I am trying to get s-parameters of simple LC-filter located at the micro-strip substrate while sweeping the length of the central strip.
Photo Nr1 shows the circuit: just two ideal L & C components are connected in series with short MLIN and central strip. The length of MLIN is variable (VAR=L).
For single values of the length (for example, L =10mil and L= 90mil) separate results look good (see Photo 2).
But the Sweep results from L = 10 mil to 90mil with two (for example) steps look "dramatic" (are shown together in Photo3).
Could some one explain why it goes wrong?
