Currently i'm working in Microstrip patch antenna, How can i simulate Reflection coefficient (S11) in HFSS simulation tool...
Is it simulate reflection coefficient or generating reflection coefficient graph.
If it is generating reflection coefficient graph then your structure must be simulated without any errors......
Then after
Goto Results->right click->Create modal solution data report->rectangular plot-> select S(1,1)) in dB.......
To do it, after modeling your antenna you should create an air box with a base of the same size and a height at least 10 times the height of your circuit. Then, select the face of the air box in which your feed via is placed and set it as "Wave Port" by right click on it-> Assign Excitation-> Wave Port. After that, select the 5 remaining faces and set them as "Radiation" by right click on them-> Assign Boundary-> Radiation.
Finally, run your simulation (it is important that you use a frequency sweep) and once it is finished follow the steps Anvesh Kumar Nella told you.
Cheers!
hello Dear Subramani,
