The designs of six compact resonant elements for communication systems of moving objects in the centimeter range are considered. A study of design options for resonant elements using electrodynamics finite element method is carried out. The aim of the work is to study various design solutions of resonant elements for the purpose of a comparative analysis of main quality indicators (gain, bandwidth, standing wave ratio, side lobes level and dimensions). An algorithm to integrate modern computing tools for modeling patch antennas is proposed and tested. The correctness of the simulation results is confirmed by a comparative analysis of the experimental results with the data of computer calculations obtained using finite element method in X-band.
Key words: resonator, electrodynamic simulation, computer experiment, X-band, communication systems, algorithm, design options, HFSS, gain, bandwidth, standing wave ratio, side-lobe level
