 0.0212
