Weissfloch transformer for antenna impedance measurements

An antenna impedance measurement technique based on the Weissfloch transformer theorem is described. In this method the antenna impedance is compared to a normalizing load whose value can be determined to a high degree of precision. The method provides a perfect transformer action between the antenna terminals and a point in the input transmission line, with the known transformer ratio. Baluns and other auxiliary antenna components are treated as a discontinuity and their intervening effects in the measurement accuracy are eliminated.
