A four-element UWB MIMO antenna using SRRs for application in satellite communications

This paper proposes a method for designing new <em>ultra wide band</em> (UWB) multiple-input multiple-output (MIMO) antenna with two and four elements. First we presented an ultra-wide band studied these performances. Then, the application of metamaterials to design MIMO antennas miniaturization performance antennas, in order guarantee proper functioning system much reduced separation distance between radiating elements (λ/12), where coupling can be very weak. The circular double ring SRRs materials on front plan has contributed increasing is terms S-Parameters, efficiency, diversity gain (DG), radiation properties envelop correlation coefficient (ECC). It offers advantages such as reduction weight congestion that beneficial their integration into satellite communications systems.
