antenna.Polygon

Create polygon on X-Y plane

Description

Use the antenna.Polygon object to create a polygonal board shape 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

polygon = antenna.Polygon

polygon = antenna.Polygon(Name=Value)

Description

polygon = antenna.Polygon creates a polygonal board shape centered at the origin and on the X-Y plane.

polygon = antenna.Polygon(Name=Value) sets properties using 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 not specified retain their default values.

Properties

Name — Name of polygon board shape

"mypolygon" (default) | string | character vector

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

Example: "Polygon1"

Data Types: char | 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 with each element measured in meters, N being 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: [3x3 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
