Design and Analysis of a Six-Element UWB-X Band MIMO Antenna for High-Speed IoT, Imaging, and Radar Applications.

This research article reports a six-element multiple-input-multiple-output (MIMO) antenna for high-speed IoT, imaging, and Radar applications. The single-element UWB-X band antenna is designed and fabricated with asymmetric feed to achieve wider impedance-matched bandwidth. The antenna geometry is placed in planar on the 12-side polygon. A novel decoupling structure is used along with the ground plane which provides better isolation between each antenna and the antenna occupies an area of 8086mm2. The proposed 6 × 6 MIMO antenna design achieves measured bandwidth of 2.72–14.0 GHz. Also, prototypes are fabricated and full-wave simulation with experiment has been performed where S-parameters (reflection and transmission coefficients), the maximum peak gain of 6.65dBi, radiation pattern (stable), and diversity performance including ECC < 0.045, DG > 9.990 dB, TARC < −40 dB and CCL < 0.30 b/s/Hz has been evaluated.
