1. A serpentine resonant transmission line formed on or in a substrate, comprising:

  • an electrically conducting path folded to induce electromagnetic coupling between adjacent conducting line segments that form;

    capacitive loads along coupled conducting line segments in which the instantaneous currents within a portion of the coupled conducting line segment is oriented anti-parallel to the instantaneous current vectors within an adjacent conducting line segment, and,inductive loads along other coupled conducting line segments in which the instantaneous currents within a portion of the coupled conducting line segment is oriented in parallel to the instantaneous current vectors within an adjacent conducting line segment;

    and, ceramic dielectric material inserted between the coupled line segments to control reactive loading along the serpentine transmission line structure,wherein the capacitive and inductive reactive loads distributed along the folded conducting paths are used to tune the resonant frequency or frequencies of the serpentine resonant transmission line.
