Novel dual element antenna arrays suitable for small devices of MIMO applications have been designed and fabricated. The antenna elements have semi-printed structure, are fractaly shaped and operate in ISM(2.4GHz -2.489GHz) band as well as between 5GHz and 6GHz. Although the size of the designed antenna prototypes are small and the elements are positioned too close to each other, correlation coefficients lower than 0.1 and satisfactory levels of Mean Effective Gain have been obtained.
