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 \(\varepsilon_{r} = 2.2\), 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 \(1 \le {\text{VSWR}} \le 2\), and high gain of 10 dBi. |
