- Abstract
- The proposed Multi-Input Multi-Output lens antenna (MIMO-LA), integrated with a dual circularly polarized meta-transmissive surface (DCP-MTS), enhances the realized gain and aperture efficiency by effectively addressing key MIMO performance metrics, including diversity gain (DG), envelope correlation coefficient (ECC), mean effective gain (MEG), and multiplexing efficiency (Mx. Eff.). By incorporating an extended transition and reflective wall along with DCP-MTS, the MIMO-LA achieves a realized gain of 13.58 dBi, a DG of 10 dB, an ECC of 0.01, a MEG of −3 dB, Mx. Eff. of −3.02 dB, while maintaining an aperture efficiency of 50.8 % at the operating frequency f0 = 7 GHz. These results validate the effectiveness of the proposed design for 6G industrial applications, particularly in terrestrial, airborne, and non-terrestrial communications networks.
