Optimization of RF and Antenna Systems for Reliable High-Frequency Communication in 5G and IoT Networks

Abstract

The blistering development of 5G and Internet of Things (IoT) technologies has enhanced the necessity of the high-frequency communication systems that are reliable to a great extent. But, functioning on the high-frequencies brings about serious concerns, such as the harsh propagation loss, signal attenuation, interference, and inefficiency of hardware, that deteriorate the overall system performance. This article introduces a system of combined optimization of RF front-end systems and antennas in order to improve the reliability of communications in the 5G and IoT network. The combined optimization of critical RF parameters (gain, noise figure, and power efficiency), as well as the antenna behaviour (return loss, or S11) or bandwidth, and radiation efficiency are all optimised by the proposed way. An optimization strategy based on a parameter is used our system level performance has been enhanced by optimising the structure of RF products and antenna size by various methods in an iterative manner. The co-optimization strategy that is proposed creates an effective impedance matching, minimised signal distortion, and maximised power usage. The results of simulations have shown that the optimised system attains better gain, much lower return loss, and increased energy efficiency than normal approaches of independent design. In addition, the model proposed improves the reliability of communication in different channel conditions. These findings affirm that the unified optimization of RF and antenna sub systems offers a scalable, energy-saving, and high-performance next-generation communication systems of 5G and IoT.
