Abstract

In this paper, a rigorous analysis for a microstrip cross is presented by using 2D generalized transmission‐line equations. The 2D generalized transmission‐line equation is developed from the 1D generalized transmission‐line equation in [1], which was derived from circuit theory, while the equation coefficients are determined from full‐wave numerical solutions. Although 1D generalized transmission‐line equation can well model many microstrip structures, such as discontinuities and low‐pass filters, it is confined to be used for those structures which can be regarded as 1D finite‐length nonuniform transmission‐line. For a microstrip cross, the novel 2D generalized transmission‐line equation whose coefficients are determined by dynamic numerical methods can have broadband frequency characteristics. For the investigated microstrip cross, the S parameters for a frequency band from 4 GHz to 24 GHz can be calculated by using only one group of the 2D generalized equation at frequency of 14 GHz. © 2002 Wiley Periodicals, Inc.
