Miniaturised high‐isolation K‐/Ka‐band diplexer with 3D antarafacial channel integration using vertical quasi‐coaxial matching network

IET Microwaves, Antennas &Propagation, Volume 18, Issue 4, Page 291-296, April 2024.
A miniaturised high‐isolation K‐/Ka‐band diplexer with exceeding adjacent channels using 3D antarafacial channel integration and vertical‐quasi‐coaxial‐based matching network is proposed. Working principle, design method and test solution of this proposed K‐/Ka‐band diplexer are well illustrated, and the high‐isolation (>40 dB) in very adjacent ...

Realization of a Wide Stopband Filter Using the Weakest Electric Field Method and Electromagnetic Hybrid Coupling Method

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2024, Issue 1, 2024.
To enhance filter performance in terms of stopband, we propose a wide‐stopband substrate‐integrated waveguide filter based on the rejection of higher‐order modes. The filter establishes the inner and outer coupling windows at the mode’s weakest electric field to achieve mode suppression.
