Abstract :
In this paper, a Multi-Input Multi-Output (MIMO) antenna is proposed. The isolation characteristic of proposed MIMO antenna between two radiating elements is improved by using a Split Ring Resonator (SRR) array structure. The fabricated antenna satisfied the 10 dB return loss requirement and the isolation between the two radiating elements was higher than 15 dB in the Mobile-WiMAX frequency band. The measured peak gains of the two elements were 2.3 dBi and 2.4 dBi.
