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
2- as i have understood we should use -10 db point to measure bandwidth. in fact the band between -10 db points is the bandwidth. am i right?
Thanks for helping me
