Design symmetric strip transmission line around given frequency

Description

sline = design(slineobj,frequency) designs an strip transmission line around the specified frequency with default 50 ohm reference impedance and 0.25 line length.

example

sline = design(___,Name,Value) designs a strip transmission line with additional options specified by name-value pair arguments.

Note

PCB components designed using the design function resonates around the specified frequency with a 10 to 15% tolerance.

Examples

collapse all

Design a strip transmission line around 3 GHz and with a characteristic impedance of 75 ohms.

sline = design(stripLine, 3e9,'Z0',75);
figure;
show(sline); 

Plot the s-parameters of this transmission line.

spar = sparameters(sline,3e9);
rfplot(spar)

Input Arguments

collapse all

Strip transmission line, specified as a stripLine object.

Example: sline = stripLine; design(sline,2e9) designs a microstrip transmission line around a frequency of 2 GHz.

Resonant frequency of the transmission line, specified as a real positive scalar.

Example: 55e6

Data Types: double

Name-Value Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'Z0',2

Characteristic impedance of the line in ohms, specified as the comma-separated pair consisting of 'Z0' and a positive scalar.

Data Types: double

Length of the in terms of Lambda, specified as the comma-separated pair consisting of 'LineLength' and a positive scalar.

Data Types: double

Output Arguments

collapse all

Strip transmission line operating around the specified reference frequency, returned as a stripLine object.
