Wave Iterative Method for Patch Antenna Analysis

Abstract

Wave Iterative Method (WIM) is a numerical modeling for electromagnetic field analysis of microwave circuits. Theories of transmission line, four terminal network and boundary condition are applied to developing WIM simulation that the physical electromagnetic wave is described to a mathematical model using GUI function of MATLAB. In applying, the microstrip patch antenna was analyzed and implemented. The research result shows that the WIM simulation can be used correctly to analyze the electric field, magnetic field theory and return lose of sample patch antenna. The comparison of the WIM calculation agrees well with the measurement and the classical simulation.

Design, Analysis, and Modeling Using WCIP Method of Novel Microstrip Patch Antenna for THz Applications

“…The relation between these waves is developed from the reflection coefficient, formulated in the modal domain, and the scattering coefficient, formulated in the spatial domain. At the beginning of the iterative process, only the incident waves emitted by the excitation source exist in the structure [30][31][32][33].…”

“…It represents the nature of the walls of the case and the dielectric of the different media of the structure. The iterative process is used to switch from one domain to the other using FMT, thus allowing considerable reduction of the computation time and subsequently the convergence of the method [29][30][31][32]. The use of FMT requires the description in pixels of the different regions of the discontinuity plane (Ω) such that the electromagnetic behavior of a single or multilayer structure will be summarized by writing the boundary and continuity conditions of the tangential fields on each pixel [29][30][31][32][33].…”

“…The interface in which the circuit is defined is divided into small subdomains, and the interface contains four subdomains (insulator, metal, graphene, and source). Using the boundary condition in each region [30,32], it is possible to determine the overall diffraction factor, which relates the incident and reflected waves in the spatial domain.…”
