antenna.Triangle

Create triangle on xy-plane

Since R2023a

Description

Use the antenna.Triangle object to create a triangular shape in the xy-plane with one vertex at the origin. You can use antenna.Triangle shape to create single-layer or multi-layered antenna using the pcbStack.

Creation

Syntax

tri=antenna.Triangle

tri=antenna.Triangle(PropertyName=Value)

Description

tri=antenna.Triangle creates a triangular shape in the xy-plane with one vertex at the origin.

tri=antenna.Triangle(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, tri = antenna.Triangle(InputType="SSS",Side=0.01) creates a triangle using side-side-side congruence with 10mm side length.

Properties

Name — Name of triangular shape

"myTriangle" (default) | string

Name of the triangular shape, specified as a string.

Example: "TriangleA"

Data Types: string

InputType — Congruency condition

"SSS" (default) | "SAS""ASA"

Congruency condition for the triangle specified as a string. Default condition is "SSS"(side-side-side). Other supported conditions are "SAS"(side-angle-side) and "ASA"(angle-side-angle).

Example: "SAS"

Data Types: string

StartVertex — Start point to draw triangle

[0 0] (default) | 1-by-2 vector

Coordinates of the start point to draw the triangle, specified as a 1-by-2 vector in meter. It is the intersection point between the base side and the left side separated with an angle.

Example: [5 5]

Data Types: double

Side — Side length of triangle

5e-3 (default) | positive scalar | positive 1-by-2 vector | positive 1-by-3 vector

Length of the triangle side, specified as a positive scalar in meter. The default side length is 5 mm and InputType is "SSS". When InputType is

• "SSS", Side accepts a positive 1-by-3 vector for unequal side lengths or a positive scalar for equal side lengths.

• "SAS", Side accepts a positive 1-by-2 vector for unequal side lengths or a positive scalar for equal side lengths.

• "ASA", Side accepts a positive scalar.

Example: 1e-3

Example: [5e-3 10e-3]

Example: [3e-3 4e-3 5e-3]

Data Types: double

Angle — Adjacent side angle

60 (default) | positive scalar | positive 1-by-2 vector

Adjacent side angle of the triangle in degrees, specified as a positive scalar or a positive 1-by-2 vector. This property is activated only when the InputType is either "SAS" or "ASA". It is the angle between the base side and left adjacent side (sides which share the StartVertex) for "SAS" congruence and angle between base side and other two adjacent sides for "ASA" congruence. This property accepts

• A positive scalar value for "SAS" congruence.

• A positive scalar value for equal angles and a positive 1-by-2 vector for unequal angles in "ASA" congruence.

Example: 45

Example: [20 30]

Data Types: double

Examples

Create Right Angled Triangle and Rotate Along Z-Axis

This example shows how to create a triangular shape when two side dimensions and angle between them is known and rotate it by 45-degrees about the z-axis.

Create Triangular Shape

Create a right angled triangular shape with length of one side as 5 mm and the length of other side as 10 mm, and starting vertex [5 5].

Display the created shape.

t = antenna.Triangle(Name="Right_Angled_Triangle",InputType="SAS",...
    Side=[5e-3 10e-3],Angle=90,StartVertex=[5 5]);
show(t)

Rotate Triangle About Z-Axis

Rotate the shape by 45-degrees about the z-axis.

rotateZ(t,45)
