It is a communication method that is used in wireless networking. UWB has low power consumption due to which it can achieve high bandwidth connections. It transmits data over short distances without using too much power. Ultra wideband (UWB) antenna for wireless personal area network applications. The proposed antenna covers the impedance bandwidth of 3.1 to 10.6 GHz frequency range in free space. The design parameters for achieving optimal performance are investigated. A tapered microstrip feeding is employed to enhance the antenna matching. The operation and the characteristics of the proposed antenna are also analyzed. Good agreement has been obtained between the simulation and experimental results. The simulated and measured radiation patterns have demonstrated that the antenna is nearly omni-directional over the entire band.
