In this paper, the authors present the design of a 2.77GHz MIMO antenna with two rectangular patches loaded by two Split Ring Resonator (SRR) as the antenna elements. Each antenna element has area of 56x25mm2. A compact and low correlation coefficient antenna system covering bandwidth 178MHz for wireless communication standards is proposed. First, a linearly polarized rectangular patch antenna is discussed. In order to increases the circular polarization; the patch structure is further modified into split ring structure. An array of such split ring is then constructed to increases the directivity, axial ratio, gain and efficiency.
