Tubular resonant filter and method of making a tubular resonant filter
A tubular resonant filter comprises a multilayer sheet in a rolled configuration comprising multiple turns about a longitudinal axis, where the multilayer sheet includes a strain-relieved layer, a patterned first conductive layer on the strain-relieved layer, an insulating layer on the patterned first conductive layer, and a patterned second conductive layer on the insulating layer and the patterned first conductive layer. The patterned first and second conductive layers and the insulating layer are interrelated to form a rolled-up inductor connected to a rolled-up capacitor on the strain-relieved layer.
