Ultra Wideband (UWB) communication system is used for large bandwidth, low power, signal transmission and reception over a short distance.  In an UWB system, digital signals are transmitted in air by using extremely narrow radio frequency pulses. In order to transmit and receive UWB signals in air an ultra wideband antenna is needed. An Ultra Wideband (UWB) antenna operates over the UWB band, which ranges from 3.1 to 10.6 GHz. In this project several versions of a printed wideband monopole antenna have been designed.

Advanced Design SystemŽ (ADS) tools were used to optimize the coplanar waveguide of the UWB antenna.  In order to optimize the antenna, the radiating part and coplanar waveguide ground plane will be cut at angles of 0, 30, 45, 60, and 75 degrees.  All designs will be fabricated and tested.  The design with the best test results will be considered the optimal design.
