Generalized non-uniform transmission-line models for local radiation from microstrip bends in MMICs

摘要

Although microstrip bends in high-speed digital MMICs have been widely investigated for the past two decades, their local radiation characteristics rather than their reflection characteristics have not been completely explored yet. In this paper, the generalized non-uniform transmission-line equations are used in analysing the microstrip bends including their local radiations. In our new models, the whole structure of a bend is regarded as a non-uniform transmission line that is totally governed by the generalized non-uniform transmission-line equations. Except for analytical simplification and broad bandwidth performance, the new analysis could indicate where the strongly local radiations along a bend structure come from.
