A compact concaved H-shaped patch antenna for dual-band applications with improved bandwidth and isolation characteristics is presented in this paper. The proposed antenna resonates at multiband of 3.2GHz and 4.9GHz frequencies for VSWR less than 1.32, with an impedance bandwidth of 70%. A 2x2 MIMO system is developed using the proposed antenna giving an excellent isolation of 48dB between the two antennas. The developed antenna system can be widely used for the 4G, WLAN and WiMAX applications. The proposed antenna is a good choice for Multiple Input and Multiple Output (MIMO) systems operating for several wideband applications.
