In this letter, a novel compact ultrawideband (UWB) bandpasss filter (BPF) using the proposed multiple-mode resonator (MMR) is presented. The MMR is composed of a conventional microstrip hairpin resonator of which the two arms are connected by a section of microstrip line and a short-circuited point located in the middle of the hairpin resonator. Its first three resonant modes call be utilized to construct the UWB hand. The tapped feeding structure has been used to realize desired tight couplings for designing the UWB BPF. The filter has been investigated numerically and experimentally. Both the simulated and measured results show that the filter has good performance, such as compact size, low-insertion loss, small group delay variation, and improved out-of-hand performances.
