摘要
A tunable notch filter, comprises a transmission line coupled to an antenna; a plurality of ring resonators inductively coupled to the transmission line, wherein each ring resonator of the plurality of ring resonators is grounded and comprises a variable microelectromechanical systems (MEMS) capacitor; wherein a set of variable MEMS capacitors of the plurality of variable MEMS capacitors are independently tunable to vary a notch location and a notch width of the tunable notch filter; and wherein a set of ring resonators of the plurality of ring resonators further comprises an attenuator configured to reduce power reflected from the antenna.
