I have designed an antenna which is operating in certain range but the solution frequency is beyond that range...If I am changing the solution frequency in to that bandwidth range then the performance is not that much good as that of previous one. Kindly suggest me what to do ? I am using HFSS 14.0
Dear Manzoor Elahi, what is the problem/disadvantage if will set the solution frequency beyound the range of the band width ?
Dear Sounik, as you've mentioned that you're getting better result other than solution frequency. If you increase the frequency, you'll get better radiation pattern as well as you gain will improved. So, you can go beyond of desired bandwidth.
Ofcourse, you would have set your antenna parameters for your desired frequency, so it may cause problem during the time of fabrication, otherwise you can use whatever you're getting.
Hi Sounik
Do not mind but your approach is wrong. EM solver is just for simulation where fabrication is the main thing. Now, by changing the solution frequency your antenna characteristics are changing. However, after validating experimentally your response will be fixed. So, you are on a wrong track.
Next, Mr. J Maree has pointed out the role of solution frequency quite precisely. For HFSS, generally, the solution frequency is equal to (f1+f2)/2 where your sweep is from f1 to f2. Try using this solution frequency and choose your radiation box accordingly as per this frequency, you will find that your measured and simulation results will match perfectly.

Dear Sameer Sir,
Thank you for your response and clear clarification. How ever I would like to inform you that, I do understand the selection of frequency range, actually I took random value just to watch the response of the antenna and when I found this type of result, to clarify my doubts I shared this experience.
Thanking You.
