DESIGN AND B.W. OPTIMIZATION OF UWB (ULTRA WIDEBAND) ANTENNA
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 6
Abstract
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 [3]. 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 energy into the electromagnetic energy in form of electromagnetic waves [1]. 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 the 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 ofelements 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 communication 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.
