In this paper, a compact microstrip patch antenna working on the Ultra Wideband (UWB) has been designed. The antenna was designed using a defected ground structure. The S parameter results show that for this antenna, S11 < −10 dB for the UWB range (3.1–10.6 GHz). Further, this single antenna was used to design a MIMO antenna with two antennas where both the antennas were placed orthogonal to each other. This two antenna system was further analyzed that showed that both the antennas were working independently of each other in the UWB range and also the mutual coupling between the two antennas is also very less. The antennas showed minimum attenuation at a frequency of about 9.4 GHz that can be used for RADAR applications. The antennas were simulated on CST Microwave Studio and the simulation results were further analyzed.
