This paper presents a transparent super-wideband (SWB) MIMO antenna based on a metal mesh structure. The metal patch and substrate of the antenna are hollowed out, resulting in a transparency of up to 77% and a radiation efficiency exceeding 82%. The bandwidth of this MIMO antenna ranges from 1.6 to 19.2 GHz, achieving a bandwidth ratio of 12: 1. An engineered parasitic decoupling structure ensures that the isolation between antenna elements is greater than 25 dB, and the envelope correlation coefficient (ECC), diversity gain (DG), channel capacity loss (CCL), and total active reflection coefficient (TARC) all reach good values.
