Abstract
The research article outlines the evolution of a quad-element Luna-shaped UWB MIMO with enhanced isolation and gain using novel decoupling networks. The described MIMO module is tailored on a FR4 substrate of area 45 × 45 mm2 (0.378 λ0 × 0.378 λ0), where λ0 is estimated at 2.52 GHz, and 7 mm (0.0588 λ0) element to element separation between the radiators. It has 4 Luna-shaped radiators. The results achieved are S11 ≤ − 10 dB over the band 2.52–11.10 GHz, S21 ≤ − 20.75 dB, and S31 ≤ − 20.10 dB. The peak gain is 6.6 dBi, maximum efficiency is 98%, ECC ≤ 0.15, TARC ≤ − 10 dB, DG ≤ 10, MEG ratio ≈ 1, and CCL < 0.3 bps/Hz. This MIMO module is simulated by ANSYS HFSS and also measured results are presented.
