摘要：
—The present work describes a new wideband circularly polarized MIMO rectangular antenna in cube form for X-band application (8 to 11.8 GHz). The proposed antenna structure shows pattern diversity in whole 360◦ angle with polarization diversity. The isolation between the antennas is more than −14.5 dB. The impedance matching bandwidth (IMBW) is 3.8 GHz, and 3 dB axial ratio bandwidth is 2.91 GHz. The envelope correlation coefficient is less than 0.035, and its diversity gain is 10 dB. A copper metallic cylinder is placed inside the cube antenna to reduce the mutual coupling between the antennas. © 2020, Electromagnetics Academy. All rights reserved.
