I have designed a helix antenna. I used antenna design tool kit in HFSS to create the model. to analyze the model I changed the solution type to driven modal but a message appeared:
terminal 'coax_pin_T1': terminals are not used when the solution type is driven modal.
Is my analysis in this...
thanks dear ferdows. but doesn't seem the curve which is attached wrong? (because it has sharp fluctuation.also in most frequencies s11 in 0db means that all the wave reflects!)
thanks
Hi everyone
I designed a circular patch antenna using coax too feed it. I decided to measure its bandwidth using HFSS. so i used driven modal and plot the S11 curve. but the curve is really amazing! (i have attached it)
I have two questions:
1- is driven modal suitable to measure bandwidth...
