dgs

Create defected ground structure of PCB element

Since R2023a

Syntax

pcbobject = dgs(rfpcbobject,shape)

Description

pcbobject = dgs(rfpcbobject,shape) creates a defected ground structure (DGS) of the PCB element specified in rfpcb object using the shape object in shape as the DGS structure.

Examples

Dumbbell-Shaped DGS

Create a dumbbell-shaped DGS of a microstrip line.

obj = microstripLine('GroundPlaneWidth',60e-3);
shape = {dumbbell}

shape = 1x1 cell array
    {1x1 dumbbell}

pcb = dgs(obj,shape);

Create DGS Using Square and Circular Dumbbell

Create a DGS of a microstrip line using a square and circular dumbbell.

pcbobj = microstripLine('Length',40e-3,'GroundPlaneWidth',60e-3);
shape = {translate(dumbbell('Type','Circle'),[-10e-3 0 0]),translate(dumbbell,[10e-3 0 0])};
pcb  = dgs(pcbobj,shape);
