A Graphical Method for Computing Short Impedance Matching Transformers

Abstract

This report describes a simple method for computing the dimensions of a sleeve impedance transformer for a coaxial line feeding antenna. Other means of making this calculation are well known, but the method described here possesses two distinct advantages. In the first place, the actual distance between the radiating element and the generator end of the transformer is reduced to an absolute minimum, thus lowering the frequency sensitivity of the system. In the second place, the computation is very rapid, being a simple graphical process.
