Ultra wideband (UWB) technology is an ideal candidate for a low power, low cost, high data rate, and short rang wireless communication system. According to the Federal Communication Commission (FCC), UWB signal is defined as a signal having fractional bandwidth greater than 20% of the center frequency . Antennas are an integral part of everyday lives and are used for a multitude of purposes. Antenna is one type of transducer that converts electrical ene rgy into the electromagnetic energy in form of electromagnetic waves . These Monopole antennas combine the signals from multiple antennas in a way that mitigates multipath fading and maximize the output signal to - noise ratio. It can suddenly increase th e performance of a communication system. In the past, most papers apply genetic algorithms for searching the minimum side lobe level of the antenna [3,8].In desired phase weights determined by the scan angle and array geometry, the amplitude weights ofelem ents are optimized by differential evolution algorithm to drive down the side - lobes. In this project, a Monopole ultra wideband elliptical antenna array at the transmitter to synthesize an array pattern for minimizing the BER performance in a UWB communic ation system and To design & B.W. optimizations of UWB antenna. The electromagnetic software MWS - CST(Computer simulation technology simulator) is employed to perform the antenna design and optimization process.
