Abstract (en)

The invention discloses a method to manufacture a high frequency electrical resonator for the ignition system of an internal combustion engine, the method comprising the steps of: providing a coil (50) and a tubular electrically conductive shield (30), manufacturing a tubular encapsulation pre-form (40) having outer and inner dimensions such that the coil (50) freely enters the pre-form (40) which can itself fit inside the shield (30), inserting the pre-form (40) inside the shield (30), placing the coil (50) inside the pre-form (40) and, filling the gap between the coil (50) and the pre-form (40) with a dielectric fluid (60) having a viscosity enabling to entirely fill the gap.
