Hi, please provide the necessary steps involved in plotting the group delay vs frequency for an UWB in HFSS,
In order to understand the pulse distortion in UWB antenna transmission, I need it
i know just this way. is it ok for you?
in project manager window, right click results->create modal solution data report -> rectangle plot. category group delay primary sweep frequency.
Thank you for your response. I need to find the group delay in terms of S21.
so i think you should dfine a new variable in hfss and write its equation according to the s_21 phase.
Hello, azita gudarzi... To find the group delay i have taken two identical UWB antennas separated by a distance of 30 cm with face to face orientation. after simulation i did the following steps results->create modal solution data reports-> rectangular plot->group delay-> groupdelay(2,1)-> abs-> new report. is that correct ? or should i use the Matlab to find out the group delay from the standard expression.
You must select group delay with S(1,2) or S(2,1) since we need delay from port 1 to port 2 or vice versa.
