phaseShifter

Create phase shifter in microstrip form

Since R2022b

Description

Use the phaseShifter object to create a phase shifter in the microstrip form. Phase shifters change the phase of a signal using proper matching at the input and output ports and minimum insertion loss.

Creation

Syntax

ps = phaseShifter

ps = phaseShifter(Name=Value)

Description

ps = phaseShifter creates a phase shifter using Teflon as the default substrate.

ps = phaseShifter(Name=Value) sets Properties using one or more name-value arguments. For example, phaseShifter(NumSections=3) creates a phase shifter with 3 U-sections. Properties not specified retain their default values.

Properties

NumSections — Number of U-sections

1 (default) | positive scalar

Number of U-sections, specified as a positive scalar.

Example: ps = phaseShifter(NumSections=3)

Data Types: double

SectionShape — Shape of U-sections

ubendRightAngle (default) | ubendMitered | ubendCurved

Shape of the U-sections, specified as a ubendRightAngle, ubendMitered, or ubendCurved object.

Example: shape = ubendMitered; ps = phaseShifter(SectionShape=shape)

Data Types: double

PortLineLength — Length of port line

0.0200 (default) | positive scalar

Length of the port line in meters, specified as a positive scalar.

Example: ps = phaseShifter(PortLineLength=0.0400)

Data Types: double

PortLineWidth — Width of port line

0.0050 (default) | positive scalar

Width of the port line in meters, specified as a positive scalar.

Example: ps = phaseShifter(PortLineWidth=0.0800)

Data Types: double

Height — Height of phase shifter from ground plane

0.0016 (default) | positive scalar

Height of the phase shifter from the ground plane in meters, specified as a positive scalar. For multilayer dielectrics, use the Height property to create the filter between the two dielectric layers.

Example: ps = phaseShifter(Height=0.0019)

Data Types: double

GroundPlaneWidth — Width of ground plane

0.0300 (default) | positive scalar

Width of the ground plane in meters, specified as a positive scalar.

Example: ps = phaseShifter(GroundPlaneWidth=0.0500)

Data Types: double

Substrate — Type of dielectric material

dielectric object

Type of dielectric material used as a substrate, specified as a dielectric object. The dielectric material in a phaseShifter object with default properties is Teflon.

Example: d = dielectric("FR4"); ps = phaseShifter(Substrate=d)

Data Types: string | char

Conductor — Type of metal used in conducting layers

'PEC' (default) | metal object

Type of metal used in the conducting layers, specified as a metal object. The type of metal in a phaseShifter object with default properties is PEC.

Example: m = metal("Copper"); ps = phaseShifter(Conductor=m)

Data Types: string | char
