✦ Synopsis

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. Numerical results show that the spectral function and the calculated spectrum impro¨e with iterations. The method also remo¨es discontinuities in impedance profiles, and can be applied to design impedance-matching circuits and microwa¨e filters with arbitrary passband characteristics.

## Abstract Impedance matching of a loaded microstrip transmission line is performed by using only parasitic elements. By the term “parasitic” matching element we mean that there is no physical connection between the conductors of the matching subsystem and the conductors of the main circuit. We co
