Optimum Rectangular Dielectric Resonator Antenna for Sub-6GHz in Rapid 5G Communication Networks

The design and analysis of an RDRA(rectangular dielectric resonating antenna is reported in this study. This resonance is attained with a significant S11 value of -26 dB. The bandwidth of the antenna is 5.5 to 6.5 GHz. In addition to the antenna’s gain, bandwidth, and reflection coefficient, performance metrics like VSWR, impedance, and directivity are also examined. Taking into consideration of all the performance metrics, the suggested antenna is appropriate for nowadays developed Sub-6GHz 5G communication. The results of this study have significant implications for the deployment of high-gain compact patch antennas for sub-6 GHz and sub-7 GHz 5G wireless communications and demonstrate the potential of the proposed design to enhance the efficiency in these radio frequency. This study presents a dielectric resonator antenna (RDRA) with a rectangular form. Excellency of this work is the simultaneous employment of MATLAB and HFSS software for researchers of antenna community. The design equations are executed in HFSS and found the best suitable dimensions of the RDRA. Considering these dimensions the RDRA is designed and the simulation results with high radiation efficiency are obtained in HFSS. The RDRA is designed with dielectric resonating material Rogers RO3210 ( ϵ r = 9.8) and traditional FR4 substrate. The RDRA operates in sub-6 GHz range resonating at frequency 6.1 GHz.
