This work proposes the dielectric resonator antenna consisting of four identical adjacent rectangular, excited by an aperture coupling, taking advantage of the properties of the dielectric materials of two composite materials samples based on a mixture of epoxy resin (RE) and barium titanate (BaTiO3), which we experimentally obtained through the use of the time domain spectroscopy (TDS) measurement method. The geometric parameters are selected in order to achieve the optimum antenna performance. The proposed dielectric resonator antenna gives three frequency bands. The lower band covers a range of frequencies from 4.82 to 6.11 GHz, the middle frequency band covers from 8.61 to 10.70 GHz and the upper band covers a range of frequencies from 13.54 to 14.19 GHz, with a peak gain of 6.8 dB.

摘要

This work proposes the dielectric resonator antenna consisting of four identical adjacent rectangular, excited by an aperture coupling, taking advantage of the properties of the dielectric materials of two composite materials samples based on a mixture of epoxy resin (RE) and barium titanate (BaTiO3), which we experimentally obtained through the use of the time domain spectroscopy (TDS) measurement method. The geometric parameters are selected in order to achieve the optimum antenna performance. The proposed dielectric resonator antenna gives three frequency bands. The lower band covers a range of frequencies from 4.82 to 6.11 GHz, the middle frequency band covers from 8.61 to 10.70 GHz and the upper band covers a range of frequencies from 13.54 to 14.19 GHz, with a peak gain of 6.8 dB. Ansys HFSS, software was used for antenna design and simulation.
