Wideband Modeling of arbitrarily shaped E-plane waveguide components by the "boundary integral-Resonant Mode expansion method"
IEEE Transactions on Microwave Theory and Techniques, 1996Co-Authors: P. Arcioni, M. Bressan, G. Conciauro, L. PerregriniAbstract:The boundary integral-Resonant Mode expansion method is used for the solution of the eigenvalue problem involved in the determination of the poles and the residues of the Y-parameters of arbitrarily shaped E-plane waveguide junctions. Using this method, the frequency response and its sensitivity to deformations of the boundary can be calculated much faster than by other more conventional methods for arbitrary shapes. Therefore, the described algorithm is eligible for setting up very efficient CAD tools to produce optimized designs of complex E-plane components in reasonable times. Some examples demonstrate the efficiency of the method in the Modeling of components of practical interest.

Wideband Modeling of arbitrarily shaped H-plane waveguide components by the "boundary integral-Resonant Mode expansion method"
IEEE Transactions on Microwave Theory and Techniques, 1996Co-Authors: G. Conciauro, P. Arcioni, M. Bressan, L. PerregriniAbstract:The paper describes a very fast and flexible algorithm for the wideband Modeling of arbitrarily shaped H-plane waveguide components. The algorithm is based on the evaluation of the poles and the residues of the Y-parameters by the "boundary integral-Resonant Mode expansion method." It also permits the fast evaluation of the effect of a deformation on the frequency response, a feature very useful either for optimization or for setting the mechanical tolerances. Some examples demonstrate the efficiency, flexibility, and reliability of the method. They show that the frequency response of complicated structures, such as multicavity filters, can be calculated in times of the order of one minute (or less) on ordinary workstations.

Modeling of losses in substrate integrated waveguide by Boundary Integral-Resonant Mode Expansion method
2008 IEEE MTT-S International Microwave Symposium Digest, 2008Co-Authors: Maurizio Bozzi, Luca Perregrini, Ke WuAbstract:This paper presents an efficient technique for the evaluation of different types of losses in substrate integrated waveguide (SIW). This technique is based on the Boundary Integral-Resonant Mode Expansion (BI-RME) method in conjunction with a perturbation approach. This method also permits to derive automatically multimodal and parametric equivalent circuit Models of SIW discontinuities, which can be adopted for an efficient design of complex SIW circuits. Moreover, a comparison of losses in different types of planar interconnects (SIW, microstrip, coplanar waveguide) is presented.

Modeling of Conductor, Dielectric, and Radiation Losses in Substrate Integrated Waveguide by the Boundary Integral-Resonant Mode Expansion Method
IEEE Transactions on Microwave Theory and Techniques, 2008Co-Authors: Maurizio Bozzi, Luca Perregrini, Ke WuAbstract:This paper presents the Modeling of lossy substrate integrated waveguide interconnects and components by using the boundary integral-Resonant Mode expansion method. The extension of the numerical technique to account for conductor, dielectric and radiation losses is discussed. Moreover, a systematic investigation of the different contributions of loss and their dependence on some geometrical parameters is performed in the case of interconnects and components, aiming at minimizing the losses. The physical explanation of the different effects is also provided. Finally, the validity of the equivalent waveguide concept is extended to the case of lossy interconnects and components.

A Wideband CP Crossed Slot Antenna Using 1- $\lambda $ Resonant Mode With Single Feeding
IEEE Transactions on Antennas and Propagation, 2017Co-Authors: C. F. Zhou, S. W. CheungAbstract:This communication proposes to use the 1-λ Resonant Mode of slot radiator with single feeding for bandwidth enhancement. The impedance of a simple slot radiator is studied using computer simulation. Since operating the slot radiator in the 1-λ Resonant Mode requires a longer slot length, a large square slot is used at both ends of the slot to reduce the required slot length. The results of the study are subsequently used to design a wideband circularly polarized (CP) crossed slot antenna (CSA) with single feeding. The CSA consists of two slot radiators having the same length and placed in a crossed shape, i.e., orthogonal positions. A single microstrip line with a via at the end is used to feed the CSA. By loading reactive elements with appropriate values on each slot near to the feed line, the two slots generate two linearly polarized electric fields with 90°-phase difference for CP operation. The CSA is studied and designed using simulation and measurement. Measured results show that the CSA has a wide impedance bandwidth of 1.52-3.44 GHz (1.92 GHz, 77.4%) and axial-ratio bandwidth of 1.73-3.01 GHz (1.28 GHz, 54%), much wider than the previous directional and bidirectional CSAs using single feeding.
