This paper described the design, simulation and fabrication of the ultra wideband (UWB) antennas for straight and U shape using seventeen elements log-periodic (LP) technique. The antennas have been modeled using microstrip lines and S parameter data from individual single element. The data is extracted from the momentum simulation and combined with the microstrip transmission line. The properties of antennas such as bandwidth return loss and radiation pattern have been investigated and compared between simulation and measurements. A bandwidth for UWB antenna is achieved using seventeen element arrays. The cross-polar isolation of the UWB antenna is in the range 8 to 20 (IB for straight shape. The typical half power bandwidth (HPBW) of the UWB antenna is 40deg. Furthermore, the return loss of the antenna is above -10 dB from both simulation and measurement.
