| Research Abstract |
Because of the important performance benefits associated with ultra-wideband UWB communication systems, UWB bandpass filters (BPFs) are on the cutting edge of UWB technologies and are of great interest to researchers and engineers in the areas of RF filters and systems. In this study, a novel synthesis technique is proposed for the design of UWB filters with fractional bandwidths (FBWs) over110%. Furthermore, several UWB filters with high-performance are designed and developed. (1) In terms of transmission line theory, design/characteristic equations are established after the derivation of the theoretical real filtering functions for high-order equi-ripple UWB filters. (2) A new class of UWB filters composed of parallel-coupled stepped-impedance resonators (SIRs) and short-/open- circuited stubs is proposed, hence, UWB filters satisfying FCC’s specifications are experimental realized.
