Enhancement of performance in the disk-shaped dual band microstrip patch antenna for the advanced IoT based 5G applications

Abstract

In this paper, the authors have enhanced the performance in the various characteristics of disk-shaped microstrip patch antenna very much useful for the latest fifth-generation (5G) wireless communication and its advanced Internet of Things-based applications. The whole purpose of this research work is for designing and analyzing the disk-shaped dual-band patch microstrip antenna at the resonance frequency of 28.5 GHz useful for advanced IoT-based 5G applications. In this research work, authors have used Rogers RT/Duroid 5880 substrate material of dielectric constant ?r= 2.2, the dielectric loss tangent of 0.0011, and thickness of the substrate of 0.72 mm. After simulating the design, the authors have obtained a good return loss of -21.5 dB at 28.5 GHz and -11.20 dB at 38.2 GHz, good bandwidth of 1.93 GHz, voltage standing wave ratio (VSWR) in the range 1 ? VSWR ? 2, and high gain of 10 dBi.
