Performance analysis of a series transformer for complex impedance matching

The ability to match any two complex impedances with a transforming series transmission line of appropriate length is known, but has not been widely studied or deployed. The usefulness of this approach is demonstrated by comparing the performance with that of the series line followed by a quarter-wavelength transformer, single-stub tuner, and double-stub tuner.
