Abstract

This project presented an ultra-wideband (UWB) bandpass filter using parallel coupled microstrip line. The proposed design of filter will be simulated, fabricated, measured and analyzed for UWB system application. UWB provides high data rates, resulting low interference, low cost, resistance to jamming and high performance in multipath channel compare to narrowband system which have interference signal in radio system, low channel capacity and costly. The expected of filtering range is about 3.1 GHz to 10.6 GHz. This filter also will be expected to produce low insertion loss. A planar bandpass filter, based on microstrip structure can provide the advantage of easy design, lower fabrication cost and compact size and has been widely used. It will provide low insertion loss over the band as a conventional filter, to have good performance at low frequency end and outside the operating band to meet the Federal Communication Commission (FCC) limit. AWR 2006 will be used for simulation of the filter while the fabrication will be done on Flame Retardant 4 (FR-4) board.
