Quad-Port Staircase U-Shaped Wideband MIMO Antenna for 5G New Radio Applications
By
Progress In Electromagnetics Research Letters, Vol. 125, 43-50, 2025
Abstract
This article introduces a quad-port Multiple Input Multiple Output (MIMO) staircase U-shaped wideband antenna for a 5G New Radio (NR) wireless. The miniaturization of the configuration is achieved with a staircase U-shaped radiating element, and an I-shaped stub etched with rectangular strips between radiating elements provides enhanced isolation. The measured bandwidth of 4.5 GHz is obtained with an isolation, radiation efficiency, and gain above 17 dB, 80%, and 6.5 dB respectively. Certain parameters, such as envelope correlation coefficient (ECC), diversity gain (DG), mean effective gain (MEG), channel capacity loss (CCL), and total active reflection coefficient (TARC), are also evaluated to ensure that the designed MIMO system adheres to its requirements. Hence, the suggested antenna suits the 5G New Radio applications.
