Compact Dual-Mode Open Loop Microstrip Resonators and Filters [PDF]
IEEE Microwave and Wireless Components Letters, 2009 A novel compact microstrip dual-mode resonator and filter are proposed. The characteristics of the dual mode resonator are investigated. It is found that the filter response exhibits a desirable stopband response where the first spurious passband ...

Information filtering in resonant neurons
Journal of Computational Neuroscience, 2015Neuronal information transmission is frequency specific. In single cells, a band-pass like frequency preference can arise from the subthreshold dynamics of the membrane potential, shaped by properties of the cell's membrane and its ionic channels. In these cases, a cell is termed resonant and its membrane impedance spectrum exhibits a peak at non ...

Concentric distributed resonators and filters
2018 IEEE Radio and Wireless Symposium (RWS), 2018In this paper we present a concentric, multiple resonant elements realization of a distributed filter. The proposed filter has 3 poles and is designed to operate at a frequency of 1.8 GHz with an absolute bandwidth of 40 MHz, equivalent to 2.22 %. Each resonant chamber of the presented filter consists of 25 individual resonant elements arranged in an ...

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007
A novel surface acoustic wave filter on a leaky-wave substrate is studied. It features a hiccup-type resonance occurring around a distributed gap between two long interdigital transducers. Compared to a classical coupled resonator filter, it enables a relatively narrow passband (1% to 2% of center frequency) with low insertion loss, steep skirts, and ...

Combline Filters using Conical Resonators
33rd European Microwave Conference, 2003, 2003This paper describes a novel configuration for combline filters employing conical rods as central conductors in the resonators. With respect to resonators with uniform rods, this shape allows a reduction of the capacitive loading for a given length of the resonator; as a consequence, a larger gap at the rods end can be employed (it is particularly ...

Multiple resonance FTR filters for nonpolarizing bandpass filters
Applied Optics, 1984A design procedure is given for multiple resonance FTR filters which are required to be nonpolarizing for a specific wavelength and angle of incidence. The optimum thickness of the buffer layer is derived to make the phase velocities of TE and TM modes coincide in a twin-waveguide system.

Dielectric resonators and filters
IEEE Microwave Magazine, 2007High-performance DRs and filters are widely used in wireless and satellite communication systems due to their superior characteristics, such as high unloaded Q, excellent temperature stability, and smaller size compared to their air-filled counterpart.

Coupled Resonator Filters (CRF) are a new form of bulk acoustic wave device that involves the vertical stacking of resonators. In that regard, the CRF can be thought of as a variation on the better known Stacked Crystal Filter (SCF). This paper will review the SCF and expand on the basic concepts of the CRF.
