antenna.Polygon

Create polygon on xy-plane

Description

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

Creation

Syntax

polygon = antenna.Polygon

polygon = antenna.Polygon(PropertyName=Value)

Description

polygon = antenna.Polygon creates a polygon shape centered at the origin and on the xy-plane.

polygon = antenna.Polygon(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, pol = antenna.Polygon(Name="polygon-1") creates a polygon with polygon-1 name.

Properties

Name — Name of polygon board shape

"mypolygon" (default) | string

Name of the polygon board shape, specified as a string.

Example: "Polygon1"

Data Types: string

Vertices — Cartesian coordinates of polygon vertices

3-by-3 matrix (default) | N-by-3 matrix

Cartesian coordinates of polygon vertices, specified as a N-by-3 matrix in meters where N is the number of points.

Example: [-1 0 0; -0.5 0.2 0; 0 0 0]

Data Types: double

Examples

Create and Transform Polygon

Create a polygon using antenna.Polygon with vertices at [-1 0 0; -0.5 0.2 0; 0 0 0] and display it.

p = antenna.Polygon(Vertices=[-1 0 0; -0.5 0.2 0; 0 0 0])

p = 
  Polygon with properties:

        Name: 'mypolygon'
    Vertices: [3×3 double]

show(p)
axis equal

Mesh the polygon and display the meshed shape.

mesh(p,0.2)

Move the polygon to a new location on the X-Y plane.

translate(p,[2,1,0])
axis equal
