pcb2D

2-D cross section of printed circuit board (PCB)

Since R2026a

Description

Use pcb2D to create a 2-D cross section model of a transmission line for use with the 2-D solver.

Creation

Syntax

pcb2d = pcb2D

pcb2d = pcb2D(PropertyName=Value)

S = sparamaters(pcb2d,freq,LineLength=0.5)

Description

pcb2d = pcb2D returns a default 2-D cross section of a microstripline represented by two metal layers with a Teflon substrate in between.

pcb2d = pcb2D(PropertyName=Value) sets Properties of a 2-D cross section of a microstripline using one or more name-value arguments. Properties not specified retain their default values.

S = sparamaters(pcb2d,freq,LineLength=0.5) calculates the s parameters of 2D cross section of microstripline at a specified frequency and line length.

Properties

Name — Cross section name

MyPCB2D (default) | string | character vector

PCB cross section name specified as a string or character vector.

Example: "csname"

Data Types: string

BoardWidth — Cross section width

0.0300 (default) | scalar

Cross section width, specified as a scalar in meters.

Example: 0.0550

Data Types: double

BoardCenter — Cross section center

0 (default) | scalar

X-axis coordinate center of the PCB cross section, specified as a scalar in meters.

Example: 0.0010

Data Types: double

Layers — Metal and dielectric layers

{1x1 trace2D} {1x1 dielectric} {1x1 trace2D} (default) | cell array

Metal and dielectric layers in cross section, specified as a cell array, and ordered from top layer to bottom layer.

Note

If one of the cells includes multiple PCB trace objects, the pcb2d object constructs those traces on the same board layer.

Data Types: cell
