“…The basis of equivalent port representations is the creation of new sets of port voltages and currents which consist of linear combinations of the port voltages and currents of another port description. A generalized procedure to do this was presented in [1], together with a number of examples showing the implementation for classical circuit and antenna problems. Here, a brief mathematical overview is given, and the reader is referred to [1] for details.…”

“…Recently, the author developed a transformation technique which allows for the transformation of multiport S-parameters between different sets of excitations, using only one set of EM-analyses [1,2]. The technique works for coupled and uncoupled ports, and is very simple to implement.…”

This paper will show how the utilization of the Generalized Multi-Mode Scattering Parameter Transformation for multiport S-parameters can result in the reduction of the number of S-parameters needed to model a multiport network, and how correct choices can result in S-parameters which exhibit improved numerical behaviour in a given parameter space. An example of a two-port, six-line transmission line with the conductors spaced as pairs is used to show the difference between sets of common-differential mode excitations, and sets of singleended excitations will be shown.

“…As reported in [4], the multi-mode response of the quadmode antenna can be obtained from conventional Single-Ended (SE) radiated far-field pattern measurements where each SE far-field is measured by individually exciting each port with the remaining three ports terminated in a matched load. Figure 4 compares the multi-mode co-polar gain, transformed from SE far-field measurements, to the co-polar gain simulated in CST using the multi-mode port excitations illustrated in Figs.…”

This article applies the generalized multimode S-parameters to multiport antennas and radio frequency (RF) components for CAD applications. Consider the special case of impedance matching which could significantly simplify the multimode representation on port and remove the requirement on calculating port impedance. N single-ended ports of a network are regarded as one generalized multimode port, supporting N orthonormal modes represented by N orthonormal basis vectors, respectively. By doing this, in antenna and RF component designs, one can only focus on specific modes interested, while ignore others. A multiport network's characteristics could be represented and understood in a much simpler manner because fewer but more intuitive physical quantities are considered. Therefore, this can significantly simplify the analysis, design, and optimization of multiport networks. For better illustration, several examples, including branch-line coupler, mixed-mode case, sequential rotation feeding antenna, and monopulse feed are analyzed and designed. Complicated analyses in network design using the single-ended S-parameters, including matching, amplitude and phase unbalance, could be converted into much simpler ones from the generalized multimode perspective.
