Design and Comparative Analysis of Various Antenna Array Structures for 5G Applications

The emergence of the 5G technology has ushered in a system that offers data rates, low latency, and improved wireless communication. This project focuses on investigating array structure configurations specifically designed for antennas with a primary emphasis on their applications in the realm of 5G. The study involves the design of multiple MIMO antennas to determine the most suitable array structure. These MIMO antennas are designed to operate within a Frequency for 5 G Applications with sub-band 6 GHz and 5 G Frequency range spanning from 3.5 GHz to 6 GHz. Additionally, the performance of array configurations is meticulously compared, taking into account factors such as directivity, gain, VSWR (Voltage Standing Wave Ratio), and polarization ratio. A Chair-Plane antenna is designed. At the top substrate, a chair-shaped patch with etched out. At the bottom of the antenna, a rectangular shape is placed. An array of microstrip feed lines feeds the antenna. FR4, identified by a dielectric continuous ($\varepsilon$ r) of 4.4 as well as a loss tangent $(\tan \delta)$ of 0.02 is the structure that is made use of. The measurements of the antenna are $50 \times 39 \times 1.6 \mathrm{~mm}$ in overall. Simulated values of return loss at resonating frequencies are 3.5 GHz, and 5 GHz are observed at -23.59, and -20.91dB respectively. The Chair-plane antenna exhibits 5.01 dB gain and 5.38 dB directivity and a VSWR value of 1.15 and 1.19GHz is obtained. This Chair-Plane antenna is resonant at the C band. Thus, utilizing this suggested antenna it can be made use of for real-time 5 G applications that utilize C band as a reverberating regularity.
