Abstract: This paper deals with the effects of the pattern caused by the antenna dome construction. The geometrical optical method and radial track are used in the analysis. The patterns with the loaded dome and unloaded dome on the antenna surface are given. The simulation is made by computer. The simulation results show that this method is effective for the analysis of the antenna parameters in many types of dome and for the evaluation of antenna parameters.

Key words: antenna dome, pattern analysis, computer simulation
