Abstract

Wireless communication technology extensively explores and optimizes key parameters within a Multiple Input Multiple Output (MIMO) antenna system, with a primary emphasis on achieving high isolation and low correlation. The focus is to enhance the gain and Envelope Correlation Coefficient (ECC) while prioritizing diversity and Voltage Standing Wave Ratio (VSWR) optimization for 2*1 patch antenna. Through systematic design, simulation, and practical implementation, significant signal strength and reliability improvements are targeted. The directional focus will be finely tuned to maximize performance by adding 1–5 unit cells of the inverted E-shaped (IES) structure to improve the isolation. This work aims to provide valuable insights for developing high-performance MIMO antennas, with applications across evolving wireless communication technologies, by improving the performance in terms of correlation and isolation. The Proposed MIMO antenna has a very low ECC value of 0.001, diversity of 9.99 dB, VSWR of 1.32, and gain of 0.23 at 5.8 GHZ.

期刊介绍： Analog Integrated Circuits and Signal Processing is an archival peer reviewed journal dedicated to the design and application of analog, radio frequency (RF), and mixed signal integrated circuits (ICs) as well as signal processing circuits and systems. It features both new research results and tutorial views and reflects the large volume of cutting-edge research activity in the worldwide field today. A partial list of topics includes analog and mixed signal interface circuits and systems; analog and RFIC design; data converters; active-RC, switched-capacitor, and continuous-time integrated filters; mixed analog/digital VLSI systems; wireless radio transceivers; clock and data recovery circuits; and high speed optoelectronic circuits and systems.
