Abstract
An inductive-capacitive filter includes a first insulating-conductive strip wound around a winding axis, where the first insulating-conductive strip includes a first conductive strip joined with a first insulating strip. An inductive-capacitive filter assembly includes a first and a second insulating-conductive strip concentrically wound around a winding axis, the first insulating-conductive strip including a first conductive strip joined with a first insulating strip, and the second insulating-conductive strip including a second conductive strip joined with a second insulating strip.

A method of forming an inductance-capacitance filter comprising:
- winding multiple turns of a first insulating-conductive strip and a second insulating-conductive strip, the first insulating-conductive strip having a first insulating strip joined with a first conductive strip and the second insulating-conductive strip having a second conductive strip and a second insulating strip, the winding of the first and second insulating-conductive strips being about a common winding axis;
- forming a first capacitance from capacitance between the multiple turns of the first insulating-conductive strip;
- forming a first inductance-capacitance resonant circuit comprising resistance of the first conductive strip, inductance of the first conductive strip, and the first capacitance;
- and
- coupling a first end of the first conductive strip to an input of the inductance-capacitance filter and a second end of the first conductive strip to an output of the inductance-capacitance filter.
A method of forming an inductance-capacitance filter comprising:
- layering together a first insulating-conductive strip and a second insulating-conductive strip, the first insulating-conductive strip having a first insulating strip joined with a first conductive strip and the second insulating-conductive strip having a second insulating strip joined with a second conductive strip, the first and second conductive strips separated from each other by at least one of the first and second insulating strips;
- winding multiple turns of the layered insulating-conductive strips;
- forming a first capacitance from capacitance between the multiple turns of the first and second conductive strips;
- forming an inductance-capacitance resonant circuit comprising inductance of the conductive strips, and the first capacitance;
- and
- coupling a first end of the first conductive strip to an input of the inductance-capacitance filter and a second end of the first conductive strip to a first output of the inductance-capacitance filter.
