The analysis of E-plane filters with loaded resonators with mode matching method

Abstract

This paper presents the analysis of an E-plane filter with loaded resonators. Using these structures, not only solves the problem of excessive length of conventional E-plane filters, but also leads to a great improvement in rejection of upper stop band. This method has a high accuracy in wide frequency range. In order to demonstrate the validity of this method, the results of construction and simulation are compared; and this comparison has a good compatibility.
