✦ Synopsis

Abstract

This paper presents a synthesis of simple broadband matching networks consisting of a single line transformer. The procedure uses explicit, measured, or calculated input impedance values and finds characteristic impedance and length of line which match the load to the desired SWR. This kind of matching is especially useful for broadband stacked‐patch configurations, because here microstrip technology provides for arbitrary characteristic impedances of the transformer. The effectiveness of the procedure is demonstrated by examples of two different stacked patch configurations. © 2003 Wiley Periodicals, Inc.

## Abstract The Fourier transform and mode‐matching techniques are applied in the analysis of single‐layered multiconductor transmission lines with finite strip thickness. Based on a quasi‐static approach, the problem is formulated to obtain simultaneous equations for the modal coefficients of the
