A compact broadband antenna array with two identical antenna elements is proposed to realize high isolation that is realized via integrating a new wheel-like meta-material structure into the closely set antenna elements. The wheel-like meta-material decoupling structure is settled between the two antenna elements to reduce the coupling from the nearby antenna element. The proposed antenna array is designed, optimized, fabricated and measured in a chamber. The achieved results verify that the developed antenna is able to provide a wide bandwidth ranging from 8 GHz to 12 GHz. Using the developed wheel-like meta-material decoupling structure, not only the designed antenna array maintains performance of MIMO array, but also the coupling is reduced to be less than -20 dB within the X-band. Therefore, the proposed antenna array is a suitable candidate for X-band MIMO radar system applications to get a high isolation between the elements.
