HFSS 12.1 Antenna Simulating Problem!!

时间:03-31 整理:3721RD 点击:
Hi;

I'm simulated monopol and microstrip antenna in HFSS 11.1. My result is perfect and exactly the same my expectation. However now I have windows 7 (64) and I'm using know HFSS 12.1. Same simulating setup adjustments as HFSS 11.1 are used in HFSS 12.1 and results are very different and poor.

Setup values;

Maximum Delta S = 0.02
Maximum Number of Passes = 15
Minumumm number of passes = 1
Minumum converged Passes = 3.

I think that HFSS 12.1 has a different principle adjustment or any different solution.

If there is a user of HFSS 12.1, he/she can solve my problem.

It's very emergency problem, Please help me!

Thank you.

I do not think that HFSS 12.1 is that different from HFSS v11.1 in terms of results as you have described. I am working with HFSS 12.1. Upload your project files here and i will try to help u!

Here it is. Please check setup. In HFSS 11.1 gain is 3.5dB but in 12.2 it decreases to 0.6dB
Thank you for your interest.

I forgot to correct, please change the Ydik parameter to 3mm or any value which your choise.

[QUOTE=sweetchoto;818384]Have a look at your structure. You are using 'waveport' to excite it and the impeadance of waveport at 140MHz which is your solution frequency is 116ohms. So correct your port impedance first and modify your waveport dimensions in a way to make it 50Ohms. ONly after that you can have a look at your gain.I have done some changes in the setup and added another 'port_verify' setup so that you can correct your waveport impedance.But i do not have time to modify your waveport. Do it yourself. When this issue will be solved, your gain requirement will be fulfilled.
