plotRefl

plotRefl(port, varargin)

Full definition:

h = plotRefl(port,varargin)

plot the reflection coefficient of a port into a Smith chart. left and right facing triangles mark the lower and upper cutoff frequency of the pass bands. An asterisk marks the frequnecy with the lowest reflection.

input:

port: port data structure. Call calcPort with an appropriate frequency vector before calling this routine

output: graphics handle for further modification of the plot.

variable input:

‘precision’: number of decimal places (floating point precision) for the frequency (always in MHz), default is 0
‘threshold’: Threshold value (in dB) for the upper and lower cutoff frequency, default is -3
‘fmarkers’: set lower and upper frequency marker in Hz manually, like so: [4e9, 6.5e9]

example:

myport = calcPort(myport, Sim_Path, linspace(f_0-f_c, f_0+f_c, 200));
plotRefl(myport, 'fmarkers', [4e9, 6.5e9]);
