A 2´1 (two-element) multiple-input multiple-output (MIMO) patch antenna system is designed and fabricated for (2.43 – 2.57) GHz LTE band 7 operation. It uses comple-mentary split -ring resonator (CSRR) loading on its ground plane for antenna miniaturization. This reduces the single-element antenna size by 76%. The total board size of the proposed MIMO antenna system, including the GND plane is 50´50´0.8mm3, while the single-patch antenna element has a size of 18.5 ´16mm2. The antenna is fabricated and tested. Measured results are in good agreement with simulations. A minimum measured isolation of 10 dB is obtained given the close interelement spacing of 0.17λ
