The application of moment methods to the broadband analysis of radiating planar circuits

Abstract

The use of moment method techniques for broadband analysis of radiating planar circuits is considered. First, the various approaches to the application of moment method techniques to the analysis of planar transmission line structures are reviewed. Difficulties encountered in extending these techniques over large bandwidths are then discussed. Finally, a method for obtaining accurate broadband data via a combination of moment methods and quasi-static analysis is presented and applied to an example of a radiating planar circuit structure.<>
