phase difference of coupler ports

hi
I want draw diagram of phase difference between port 2 and 3 of a 90 degree coupler. but I don't know how to do it. this is the phase of port 2 and 3 in hfss. but I cant show the difference of it

Doesn't the tool support arithmetic expressions for plot variables?

U can export the data to Matlab and Subtract both the phases and Plot it in Matlab..!

Hi,

When you set the plot in HFSS, you write abs(ang_deg(S(1,2)) - ang_deg(S(1,3))) in Y field.
