In this paper, the Computer Aided Design of a new rectangular waveguide filter structure is proposed for achieving the dual-mode operation. It preserves the longitudinal inline topology used in the classical circular waveguide configuration, which can provide quasi-elliptic function responses. However, it has no coupling or tuning screws and it is exclusively made up of sections of aligned rectangular waveguides. This leads to a very efficient full-wave analysis based on the Mode-Matching method. The proposed CAD is illustrated with a four order prototype, whose results are compared with other numerical technique.}, keywords = {Dual-Mode cavities, elliptic filter response, rectangular waveguide filter}, issn = {0149-645X}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=4632911\&isnumber=4632906}, author = {J A Ruiz-Cruz and Zhang, Y and Montejo-Garai, J R and Rebollar, J M and Zaki, K A} }
