    DESIGN OF A DUAL BAND COMPACT MIMO ANTENNA FOR S AND D BAND APPLICATIONS
    Shiddanagouda F B*, P V Hunagund, Vani R M

    The proposed MIMO (multiple input multiple output) antenna consist of compact four channel MIMO microstrip antennas whose incremental distance of 0.5λ was kept between adjacent patch elements, the four antenna elements were placed orthogonally from each other. The proposed MIMO antenna was operating at 2.6 GHz and 5.1 GHz with -15.2 dB and -20.1 dB isolations respectively for S and C radio band applications. The introduction of complimentary octagon split ring slot defected ground structure (COSRSDGS) integrated with MIMO antenna leads to limits the surface wave between them and reduction of mutual coupling by -25 dB and -20 dB with respect to resonating frequencies 2.6 GHz and 5.1 GHz respectively. The system can cover a 75.2 MHz and 290 MHz operating bandwidth with total size of 40 x 40 x 1.6 mm3. The simulated and measurement results such as return loss, impedance bandwidth, VSWR (Voltage Standing Wave Ratio), gain, mutual coupling coefficients and radiation pattern, envelope correlation coefficient (ECC), diversity gain were identified as having good performance of the MIMO antenna.
