Re: Optimization in IE3D
Hi, Micro-tech:
Again, depending upon whether the antenna is narrow bandiwdth or wide bandwidth, you may consider the following:
1. For narrow bandwidth:
Re[S(1,1)] = 0 and Im[S(1,1)] = 0 at the resoannt frequency. If you have multiple resonant frequencies, you just define the goals at those multiple frequencies. If you can achieve Re[S(1,1)] = 0 and Im[S(1,1)] = 0 at a specified frequency, you are getting the best for RL.
2. For wider bandwidth:
You specify dB[S(1,1)] < -10 dB for a frequency range. If you have multiple bandwidths, you specify the goal dB[S(1,1)] < - 10 dB multiple times with each one for a bandwidth.
Best regards,
