AN INVESTIGATION AND IMPLEMENTATION OF WIDEBAND DIELECTRIC RESONATOR ANTENNA FOR 5G WIRELESS COMMUNICATIONS

Abstract

The comprehensive deployments of 5G networks are at a fast pace and are predictable to deliver extraordinary data rate, little latency rate, effective Electro Magnetic spectrum exploitation compared to 4G. To increase network capacity, the 5G NR air interface allows a diverse spectrum in the sub-6 GHz frequency bands. The Proposal includes current technologies on Fifth Generation multiband square dielectric resonator antenna for the future wireless communication system. A diverse Dielectric Resonator Antenna (DRA) is accessible on behalf of wide-ranging band applications; wideband DRA design improves three aspects: a compact T-shaped rectangular dielectric resonator, a correct angle between directions within small areas for reversed trapezoid micro strip as a feed mechanism, and an RT Duroid 5880 substrate as a base. Furthermore, a conventional square DRA of the same frequency for the determination of comparison is designed. The projected dielectric antenna resonating from 3 to 5.7 GHz with 2.78 GHz of extensive impedance bandwidth in which it covers the targeted 5G bands up to sub-6 GHz, having a good return loss below -10 dB. Additionally, the suggested DRA has an extreme radiation efficiency of 98.3%>97.7% complete radiation efficiency and maximum gain is 5.93 dBi. Alternatively, the proposed DRA will resonate at 3.8 GHz with 302 MHz of restrained impedance bandwidth, having reasonable return loss. The proposed antennas are simulated using the 3D EM simulation tool of CST Microwave studio. Together they suggested antennas consume a closely omnidirectional radiation pattern at resonance frequencies, through VSWR<2. Relative study of the double suggested antennas regarding return loss, impedance bandwidth, VSWR, radiation pattern, and gain obviously. It illustrates the performance of T-shaped DRA over rectangular DRA at 5G is a good agreement.
