| Abstract: | Using circuit model analysis and full-wave method, an improved H-plane rectangular waveguide T-junction with broadband property is proposed. Based on the principle of cross-coupling and theory of multimode cavity, the coupling matrix is generated by using polynomial synthesis of S-parameter and matrix reduction. Then, a millimeterwave compact waveguide diplexer with dual-mode cross-coupled filters is designed and optimized in this paper. The experimental results reveal that the new diplexer has its advantag... |
