dielectric

Dielectric material for use as substrate

Syntax

d = dielectric(material)

d = dielectric(Name=Value)

Description

d = dielectric(material) returns dielectric materials for use as a substrate in PCB components.

d = dielectric(Name=Value) returns dielectric materials based on the properties specified by one or more Name,Value pair arguments.

Examples

Create Double Shunt Radial Stub

Create shunt radial stub of type double.

stub = stubRadialShunt(StubType='double');
stub.OuterRadius = [0.0085 0.0065];
stub.InnerRadius = [0.0012 0.0008];
stub.Angle       = [90 60];

View shunt radial stub.

show(stub)

Plot s-parameters.

spar = sparameters(stub,linspace(3e9,5e9,50));
rfplot(spar)

Input Arguments

material — Material from dielectric catalog

'Air' (default) | character

Material from the dielectric catalog, specified as one of the values from the DielectricCatalog.

Example: 'FR4'

Data Types: char

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: Name=Air

Name — Name of dielectric material

character vector

Name of the dielectric material you want to specify in the output, specified as a character vector.

Example: Name='Taconic_TLC'

Data Types: char

EpsilonR — Relative permittivity of dielectric material

1 | real-valued vector

Relative permittivity of the dielectric material, specified as a real-valued vector.

Example: EpsilonR=4.8000

Data Types: double

LossTangent — Loss in dielectric material

0 (default) | real-valued vector

Loss in the dielectric material, specified as a vector.

Example: LossTangent=0.0260

Data Types: double

Thickness — Thickness of dielectric material

0.0060 (default) | positive vector

Thickness of the dielectric material in meters along default z-axis, specified as a positive vector. This property applies only when you call the function with no output arguments.

Example: Thickness=0.05

Data Types: double

Output Arguments

d — Dielectric material

object handle

Dielectric material, returned as an object handle. You can use the dielectric material object handle to add dielectric material as a substrate to any PCB component.
