Abstract

This paper presents interesting improvements on evanescent-mode-waveguide bandpass filters reported by the authors at the 1994 IEEE International Microwave Symposium. Those improvements are now successful for newly introducing both the mode-selective negative coupling and the L-angled corner coupling scheme. Experimental results that we took prove the effectiveness of our improvements.<>
