“…In previous researches, the radiating patch antenna was designed with rectangular, triangular, and circular shapes with step-shaped etching on the ground plane to enhance the bandwidth. The rectangular shape is a proper shape for the UWB antenna for a single port [13]. The proposed structure of a single antenna was designed on a print circuit board (PCB) with FR4.…”

This paper proposes a four-port rectangular monopole antenna for ultra-wideband multipleinput multiple-output (UWB-MIMO) applications. The proposed antenna was designed by using step etching on the ground plane and arrow-shaped slot etching on a radiating patch to enhance bandwidth and improve performances. The homogeneous elements and angular variation techniques were applied to reduce mutual coupling between multiple antenna elements. The structural simulation technique used Computer Simulation Technology (CST) program to analyze the antenna characteristics such as reflection coefficient, group delay, mutual coupling, envelope correlation coefficient, and radiation patterns. The measured results were found to cover a frequency range of 3.1-10.6 GHz for UWB communications. The envelope correlation coefficient for the MIMO system was obtained under 0.001 which is less than the specific parameters of UWB-MIMO antennas. The radiation pattern was bidirectional. Also, the efficiency of the four-port antenna was more than 85.70%.
