DESIGN AND ANALYSIS OF A COMPACT UWB BAN DPASS FILTER

Abstract

Ultra-Wideband (UWB) radio is a revolutionary, low power, and rapidly evolving technology, which employs short pulses with ultralow power for communication and ranging. A UWB impulse radio system does have several advantages, such as high data rate, high precision ranging, fading robustness, and low cost transceiver implementation. UWB is very promising for low-cost sensor networks. UWB bandpass filters play an important role in getting a high-quality signal while rejecting spurious and neighbouring unwanted signals. in this dissertation report we present a novel compact ultra wideband (UWB) band pass filter (BPF) using defected microstrip structure (DMS). Two different approaches have been used to analyze the design: 1. Transmission line analysis, 2. parametric variation analysis. In transmission line analysis the equivalent transmission line model is extracted and the results of frequency response are compared with simulated results. To realize ultra wide band bandpass filter characteristic the filter is designed based on the simulations from CST V12. The results from the simulation and measurement for these proposed antenna are presented, compared, and used as part of the validation process UWB operation.
