positive return loss
Hi,
I have modeled a partch antenna (including the feed structure). But the problem is when I plot the Return Loss (dB) over the frequency range there is a section where the return loss is > 0 db and reaches a peak of 6dB.
Thats doesn't make sence to me. It's a passive structure.
Just wanted to check if that make sence in any way.
thanks
