3 spires? wats that?
this was designed using mimp and later optimized using optimize tool of cst ds to obtain a good match at my frequency. i guess thats ok.
here is the smith chart:
As u can see nothing is going out of the chart. so no problem of active stuff. i will also put a pic of magnitude of s11 (dB) vs freq i obtained for the same freq range here:
so it is not ok? why do you say that it has to be an error? is it not possible that this IS the actual path of variation of impedance wrt frequency and if it is the actual path then could this shape indicate some particular characterisitc of my matching component?
i want to match an impedance to 50 ohm. i simulated a stub matching network using cst and saw the smith chart. At my required frequency there was good match but, the shape of the smith chart (its connecting impedances at various frequency) was like a sharp spike. the tip of the spike is at 50...
