  • Filtering device and filtering assembly having an electrically conducting strip structure
    Patent number: 10476121
    Abstract: A filter device includes a transmission line formed by an electrically conducting strip printed on a surface of an electrically insulating substrate, the conducting strip having two ends respectively forming the two sole input and output connection ports of the filter device, and a plurality of resonators, each resonator including an electrically conducting strip printed on the surface of the substrate. The conducting strip of each resonator has a first end coupled to the transmission line and at least one second end that is free or connected to a ground so as to create an effective fundamental resonant wavelength specific to each resonator. For each pair of neighboring resonators of the plurality of resonators, the distance between the first ends of the two neighboring resonators is less than one tenth of the smallest effective fundamental resonant wavelength of the plurality of resonators.
