Coupling coefficient of a new circular eccentric iris for multimodal cavity filters
05 February 2001
In this paper, a new eccentric circular iris is introduces. It is designed to couple two cavities in bandpass filters. The frequency characterization is made by a mode-matching method. Experimental results are in good agreement with theoretical ones. The influence of the aperture radius on the coupling coefficient is also investigated. (C) 2001 John Wiley & Sons, Inc.
