The ACS-fed MIMO antenna is designed using two triple band antenna elements, operating at 4.6 GHz, 4.9 GHz and 5.4 GHz with good matching (reflection coefficient is less than-20 dB). By using mushroom like electromagnetic bandgap structure, further mutual coupling isolation (better than 30 dB) is achieved. The overall MIMO antenna size is compact (46.5 � 26 mm 2 ). The MIMO antenna has less than 0.02 envelope correlation coefficient (ECC) and maximum than 9.98 dB diversity gain. The results are simulated using full wave simulations. � 2018 IEEE.EnglishOctober University for Modern Sciences and Artsجامعة أكتوبر للعلوم الحديثة والآدابUniversity of Modern Sciences and ArtsMSA UniversityAntenna feedersMetamaterial antennasMetamaterialsMIMO systemsWaveform analysisAsymmetric coplanar stripComposite right/left handed (CRLH)Electromagnetic bandgap structuresEnvelope correlation coefficientFull-wave simulationsMulti-band operationsMultiple input multiple output antennasTriple band antennasMicrowave antennasConference Paperhttps://doi.org/10.1109/MetaMaterials.2018.8534131PubMed ID :
