摘要: A planar filter for performing signal filtering at radio frequencies is provided. The can include asymmetrical resonators, wherein each resonator about a longitudinal center axis through the resonator. In addition, resonators be grouped in coupled pairs such that pair are between paired resonators. coupling structure provided includes both distributed and tapped to Further, bandstop device filter.
