Abstract:

Based on the theory of the DRA and antenna feed mode,the thesis analyzes the influence of two factors on the antenna performance including the height and radius of the cylindrical dielectric resonators.Ansoft HFSS is applied to establish this model and the simulated VSWR is offered as a result.The simulation results show that the antenna performance is the best when R_c is 2.9 mm and H_c is 4 mm,and that the optimized parameters of the cylindrical dielectric resonator improve the performance of the antenna.

Key words: cylindrical dielectric resonator;electromagnetic emulation;VSWR
