Optimize for bandwidth in IE3D

时间:03-24 整理:3721RD 点击:
I'm simulating a patch atenna. It simple to use the optimizer for finding the feeding point for a perfect match at the resonance frequency. But is there a way of also optimizing the antenna for maximum bandwidth? If the antenna height and dielectric is chosen, then the bandwidth is proportional to the width/length ratio. So one needs to maximize the width.

Hi, Jone:

What I would suggest you to do is to define the goal as S(1,1) < -10 dB over a wide frequency range. IE3D should try to optimize the structure for the goal you want.

Best regards,

if you used from probe feed to patch or probe coaxial, so that S(1,1) < -6 can true.
because this probe has further loss.

Actually, the effect of the probe can be accurately modeled in the simulator. You can include the probe and optimize the S(1,1) < -10 dB.
