Single-stub matching is a very common method for impedance matching using microstrip lines at frequences in the UHF band (300-3000 MHz) and above. In Figure (PageIndex{1}), the top (visible) traces comprise one conductor, whereas the ground plane (underneath, so not visible) comprises the other conductor.

Consider a capacitor with a negative capacitance value, controlled by the equation ( V(t)=left(frac{-1}{C}right)int I(t); dt ), where the negative sign represents an intrinsic property that causes the current flowing through the capacitor to flow in the reverse direction (compared to current flowing through a nonnegative capacitor) or ...
Understanding Matching Networks | Selected Topics
Thus, matching networks use capacitors and inductors, and not resistors. It is difficult to design a wideband matching network. This is not surprising when we remember that the matching network is composed of reactive components: the impedance of inductors and capacitors is dependent on frequency; thus, changing the frequency of the signals ...

I have seen impedance matching, but usually they are matching a non reactive source impedance, e.g. 50 Ω, to some complex load. In this case the source has a purely complex impedance of -10j Ω and I want to match this to 50 Ω by using some transformer method (single stub, 1/4 wave, or combination, or whatever).

Antenna Impedance Matching – Simplified
impedance match by bringing impedance to the center of the chart, which corresponds to a pure resistance of 50 Ω by adjusting the reactance values. This is achieved by designing a matching network, which is a circuit between the feed line and the antenna. A Smith chart can be used to determine matching network''s lumped element values.
