Abstract :
This paper presents the first implementation of Helton´s H∞ approach to wide-band impedance matching. The prototypical problem is to maximize the transducer power gain uniformly over an operating band for a load connected to a generator by a lossless two-port. The H∞ approach computes the maximum transducer power gain attainable by any lossless two-port uniformly over the operating band. This maximum gain is computed for Fano´s classic RLC circuit and an high-frequency antenna represented by measured reflectance data.
