This article proposes the lattice network as a beneficial alternative to T‐ and $ \Pi - $ topologies for modeling symmetric transmission line discontinuities and components.The lattice network presents some important features, which make it a powerful tool to find realizable equivalent circuits. The limitations of the T‐ and $ \Pi - $ topologies and the validity of the lattice network in terms of realizability are highlighted in this article through two microstrip components: a dumbbell‐shaped defected ground structure and a microstrip stepped‐impedance hairpin resonator. Moreover, the lattice image impedance is proposed here as a parameter that allows determining whether a branch of the network is predominant . © 2012 Wiley Periodicals, Inc.
