Modeling non-conventional monopoles in COMSOL Multiphysics
Zmeškal, Vladimír ; Olivová, Jana (referee) ; Raida, Zbyněk (advisor)
The project deals with the computer simulation of non-conventional monopoles in the program COMSOL Multiphysics. First, the methodology for using COMSOL Multiphysics is described. Second, we concentrate on the design and modeling of three types of non-conventional monopoles: the conical one, the capacitively loaded one, and the drop-shaped one. For each monopole, directivity patterns are displayed. The influence of the variation of antenna dimensions to its parameters is discussed. Monopoles are mutually compared. Finally, models of monopoles are completed by global optimizations techniques: genetic algorithms and particle swarm optimization. That way, a design tool is developed in MATLAB.
