phaseShifter

Create phase shifter in microstrip form

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

Description

example

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

example

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

expand all

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

Example: ps = phaseShifter(NumSections=3)

Data Types: double

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

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

Data Types: double

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

Example: ps = phaseShifter(PortLineLength=0.0400)

Data Types: double

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

Example: ps = phaseShifter(PortLineWidth=0.0800)

Data Types: double

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

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

Example: ps = phaseShifter(GroundPlaneWidth=0.0500)

Data Types: double

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

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

Figure contains an axes object. The axes object with title phaseShifter element contains 6 objects of type patch, surface. These objects represent PEC, feed, Teflon.

Create a phase shifter at the interface of a multilayered dielectric.

ps = phaseShifter;
ps.Substrate = dielectric(Name={'Teflon','Teflon'},EpsilonR=[2.1 2.1], ...
    LossTangent=[0 0],Thickness=[0.8e-3 0.8e-3]);
ps.Height = 0.8e-3;

Visualize the phase shifter.
