Ultra-wideband Antenna System Design for Future mmWave Applications

Year: 2025

Type: article

Abstract: An ultra-wideband planar four-element multiple-input multiple-output (MIMO) antenna array for millimeter wave (mmWave) 5G applications is presented in this article, characterized by a simple structure and diverse performance capabilities. The antenna system operates in the 20 GHz band (ranging from 42.3 to 63.3 GHz), with a high gain of 7.8 dB. The compact size of 25 × 25 mm makes it suitable for being integrated with various telecommunication devices used in a number of mmWave applications. The antenna's elements are placed orthogonally, achieving great isolation of over 24 dB. The performance of the proposed antenna was analyzed in terms of its s parameters, gain, efficiency, radiation patterns, and MIMO diversity characteristics, including the envelope correlation coefficient (ECC), diversity gain (DG), and mean effective gain (MEG).
