Abstract: In this paper, a tunable dual-band bandpass-to-bandstop filter and its analysis are proposed. The bandpass-to-bandstop transformation could be obtained by changing the state of the p-i-n diode. Using two sets of half-wavelength resonators loaded with… read more here.

DOI: 10.1109/lmwc.2018.2874129
Abstract: Coplanar stripline (CPS) bandpass and bandstop filters may be built using spurline stub resonators. Previous papers have demonstrated these filters, but they had a parasitic resonance that may limit spurline resonators from being used in… read more here.

DOI: 10.1109/tap.2019.2891451
Abstract: A design of the double-element E-plane quasi-Yagi–Uda antenna is proposed offering two different radiation patterns and reconfigurable bandpass-to-bandstop frequency-tunable responses. The double-element antenna covers a wide frequency range that is exploited for the realization of… read more here.

DOI: 10.1109/tcsii.2022.3202635
Abstract: This brief is to present a resonator reuse approach in implementing a high-attenuation notch next to a passband. Each resonator is utilized twice in producing bandpass and bandstop responses at the same time, which leads… read more here.
