摘要：

This letter presents a simple, yet accurate, finite-element frequency domain method of analysis applicable to coaxially driven, axisymmetric microwave structures. The method combines known techniques of modelling coaxially driven, non-radiating structures with those used to model radiating, non-coaxially driven microwave structures. As a result, the method is capable of modelling both types of structures. As an example of the various possible applications of the method, a monopole antenna realized with a ring resonator was analyzed and the results are reported. The results agree very well with the reported measured results for that antenna.
