A miniaturized silicon-based ground ring guarded patch resonator and filter
A new miniaturized ground ring guided microstrip patch filter developed on the silicon wafer using micromachined technology is reported. The ground shunt can be used to lower the operating frequency up to one-third as ...
A compact size coupling controllable filter with separate electric and magnetic coupling paths
This paper presents the characteristics of a miniaturized microstrip filter, which has two separate coupling paths: electric coupling path and magnetic coupling path between two resonators. Either magnetic coupling or ...
An ultra-compact hairpin band pass filter with additional zero points
A novel quasi-hairpin filter is presented in this letter. The generation of zero points is investigated. Second-order and fourth-order filters, based on separate coupling paths, have been implemented. The filters show ...
An ultra-compact planar bandpass filter with open-ground spiral for wireless application
A common via filter is investigated and designed by using a proposed scalable lumped circuit model. The model-based result of the filter agrees well with that of the measurement. An ultra-compact open-ground spiral filter ...
A compact coupling controllable elliptical filter based on multilayer LTCC
This paper presents a compact elliptical filter based on modified λ/4 resonators with separated electric and magnetic coupling paths. For the proposed second-order filters, transmission zero points are generated at either ...
Design of quarter-wavelength resonator filters with coupling controllable paths
This paper presents compact quarter-wavelength resonator filters to have multiple transmission zeros points (ZPs) with controllable electric and magnetic coupling paths. For two coupled resonators, the relative strength ...
