rlgc

Compute resistances, inductances, conductances, and capacitances

Since R2022b

Syntax

rlgcparams = rlgc(txline,frequency)

Description

rlgcparams = rlgc(txline,frequency) returns the resistances, inductances (L), conductances (G), and capacitances per unit length of a transmission line at the specified frequency.

Examples

RLGC of Microstrip Transmission Line

Create a microstrip transmission line using a copper conductor.

txline = microstripLine;
txline.Conductor.Name = 'Copper';
txline.Conductor.Conductivity = 5.8e7;
txline.Conductor.Thickness = 0.001;

Calculate the RLGC values of microstrip transmission line at 1 GHz.

freq = 1e9;
RLGCparams = rlgc(txline,freq)

RLGCparams = struct with fields:
    R: 1.4649
    L: 2.0565e-07
    G: 9.6413e-05
    C: 9.5171e-11

Input Arguments

txline — Transmission line

transmission line object

Transmission line, specified as a coupledMicrostripLine, microstripLine, or microstripLineCustom object.

Example: txline = microstripLine;rlgc(txline) calculates the RLGC values of the microstrip transmission line object with handle txline.

Data Types: char | string

frequency — Frequency to calculate RLGC values

scalar

Frequency to calculate the RLGC values, specified as an integer in Hz.

Output Arguments

rlgcparams — RLGC values of transmission line

structure

RLGC values line per unit length of the transmission line, returned as a structure with field names for the R, L, G, and C values. Each field contains an n-by-n double precision matrix where n is the total number of traces in the transmission line object. Diagonal and nondiagonal entries in the matrix are self and coupled elements in the traces, respectively.
