    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(Name=Value)

    Description

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

    example

    tri=antenna.Triangle(Name=Value) creates a triangle, 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.

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

    Properties

    expand all

    Name of the triangular shape, specified as a string.

    Example: "TriangleA"

    Data Types: string

    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

    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

    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

    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

    This example shows how to create a traingular 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)

    Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 2 objects of type patch. These objects represent PEC, Right_Angled_Triangle.

    Rotate Traingle About Z-Axis

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

    rotateZ(t,45)

    Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 2 objects of type patch. These objects represent PEC, Right_Angled_Triangle.
