A compact monopole ultra wide band (UWB) antenna is analyzed and described with defect in ground plane. By introducing four arcs at the edges of square patch is achieved an UWB antenna ranging from 3.1 to 10 GHz. Arranging the antenna elements in close proximity of spatial diversity is introduced without establishing the strong mutual coupling. The measured IBW's (impedance bandwidth's) are 3.0 to 4.0 GHz (1000 MHz), 5.6 to 4.3 GHz (1300 MHz), and 9.5 to 8.4 GHz (1100 MHz) occupied the bandwidth from 2.0 to 10.0 GHz which covers Bluetooth, WLAN, and ultra wideband for VSWR ≤2. The average value of the gain in antenna is 5.04 dBi with a small variation of ±1.20 dBi for the whole entire IBW. This antenna shows better radiation patterns like an omnidirectional with a narrow compact size having an area of 2100 mm 2 (60 × 35 mm) and spacing between the two square patches is 0.05 λ 0 .
