John, the inductive reactance of an ideal shorted stub is a tangent function that increases from zero at zero length up to a maximum on the Smith Chart as the length approaches 1/4WL (undefined at 1/4WL). The equivalent inductance is proportional to the inductive reactance so - very short and it is slightly inductive (low reactance). Longer is more inductive (up to 1/4WL). What you say above seems to be referring to capacitive reactance in open-circuit stubs where very short is highly reactive and longer is less reactive. Yep, you're right. I was only noticing that the length of the line was longer, but that is a shorter stub. My mistake again. |
