In this paper a novel and compact ultra-wideband crossed monopole antenna with a defected ground structure which is feed by microstrip line is presented. The impedance bandwidth of a rectangular patch antenna is maintained over the entire ultra-wideband frequency range and the response is improved by introducing defections of suitable dimension in the ground plane. The crossed monopole shows the return loss of 10 dB over the entire ultra-wideband frequency range (3.1 – 10.6)GHz while maintaining a stable radiation pattern. The effects of the Defected Ground Structure on the performance of the antenna are investigated. The software used for antenna design and simulation is HFSS V17.2.
