An iterati¨e method for the design of tapered transmission lines is described. The method applies the Fourier transform to a ( ) linearized Riccati equation to yield a spectral function Q k which relates to a frequency spectrum with a corresponding characteristic impedance profile.

Abstract
The conventional method of designing stepped impedance transmission line networks from gain functions requires the use of a factorization process to obtain a passive input impedance, and then the application of Richards Theorem to determine the element values. A new technique is presented based upon the determination of the Fourier coefficients of the return loss function from which the element values may be obtained immediately for the minimum phase reflection coefficient without any factorization process or synthesis procedure. It is believed that this new technique may be extended directly to the design of mixed lumped‐distributed transmission line networks whereas the conventional approach may not.
