• Compact UWB Bandpass Filter Using Stub-Loaded Multiple-Mode Resonator (2007, background): “In our initial works [9], [10], open-ended stubs are introduced at the center of a stepped-impedance resonator to allocate the first two resonant modes more closely with each”
• Compact Ultra-Wideband Bandpass Filters Using Composite Microstrip–Coplanar-Waveguide Structure (2006, background): “These UWB filters have sharp rejection, but their spurious response would degrade the out-of-band response and an increase in number of sections may lead to large insertion loss, as well as poor group delay.”
• Short-circuited CPW multiple-mode resonator for ultra-wideband (UWB) bandpass filter (2006, background): “Its basic idea was originated in [10] to achieve a broad fractional passband of 60%–80% in terms of the first two resonant”
• An optimum ultra‐wideband microstrip filter (2005, methodology): “Alternatively, an aperture-compensation technique was proposed for the effective enhancement of coupling strength in parallel-coupled microstrip line and a filter of this type exhibited FBW of 70% [3].”
• A Microstrip Ultra-Wideband Bandpass Filter With Cascaded Broadband Bandpass and Bandstop Filters (2007, methodology): “In addition to parallel-coupled lines and stepped-impedance resonators, the ground-plane aperture is employed to improve the coupling coefficient [2], while the capacitive loading is used to enhance the rejection in the higher stopband [3].”
• Ultra-wideband bandpass filter with hybrid microstrip/CPW structure (2005, unknown): “The basic principle of this UWB filter originated in [8] and [9] to explore compact and broadband BPFs with the bandwidth of 60% 80%.”
• Ultra-wideband (UWB) bandpass filters using multiple-mode resonator (2005, methodology): “poles are contributed by the two quarter-wavelength coupled line sections with enhanced coupling degree [9]–[11].”
• Broadband quasi-Chebyshev bandpass filters with multimode stepped-impedance resonators (SIRs) (2006, methodology): “There have been many good BPF examples designed with a single triple-mode SIR in [8]–[10], and they will be not repeated here.”
• A Novel Band-Reject Frequency Selective Surface With Pseudo-Elliptic Response (2010, background): “Each resonator contributes to one reflection zero at a frequency where its electrical length becomes equal to [ 15 ], [16].”
