Design and Optimization of a 4×4 Patch Antenna Subarray for 5G Applications

Abstract

Fifth-generation (5G) technology is a cell phone system that aims to make wireless networks much faster and more responsive. In fact, 5G makes it possible to significantly increase the amount of data transmitted by the wireless system, with increased bandwidth and advanced antenna technology. According to an expanded bandwidth spectrum and advanced antenna technology. This article presents the development and simulation of rectangular microstrip patch antennas for wireless transmission at a frequency of 3.5 GHz. We simulated two varieties of antennas utilizing Computer Simulation Technology (CST) software. The design approach commenced with the development of a singular element, and then evolved into 4 × 4 element arrays. Microstrip feedlines feed the proposed 4 × 4 element arrays antenna, facilitating directed radiation, beneficial for the base station to ensure excellent quality, high-capacity network connectivity. The finalized antenna had a significant gain of 10.7 dB at a frequency of 3.5 GHz. The accumulated antenna results confirm that the proposed patch antenna is suitable for massive MIMO use in 5G applications.
