microstripLine
Description
Use the microstripLine
object to create a microstrip transmission
line. A microstrip line is a transmission line that is a basic building block for most RF
planar microwave devices. You can use this transmission line to connect two PCB components or
to create components such as filters, couplers, and feeding elements of various types of
antennas.
Note
This PCB object supports behavioral modeling. For more information, see Behavioral Models. To analyze the behavioral
model for a microstrip transmission line, set the Behavioral
property
in the sparameters
function to true or 1
A few applications of microstrip transmission lines are:
Creating matching feed and coupling networks
Transmitting power from one component to another
Feeding planar antennas and coupling structures
Creating varying inductances or capacitances using open- or short ended- transmission lines
Creation
Syntax
Description
microstrip = microstripLine
creates a default microstrip
transmission line using a Teflon substrate.
microstrip = microstripLine(Name=Value)
sets properties using
one or more name value pair arguments. For example, microstrip =
microstripLine(Length=0.0300)
creates a microstrip line of length 0.0300
meters. Properties not specified retain their default values.
microstrip = microstripLine(
creates a microstrip transmission line from the behavioral model of a txlineobj
)txlineMicrostrip
object in RF Toolbox™.
