antenna.Circle

Create circle centered at origin on xy-plane

Description

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

Creation

Syntax

circle = antenna.Circle

circle = antenna.Circle(Name=Value)

Description

circle = antenna.Circle creates a circle centered at the origin and on the xy-plane.

circle = antenna.Circle(Name=Value) creates a circle, with additional Properties specified by one or more name-value arguments. 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 that you do not specify retain their default values.

Properties

Name — Name of circle

"mycircle" (default) | string

Name of circle, specified as a string.

Example: "Circle1"

Data Types: string

Center — Cartesian coordinates of circle center

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

Cartesian coordinates of circle center, specified as a 2-element vector in meters.

Example: [0.006 0.006]

Data Types: double

Radius — Circle radius

1 (default) | scalar

Circle radius, specified as a scalar in meters.

Example: 2

Data Types: double

NumPoints — Number of discretization points on circumference

30 (default) | scalar

Number of discretization points on circumference, specified as a scalar.

Example: 16

Data Types: double

Examples

Create Circle with Default Properties

Create and view circle using antenna.Circle and view it.

c1 = antenna.Circle

c1 = 
  Circle with properties:

         Name: 'mycircle'
       Center: [0 0]
       Radius: 1
    NumPoints: 30

show(c1)

Create Circle with Specified Properties

Create a circle centered at the origin with a radius of 4 m.

c2 = antenna.Circle(Radius=4)

c2 = 
  Circle with properties:

         Name: 'mycircle'
       Center: [0 0]
       Radius: 4
    NumPoints: 30

Add Two Shapes

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

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

Create a rectangle with a length of 2m and a width of 4m 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)
